Abstract: Photoelectrochemical (PEC) water splitting is recognized as a sustainable strategy for hydrogen generation due to its abundant hydrogen source, utilization of inexhaustible solar energy, high‐purity product, and environment‐friendly process. To actualize a practical PEC water splitting, it is paramount to develop efficient, stable, safe, and low‐cost photoelectrode materials. Recently, graphitic carbon nitride (g‐C 3 N 4 ) has aroused a great interest in the new generation photoelectrode materials because of its unique features, such as suitable band structure for water splitting, a certain range of visible light absorption, nontoxicity, and good stability. Some inherent defects of g‐C 3 N 4 , however, seriously impair further improvement on PEC performance, including low electronic conductivity, high recombination rate of photogenerated charges, and limited visible light absorption at long wavelength range. Construction of g‐C 3 N 4 ‐based nanosized heteroarrays as photoelectrodes has been regarded as a promising strategy to circumvent these inherent limitations and achieve the high‐performance PEC water splitting due to the accelerated exciton separation and the reduced combination of photogenerated electrons/holes. Herein, we summarize in detail the latest progress of g‐C 3 N 4 ‐based nanosized heteroarrays in PEC water‐splitting photoelectrodes. Firstly, the unique advantages of this type of photoelectrodes, including the highly ordered nanoarray architectures and the heterojunctions, are highlighted. Then, different g‐C 3 N 4 ‐based nanosized heteroarrays are comprehensively discussed, in terms of their fabrication methods, PEC capacities, and mechanisms, etc. To conclude, the key challenges and possible solutions for future development on g‐C 3 N 4 ‐based nanosized heteroarray photoelectrodes are discussed.

Abstract: The adsorption behaviors and mechanism of geopolymers based on metakaolin-fly ash for Sr 2+ , Co 2+ and Cs + were investigated in static method. The results showed that the geopolymer has a strong adsorbability for Sr 2+ , Co 2+ and Cs + and the adsorbances are mainly affected by ion concentration and pH value of the solution. The adsorption dynamic model of the material for Sr 2+ , Co 2+ and Cs + is confirmed to be the first-order reaction and the adsorption isotherm curves showed that the adsorption behaviors belong to monolayer adsorption which is simulated by the Langmuir model very well. Desorption of Sr 2+ , Co 2+ and Cs + could be carried on by immersing the adsorbents in the solutions with low pH or high ionic strength solution. Desorption experiments and XRD analysis indicate that the adsorption behaviors of geopolymer for the three kinds of ions are mainly chemical adsorption, according to the ion-exchange mechanism.

Abstract: Supercapacitors have been regarded as promising power supplies for future electronics due to their high power density, superior stability, easy integration, and safety. Extrusion‐based three‐dimensional printing technologies hold promise to satisfy the demands for integrated and flexible supercapacitors because of their highly versatile manufacturing process. In this review article, a comprehensive and timely review of these state‐of‐the‐art technologies is presented. We start with a brief introduction of fundamental concepts of supercapacitors, including energy storage mechanisms and device structures. Then, the latest progress of extrusion‐based three‐dimensional printing technologies (e.g., fused deposition modeling, inkjet printing, and direct ink writing) along with their applications for manufacturing supercapacitors is summarized. The choice of printable materials (e.g., graphene, carbon nanotubes, metal oxides, and MXenes), printing process, and the resulted electrochemical performances of supercapacitors are especially emphasized. Finally, the development of extrusion‐based three‐dimensional printing supercapacitors is summarized, with existing challenges diagnosed, possible solutions proposed, and future outlooks forecasted. We hope this review can offer insights to further improve the performance of three‐dimensional‐printed supercapacitors for practical applications.

Abstract: As a clean and renewable energy source, solar energy is a competitive alternative to replace conventional fossil fuels. Nevertheless, its serious fluctuating nature usually leads to a poor alignment with the actual energy demand. To solve this problem, the direct solar‐to‐electrochemical energy conversion and storage have been regarded as a feasible strategy. In this context, the development of high‐performance integrated devices based on solar energy conversion parts (i.e., solar cells or photoelectrodes) and electrochemical energy storage units (i.e., rechargeable batteries or supercapacitors [SCs]) has become increasingly necessary and urgent, in which carbon and carbon‐based functional materials play a fundamental role in determining their energy conversion/storage performances. Herein, we summarize the latest progress on these integrated devices for solar electricity energy conversion and storage, with special emphasis on the critical role of carbon‐based functional materials. First, principles of integrated devices are introduced, especially roles of carbon‐based materials in these hybrid energy devices. Then, two major types of important integrated devices, including photovoltaic and photoelectrochemical‐rechargeable batteries or SCs, are discussed in detail. Finally, key challenges and opportunities in the future development are also discussed. By this review, we hope to pave an avenue toward the development of stable and efficient devices for solar energy conversion and storage.

Abstract: Direct methanol fuel cells (DMFCs) are among the most promising portable power supplies because of their unique advantages, including high energy density/mobility of liquid fuels, low working temperature, and low emission of pollutants. Various metal-based anode catalysts have been extensively studied and utilized for the essential methanol oxidation reaction (MOR) due to their superior electrocatalytic performance. At present, especially with the rapid advance of nanotechnology, enormous efforts have been exerted to further enhance the catalytic performance and minimize the use of precious metals. Constructing multicomponent metal-based nanocatalysts with precisely designed structures can achieve this goal by providing highly tunable compositional and structural characteristics, which is promising for the modification and optimization of their related electrochemical properties. The recent advances of metal-based electrocatalytic materials with rationally designed nanostructures and chemistries for MOR in DMFCs are highlighted and summarized herein. The effects of the well-defined nanoarchitectures on the improved electrochemical properties of the catalysts are illustrated. Finally, conclusive perspectives are provided on the opportunities and challenges for further refining the nanostructure of metal-based catalysts and improving electrocatalytic performance, as well as the commercial viability.

Abstract: Present mobile devices, transportation tools, and renewable energy technologies are more dependent on newly developed battery chemistries than ever before. Intrinsic properties, such as safety, high energy density, and cheapness, are the main objectives of rechargeable batteries that have driven their overall technological progress over the past several decades. Unfortunately, it is extremely hard to achieve all these merits simultaneously at present. Alternatively, exploration of the most suitable batteries to meet the specific requirements of an in idual application tends to be a more reasonable and easier choice now and in the near future. Based on this concept, here, a range of promising alternatives to lithium-sulfur batteries that are constructed with non-Li metal anodes (e.g., Na, K, Mg, Ca, and Al) and sulfur cathodes are discussed. The systems governed by these new chemistries offer high versatility in meeting the specific requirements of various applications, which is directly linked with the broad choice in battery chemistries, materials, and systems. Herein, the operating principles, materials, and remaining issues for each targeted battery characteristics are comprehensively reviewed. By doing so, it is hoped that their design strategies are illustrated and light is shed on the future exploration of new metal-sulfur batteries and advanced materials.
