摘要：
Photocatalytic carbon dioxide conversion technology can not only use inexhaustible solar energy, but also convert carbon dioxide into high-value-added carbon-based fuels, which has attracted extensive attention from researchers. Herein, we designed and fabricated the Co3O4/CdIn2S4 heterojunction photocatalyst with hollow structure to convert CO2. With series of measurement, the results show that the efficient coupling of the two materials could greatly promote photo-generated carriers separation and press the recombination of that, meanwhile, the introduction of MOFs template could help catalyst to expose more active sites. Based on the above unique advantages and compared to the pure CdIn2S4, the 5% Co3O4/CdIn2S4 heterojunction performs well in whole photocatalytic reduction process, which can generate the CO. And CO generation rate could be up to 74 μmol•g-1•h-1 and selectivity could be 100%. © All Right Reserved.
