Abstract

Efficient solar water photosplitting is plagued by large overpotentials of the HER and OER. Even with a noble metal catalyst, the hydrogen evolution reaction can be limited by the strong M-H bonding over some metals, such as Pt, Pd, and Rh, inhibiting hydrogen desorption. H absorption is regulated by the potential at the metal nanoparticles. Through controlled periodic illumination of a Pt/TiO suspension, we hypothesized a fast variation of the photopotential that induced catalytic surface resonance on the metal, resulting in more than a 50% increase of the efficiency at frequencies higher than 80 Hz.

摘要

高效的太阳能光解水受到析氢反应（HER）和析氧反应（OER）的大过电位的困扰。即使使用贵金属催化剂，析氢反应在某些金属（如铂、钯和铑）上也可能受到强M-H键的限制，从而抑制氢的解吸。氢的吸收受金属纳米颗粒处电位的调节。通过对Pt/TiO悬浮液进行受控的周期性光照，我们推测光电位的快速变化会在金属上诱导催化表面共振，从而在高于80 Hz的频率下使效率提高超过50%。
