摘要
太阳能光热催化水分解制氢为解决能源短缺和环境污染问题提供了极具前景的技术路径。然而受到半导体吸收光谱和光生载流子复合等问题的制约,光热催化水分解制氢的太阳能转换效率仍有很大的提升空间。负载助催化剂是提升催化性能的有效策略。本文通过热熔融盐法制备了掺杂Al的SrTiO_(3)载体,随后通过光沉积法在载体上负载了不同种类的助催化剂,通过水分解光热催化实验和一系列表征分别说明了Rh、Cr、Co助催化剂的作用。
Solar photothermal catalyzed hydrogen production from water decomposition provides a promising way to solve the problems of energy shortage and environmental pollution.However,due to the constraints of semiconductor absorption spectra and photogenerated carrier composites,the solar energy conversion efficiency of photothermal catalyzed hydrogen production from water decomposition still has much room for improvement.Among them,enhancing catalytic performance by loading co-catalysts is a very promising solution.In this paper,Al-doped SrTiO_(3) carriers were prepared by hot molten salt method,and then different kinds of co-catalysts were loaded on the carriers by photodeposition method,and the roles of Rh,Cr,and Co co-catalysts were illustrated respectively by hydrolysis photothermal catalytic experiments and a series of characterizations.
