Photoelectrochemical reduction of CO(2) to HCOO(-) (formate) over p-type InP/Ru complex polymer hybrid photocatalyst was highly enhanced by introducing an anchoring complex into the polymer. By functionally combining the hybrid photocatalyst with TiO(2) for water oxidation, selective photoreduction of CO(2) to HCOO(-) was achieved in aqueous media, in which H(2)O was used as both an electron donor and a proton source. The so-called Z-scheme (or two-step photoexcitation) system operated with no external electrical bias. The selectivity for HCOO(-) production was >70%, and the conversion efficiency of solar energy to chemical energy was 0.03-0.04%.
在 p 型 InP/Ru 配合物聚合物杂化光催化剂中引入锚固配合物，可显著增强 CO(2)光电还原为 HCOO(-)(甲酸盐)的性能。通过将杂化光催化剂与 TiO(2)功能结合以促进水氧化，在水相介质中实现了 CO(2)的选择性光电还原为 HCOO(-)，其中 H(2)O 既作为电子供体又作为质子源。该所谓的 Z 型(或两步光激发)体系在没有外部电偏压的情况下运行。HCOO(-)生成的选择性大于 70%，太阳能到化学能的转化效率为 0.03-0.04%。
