Influence of Occupant Behavior for Building Energy Conservation: A Systematic Review Study of Diverse Modeling and Simulation Approach
Publisher: MDPI AG
Date: 26-01-2021
DOI: 10.3390/BUILDINGS11020041
Abstract: Energy consumption in buildings depends on several physical factors, including its physical characteristics, various building services systems/appliances used, and the outdoor environment. However, the occupants’ behavior that determines and regulates the building energy conservation also plays a critical role in the buildings’ energy performance. Compared to physical factors, there are relatively fewer studies on occupants’ behavior. This paper reports a systematic review analysis on occupant behavior and different modeling approaches using the Scopus and Science Direct databases. The comprehensive review study focuses on the current understanding of occupant behavior, existing behavior modeling approaches and their limitations, and key influential parameters on building energy conservation. Finally, the study identifies six significant research gaps for future development: occupant-centered space layout deployment occupant behavior must be understood in the context of developing or low-income economies there are higher numbers of quantitative occupant behavior studies than qualitative the extensive use of survey or secondary data and the lack of real data used in model validation behavior studies are required for erse categories building building information modeling (BIM) integration with existing occupant behavior modeling/simulation. These checklists of the gaps are beneficial for researchers to accomplish the future research in the built environment.

Multifold Nanostructuring and Atomic‐Scale Modulation of Cobalt Phosphide to Significantly Boost Hydrogen Production
Publisher: Wiley
Date: 06-09-2018
Abstract: Water electrolysis is regarded as a green and highly efficient approach to producing high-purity hydrogen, but commercialization of this technology still requires the development of high-performance and affordable electrocatalysts for the hydrogen evolution reaction (HER). Currently, because of its excellent electrical conductivity and good corrosion resistance in acidic media, cobalt phosphide (CoP) has become a representative non-noble-metal HER catalyst despite its inadequate catalytic activity. Herein, a strategy of multiple catalyst-structure engineering, which simultaneously includes doping, nanostructuring, and in situ nanocarbon coating, was employed to significantly improve the HER performance of CoP. CoP with optimized ruthenium doping and covered by ultrathin graphitic carbon shells shows remarkably high HER catalytic behaviour with a low overpotential of only 73 mV at a current density of 10 mA cm

Bridging the Charge Accumulation and High Reaction Order for High‐Rate Oxygen Evolution and Long Stable Zn‐Air Batteries
Publisher: Wiley
Date: 11-03-2022
Abstract: Combining noble metals with nonnoble metals is an attractive strategy to balance the activity and cost of electrocatalysts. However, a guiding principle for selecting suitable nonnoble metals is still lacking. Herein, a thorough mechanistic study on the platform oxygen evolution reaction (OER) electrocatalyst of Ir@Co 3 O 4 to deeply understand the synergy between Ir and Co 3 O 4 for the boosted OER has been carried out. It is demonstrated that the pseudocapacitive feature of Co 3 O 4 plays a key role in accumulating sufficient positive charge [ Q ], while the Ir sites are responsible for achieving a high reaction order (β), synergistically contributing to the high OER activity of Ir@Co 3 O 4 through the rate law equation. Specifically, Ir@Co 3 O 4 displays a low overpotential of 280 mV at 10 mA cm −2 with a small Ir loading of 1.4 wt%. Ir@Co 3 O 4 is further applied to Zn‐air batteries, which enables a low charging potential and thus alleviates the oxidative corrosion of the air electrode, leading to improved cycle stability of 210 h at 20 mA cm −2 . This work demonstrates that anchoring active noble metal sites (for high β) on pseudocapacitive supports (for high [ Q ]) is highly favorable to the OER process, providing a clear guidance for boosting the utilization of noble metals in electrocatalysis.

Self‐Catalyzed Growth of Co, N‐Codoped CNTs on Carbon‐Encased CoSx Surface: A Noble‐Metal‐Free Bifunctional Oxygen Electrocatalyst for Flexible Solid Zn–Air Batteries
Publisher: Wiley
Date: 15-07-2019
Abstract: The self‐catalyzed growth of nanostructures on material surfaces is one of the most time‐ and cost‐effective ways to design multifunctional catalysts for a wide range of applications. Herein, the use of this technique to develop a multicomponent composite catalyst with CoS x core encapsulated in an ultrathin porous carbon shell entangled with Co, N‐codoped carbon nanotubes is reported. The as‐prepared catalyst has a superior catalytic activity for oxygen evolution and oxygen reduction reactions, an ultralow potential gap of 0.74 V, and outstanding durability, surpassing most previous reports. Such superiority is ascribed, in part, to the unique 3D electrode architecture of the composite, which is favorable for transporting oxygen species and electrons and creates a synergy between the components with different functionalities. Moreover, the flexible solid Zn–air battery assembled with such an air electrode shows a steady discharge voltage plateau of 1.25 V and a round‐trip efficiency of 70% at 1 mA cm −2 . This work presents a simple strategy to design highly efficient bifunctional oxygen electrocatalysts and may pave the way for the practical application of these materials in many energy conversion/storage devices.

