Photocatalytic oxidation of organic compounds proceeded efficiently in a hybrid system with ruthenium aqua complexes as catalysts, BiVO4 as a light absorber, Co(NH3)5Cl as a sacrificial electron acceptor and water as an oxygen source. The photogenerated holes in the semiconductor are used to oxidize molecular catalysts into the high-valent Ru(IV)=O intermediates for 2e(-) oxidation.
在一个混合体系中，以钌水配合物为催化剂、BiVO₄为光吸收剂、Co(NH₃)₅Cl为牺牲电子受体且水为氧源，有机化合物的光催化氧化反应能高效进行。半导体中的光生空穴用于将分子催化剂氧化成用于2e(-)氧化的高价Ru(IV)=O中间体。
