摘要
氢能被公认为未来最有前景的能源之一,电解水析氢技术作为一种绿色、高效、可持续的制氢方法备受关注。疏松多孔的聚苯胺作为催化剂载体、模板或纳米掺杂颗粒与具有低析氢过电压、高电流密度的金属或金属化合物催化剂相结合,能有效增大活性比表面积、增加活性位点、提供导电通道,从而降低金属催化剂的析氢过电位,提高电解水析氢活性。综述了近年来聚苯胺修饰金属催化剂在电解水析氢领域的发展动态,指出电解水析氢负载型催化剂替代贵金属催化剂是未来重要的研究方向。
Hydrogen energy has been recognized as one of the most promising future energy sources.As a green,efficient and sustainable pathway of hydrogen production,water electrolysis has been favored.Loose and porous polyaniline,which was selected as catalyst carrier,template or doped nanoparticles of metal or metallic compound catalyst charactered by low hydrogen overpotential and high current density,can effectively enlarge the active surface area,increased the active sites and provided conductive channels.These supported catalysts,which can lower hydrogen overpotential and promoted the water electrolysis hydrogen evolution activity,was introduced.The developments of polyaniline modified metal catalyst in water electrolysis hydrogen field in recent years were reviewed with detail.Replacing noble metal catalyst with supported catalyst became an important research direction in the future.
