【摘要】 本文在对新型TiO2的光、电性质和形貌学研究基础上,首次提出"可见光‘全’分解水的类纳PEC电池模型",将水的redox反应分别放在新型TiO2纳米管内、外表面上进行。模型还提出以合适电化学性质的可变价金属氧化物作为放氧催化剂,表面晶格氧参与放O2过程,克服"全"光解水中四电子转移放O2的困难。此模型期望更多同行进行探索、验证。更多还原

【Abstract】 A nano photoelectrochemical(PEC)cell-like model for visible-light-responded over-all splitting of water was proposed based on the investigation of the photo-electric properties and morphology of the novel TiO2.In this model,the reduction and oxidation of water proceeds on the inner and outer surface of novel TiO2 nanotubes,respectively.The variable-valence metal oxide with suitable electrochemical properties could be used as the water oxidation catalyst,and its surface lattice oxygen would take part in O2 evolution.The difficulty of overall water splitting,i.e.,evolving of O2 while needs to transfer four electrons,might be overcome.We want that this nano PEC cell-like model will be explored and verified by colleagues in the future.更多还原
