中文摘要:
      在光催化全分解水产氢的过程中,Pt等助催化剂在催化产生氢的同时也会诱导催化氢气和氧气重新复合为水的逆反应,严重降低了悬浮体系光催化全分解水产氢的效率.我们综述了近年来在逆反应抑制方面的研究进展,总结和对比分析了各种抑制逆反应策略的特点,并对将这些方法应用于悬浮体系光催化全分解水制氢的前景进行了展望.
英文摘要:
      In the process of photocatalytic overall water splitting, the cocatalysts such as Pt were used to catalyze the hydrogen evolution reaction. However, they can also catalyze the hydrogen and oxygen recombination reverse reaction into water, which result in the low photocatalytic efficiency for H2 generation in suspension system. In this work, the research progress on the inhibition of reverse reaction in recent years has been reviewed. The characteristics of various strategies of inhibiting reverse reaction were summarized and compared. The prospects of these methods for the photocatalytic overall water splitting to generate hydrogen in suspension system were prospected.
