【摘要】 利用可见光催化催化还原CO₂是解决环境问题和能源需求的一种有前景的途径。我们最近首次利用钙钛矿结构的纳米立方CoSn（OH）₆成功实现CO₂还原制取CO,同时开发了多个高效光催化二氧化碳还原体系。^[1,2]我们将在报告中详细汇报本课题组在这一领域的研究进展。更多还原

【Abstract】 A perovskite hydroxide CoSn（OH）₆ nano particle was developed and used for the first time on photocatalytic reduction of CO₂. Under mild photocatalytic reaction condition, the photocatalytic efficiency is extremely high(193000 μmol.g^-1) for CO generation with Ru（bpy）₃（PF₆）₂ as photosensitizer. In our photocatalysis system, weak Br?nsted acids, as another important factor, were used as proton sources to improve the photocatalytic activity and CO selectivity.更多还原
