周世雄 ZSX

摘要


Cu和graphene作为助催化剂之间的协同作用,能有效地接受和传输半导体导带上的电子,抑制电荷复合,提高界面电荷转移过程,提供更好的吸附位点和光催化反应中心,能有效的提高光催化产氢.Cu和Graphene同时是廉价的,对环境无害的材料,且容易制备.该研究为我们提供了利用非贵金属助催化剂捕获太阳能有效分解水产氢的新思路和新方法.
Cu and graphene as the synergy between the cocatalyst can effectively accept and transfer semiconductor conduction band electronic, suppress charge recombination, improve interfacial charge transfer process, provide better adsorption sites and photocatalytic reaction centers can effectively improve the photocatalytic hydrogen production activity. The Cu and graphene simultaneously is inexpensive, environmentally harmless materials, and easy preparation. The research provides us with new ideas and new ways of using nonprecious metal cocatalysts capture solar energy effective decomposition of hydrogen production.