Integration of Zn–Ag and Zn–Air Batteries: A Hybrid Battery with the Advantages of Both
Publisher: American Chemical Society (ACS)
Date: 04-10-2018
Abstract: We report a hybrid battery that integrates a Zn-Ag battery and a Zn-air battery to utilize the unique advantages of both battery systems. In the positive electrode, Ag nanoparticles couple the discharge behaviors through the two distinct electrochemical systems by working as the active reactant and the effective catalyst in the Zn-Ag and Zn-air reactions, respectively. In the negative electrode, in situ grown Zn particles provide large surface areas and suppress the dendrite, enabling the long-term operating safety. The battery first exhibits two-step voltage plateaus of 1.85 and 1.53 V in the Zn-Ag reaction, after which a voltage plateau of 1.25 V is delivered in the Zn-air reaction, and the specific capacity reaches 800 mAh g

Robust non-Pt noble metal-based nanomaterials for electrocatalytic hydrogen generation

DOI: 10.1063/5.0021578
Abstract: Currently, the electrocatalytic hydrogen evolution reaction (HER) has been a key point of focus for developing sustainable hydrogen economy, but it is h ered by sluggish reaction kinetics. Despite the fact that various non-noble metal-based materials as electrocatalysts toward the HER are gaining considerable attention, noble metal-based nanomaterials (NMNs) for catalyzing the HER still have advantageous features, i.e., wide pH applicability, high intrinsic activity, and good stability. Considering a high chemical similarity to HER-benchmark Pt metals, various non-Pt NMNs with high atom utilization, super efficiency, and durability for HER catalysis are engineered through various structural/electronic tailoring strategies, which has become a significant trend in this research field. Herein, a panoramic review about recent representative efforts and progress in the design of non-Pt NMNs is presented. It first introduces the HER fundamentals and then generally describes the structural and electronic characteristics of non-Pt noble metals matching the HER. Followed on, different tuning strategies for fabricating effective non-Pt NMN catalysts, including composition optimizing by constructing alloys or novel compounds, morphological tuning via decreasing the particle size or designing unique nanostructures, and hybrid engineering as well as crystalline structure/facet controlling, are systemically summarized, with a special focus on the underlying structure–activity relationship for different catalysts. The features of pH universality and bifunctionality for these non-Pt NMN catalysts are also highlighted. At the end, existing challenges and future perspectives awaiting this emerging research field are discussed.
Bigger is Surprisingly Better: Agglomerates of Larger RuP Nanoparticles Outperform Benchmark Pt Nanocatalysts for the Hydrogen Evolution Reaction
Publisher: Wiley
Date: 21-08-2018
Abstract: Although metallic ruthenium (Ru) is a potential electrocatalyst for the hydrogen evolution reaction (HER) to replace platinum (Pt) at a cost of only ≈4% of Pt, the persistent dissolution of Ru under operation conditions remains a challenge. Here, it is reported that agglomerates of large ruthenium phosphide (RuP) particles (L-RP, ≈32 nm) show outstanding HER performance in pH-universal electrolytes, which particularly demonstrates a surprisingly higher intrinsic activity and durability than small nanoparticles of RuP (S-RP, ≈3 nm) or metallic Ru on carbon supports. This is especially true in basic media, achieving electrocatalytic activity comparable to or even outperforming that of Pt/C, as reflected by lower overpotential at 10 mA cm

Rational design of spinel oxides as bifunctional oxygen electrocatalysts for rechargeable Zn-air batteries
Publisher: AIP Publishing
Date: 19-11-2020
DOI: 10.1063/5.0017398
Abstract: Rechargeable (secondary) zinc-air batteries (ZABs) are a highly attractive type of electrochemical energy storage device with high theoretical energy density, an outstanding safety record, and low cost. The performance of ZABs strongly depends on the development of bifunctional electrocatalysts toward oxygen reduction reaction (ORR) and oxygen evolution reaction (OER). Spinel oxides (AB2O4) have received particular attention because of their high chemical stability under operation conditions, rich raw materials, and compositional flexibility, which provides le room for the design of spinel-structured oxides for ORR/OER catalysis. Many spinel oxides have been successfully applied as air cathodes in ZABs, but the related research is rather scattered. In this review paper, we will provide an in-time comprehensive review of the recent advances in the development of spinel oxides as ORR/OER electrocatalysts and their particular application as air electrodes in rechargeable ZABs. First, we will introduce the electrochemical fundamentals of OER and ORR on spinel oxides and the key factors determining their activity. Then, we will present the activity regulation strategies of spinel oxides and the performance of rechargeable ZABs using spinel-based air cathodes. Finally, we will highlight the current challenges and future developing directions of spinel-based air cathodes. This review could inspire further mechanistic study of the ORR/OER catalysis on spinel oxides and the development of high-performance air cathodes.
