Study of photocatalysts for hydrogen production through photocatalytic steam reforming of methane at ambient temperature

我们发现了一种可以利用太阳能的甲烷光催化水蒸气重整制氢技术(PSRM)，可以利用水和甲烷作为可再生资源。为了开发用于PSRM的活性光催化剂，我们考察了一些光催化剂，发现了一些设计催化剂和反应体系的指导原则：(1)适合于表面中间体形成的反应条件，(2)具有较少缺陷和高比表面积的半导体颗粒，(3)适合于半导体的掺杂和表面修饰，(4)半导体表面与助催化剂纳米颗粒之间的上帝连接，(5)可能的双功能助催化剂，以及(6)热加速。

We found a photocatalytic steam reforming of methane(PSRM) to produce hydrogen from water and methane as renewable resources, which can utilize solar energy. To develop active photocatalysts for the PSRM, we examined some photocatalysts and found several guidelines for the design of catalyst and the reaction system :(1) reaction condition suitable for the formation of surface intermediates,(2) semiconductor particles having less defects and high specific surface area,(3) doping and surface modification suitable for the semiconductors,(4) god junction between the semiconductor surface and the cocatalyst nanoparticles,(5) possible bifunctional cocatalyst, and(6) thermal acceleration.
