摘要
氢能是一种清洁、环保的可再生资源,以其具有较高的燃烧热值和燃烧产物为水等特点而成为取代传统化石燃料的最佳选择,采用绿色清洁的电解水制取氢气成为科研人员关注热点。传统碱性电解水技术中催化剂层多以催化剂浆液滴涂并与粘合剂粘连在电极表面,对三相界面的扩散造成一定的影响,然而,自支撑导电基底可以避免上述问题,活性层与导电基底无缝接触实现了快速的电荷转移,从而提供了高活性电解水催化剂的集成式合成策略。从工业级大电流水电解三相反应界面构筑角度出发,归纳了近年来制备自支撑纳米催化材料的研究进展,并探讨了自支撑纳米催化剂在电解水领域的应用,并对未来制备自支撑电解水催化剂的集成化与工业化进行了展望。
Hydrogen energy is a clean,environmentally friendly renewable resource,which is the best choice to replace traditional fossil fuels because of its high calorific value of combustion and combustion products as water,etc.The use of green and clean water electrolysis to produce hydrogen has become a hot topic of interest for researchers.In conventional alkaline water electrolysis technology,the catalyst layer is mostly coated with catalyst ink and adhered to the electrode surface with adhesive,which has certain impact on the diffusion at the three-phase interface.However,the self-supported conductive substrate can avoid the above problems,and the active layer is in seamless contact with the conductive substrate to achieve rapid charge transfer,thus providing an integrated synthesis strategy for highly active water electrolysis catalysts.The research progress of preparing self-supported nanocatalytic materials in recent years from the perspective of three-phase reaction interface construction for industrial-grade high-current water electrolysis was summarized,and the application of self-supported nanocatalysts in the field of water electrolysis was discussed,and a prospect on the integration and industrialization of preparing self-supported water electrolysis catalysts in the future was provided.
