摘要

II-VI半导体的表面空位已被确认为光催化CO2还原的活性位点。本文以量子限制的CdS纳米棒为模型光催化剂，研究了阴离子空位与光催化CO2还原性能之间的关系。在电子结构变化方面，具有更多表面S空位的CdS纳米棒具有更高的CO生成率，这是通过后处理故意引入S空位来证实的。

Anion vacancy correlated photocatalytic CO2 to CO conversion over quantum-confined CdS nanorods under visible light†

Surface vacancies in II–VI semiconductors have been confirmed as active sites for photocatalytic CO₂ reduction. Here we take quantum-confined CdS nanorod as a model photocatalyst to correlate anion vacancies with photocatalytic CO₂ reduction performance. In terms of electronic structure change, CdS nanorods with more surface S vacancies give enhanced CO generation rates, which were confirmed by deliberately introducing S vacancies via a post-treatment.
