从催化剂的结构出发，研究了NiO ∶ SrTiO 3光催化分解H2 O生成H2和O2的反应机理。阐明了NiO上发生H2析出，而SrTiO 3上发生O2析出。NiO和SrTiO 3之间的界面的Ni金属的存在的重要性，建议两种材料之间的电子转移。讨论了单光子过程和双光子过程两种可能的机制。
The mechanism of the photocatalytic decomposition of H2O into H2and O2over NiOSrTiO3powder was studied on the basis of the structure of the catalyst. It was elucidated that H2evolution occurs over NiO while O2evolution takes place over SrTiO3. The importance of the existence of Ni metal between the interface of NiO and SrTiO3suggested the transfer of an electron between both materials. Two possible mechanisms, a one-photon process and a two-photon process, were discussed.
