Abstract: Research into efficient synthesis, fundamental properties, and potential applications of phosphorene is currently the subject of intense investigation. Herein, solution-processed phosphorene or few-layer black phosphorus (FL-BP) sheets are prepared using a microwave exfoliation method and used in photoelectrochemical cells. Based on experimental and theoretical (DFT) studies, the FL-BP sheets are found to act as catalytically active sites and show excellent electrocatalytic activity for triiodide reduction in dye-sensitized solar cells. Importantly, the device fabricated based on the newly designed cobalt sulfide (CoS

Abstract: 2D materials have shown great promise in various applications including solar cells, but their use as light‐harvesting active layers in photovoltaic (PV) devices is limited. Herein, surface‐oxidized antimonene sheets are prepared using a liquid‐phase exfoliation method and employed as an active light absorber material after functionalization. It is shown that 2D antimonene possesses unique surface chemistry that allows it to form photoactive Sb 2 S 3 light absorbers for solar cells under ambient conditions. Under the standard PV testing conditions (AM1.5G), devices fabricated with 2D antimonene‐based light‐harvesting materials deliver a power conversion efficiency (PCE) of up to 4.28%. This novel type of solar cell exhibits outstanding operational stabilities, preserving % of the initial PCE after aging for 60 min at a temperature of 85 °C, retaining % of the initial efficiency after exposure to continuous light illumination under 1 sun for 180 min, and maintaining its functionality after being underwater for 25 min. This work opens new avenues for research in 2D materials and photovoltaics.

Abstract: Graphene and related elemental 2D materials have become core materials in nanotechnology and shown great promise for industrially important electrocatalysis reactions. Although excellent progress has been made over the past few years, research into the field of elemental 2D materials beyond graphene is still at an early stage. Importantly, recent research has revealed the promising efficacy of elemental 2D materials as effective nitrogen reduction reaction (NRR) electrocatalysts due to their many excellent properties including high surface activities, acting as active sites for effective functionalization and defect engineering. This review provides a comprehensive account of recent advances in elemental 2D materials with a major focus on the solution‐based synthesis routes and their applications in electrocatalytic NRR for ammonia (NH 3 ) production. After a concise overview of elemental 2D materials, the advantages and challenges of currently available methods for the synthesis of these 2D materials are discussed. Then, the review focuses on the use of these emerging 2D materials in the electrocatalytic reduction of N 2 for sustainable (NH 3 ) synthesis. Finally, the challenges still to be addressed, and important perspectives in this attractive field are emphasized.

Abstract: Carbon nanotubes are 1D nanocarbons with excellent properties and have been extensively used in various electronic and optoelectronic device applications including solar cells. Herein, we report a significant enhancement in the efficiency and stability of perovskite solar cells (PSCs) by employing single-walled carbon nanotubes (SWCNTs) in the mesoporous photoelectrode. It was found that SWCNTs provide both rapid electron transfer and advantageously shifts the conduction band minimum of the TiO

Abstract: 2D‐layered materials have attracted increasing attention as low‐cost supports for developing active catalysts for the hydrogen evolution reaction (HER). In addition, atomically thin Ti 3 C 2 T x (MXene) nanosheets have surface termination groups (T x : F, O, and OH), which are active sites for effective functionalization. In this work, heteroatom (boron)‐doped Ti 3 C 2 T x (MXene) nanosheets are developed as an efficient solid support to host ultrasmall ruthenium (Ru) nanoparticles for electrocatalytic HER. The quantum‐mechanical first‐principles calculations and electrochemical tests reveal that the B‐doping onto 2D MXene nanosheets can largely improve the intermediate H* adsorption kinetics and reduce the charge‐transfer resistance toward the HER, leading to increased reactivity of active sites and favorable electrode kinetics. Importantly, the newly designed electrocatalyst based on Ru nanoparticles supported on B‐doped MXene (Ru@B–Ti 3 C 2 T x ) nanosheets shows a remarkable catalytic activity with low overpotentials of 62.9 and 276.9 mV to drive 10 and 100 mA cm −2 , respectively, for the HER, while exhibiting excellent cycling stabilities. Moreover, according to the theoretical calculations, Ru@B–Ti 3 C 2 T x exhibits a near‐zero value of Gibbs free energy (Δ G H* = 0.002 eV) for the HER. This work introduces a facile strategy to functionalize MXene for use as a solid support for efficient electrocatalysts.

Abstract: Phosphorene, a single- or few-layered semiconductor material obtained from black phosphorus, has recently been introduced as a new member of the family of two-dimensional (2D) layered materials. Since its discovery, phosphorene has attracted significant attention, and due to its unique properties, is a promising material for many applications including transistors, batteries and photovoltaics (PV). However, based on the current progress in phosphorene production, it is clear that a lot remains to be explored before this material can be used for these applications. After providing a comprehensive overview of recent advancements in phosphorene synthesis, advantages and challenges of the currently available methods for phosphorene production are discussed. An overview of the research progress in the use of phosphorene for a wide range of applications is presented, with a focus on enabling important roles that phosphorene would play in next-generation PV cells. Roadmaps that have the potential to address some of the challenges in phosphorene research are examined because it is clear that the unprecedented chemical, physical and electronic properties of phosphorene and phosphorene-based materials are suitable for various applications, including photovoltaics.
