要旨

Hydrogen energy, with the advantages of being pollution-free and having high combustion efficiency and a high utilization rate, has been widely developed as a substitute for traditional fossil fuels. The hydrogen evolution reaction (HER) plays an important role in water electrolysis. Metal-free electrocatalysts show the advantages of abundant reserves, tunable molecular structure and high tolerance to extreme pH conditions compared with metal-based catalysts. With the significant progress made in the discovery of novel metal-free HER catalysts, some of them can break through our knowledge limitations and demonstrate enormous industrial potential. In this review, the fabrication methods of metal-free catalysts are first introduced to provide readers with a general understanding of the synthesis procedures. Then, some important types of metal-free catalysts are discussed in detail. Finally, clues for obtaining high-performance HER metal-free catalysts and possible future research directions and prospects are provided. This review can accelerate the development of novel metal-free HER catalysts in related applications.

Journal of Materials Chemistry A, B & C cover high quality studies across all fields of materials chemistry. The journals focus on those theoretical or experimental studies that report new understanding, applications, properties and synthesis of materials. The journals have a strong history of publishing quality reports of interest to interdisciplinary communities and providing an efficient and rigorous service through peer review and publication. The journals are led by an international team of Editors-in-Chief and Associate Editors who are all active researchers in their fields. Journal of Materials Chemistry A, B & C are separated by the intended application of the material studied. Broadly, applications in energy and sustainability are of interest to Journal of Materials Chemistry A, applications in biology and medicine are of interest to Journal of Materials Chemistry B, and applications in optical, magnetic and electronic devices are of interest to Journal of Materials Chemistry C. More than one Journal of Materials Chemistry journal may be suitable for certain fields and researchers are encouraged to submit their paper to the journal that they feel best fits for their particular article. Example topic areas within the scope of Journal of Materials Chemistry A are listed below. This list is neither exhaustive nor exclusive. Artificial photosynthesis Batteries Carbon dioxide conversion Catalysis Fuel cells Gas capture/separation/storage Green/sustainable materials Hydrogen generation Hydrogen storage Photocatalysis Photovoltaics Self-cleaning materials Self-healing materials Sensors Supercapacitors Thermoelectrics Water splitting Water treatment
