Abstract
We report the improvement of photocatalytic proton reduction using molecular polyoxovanadate-alkoxide clusters as hole scavengers for CdSe quantum dots. The increased hydrogen production is explained by favorable charge interactions between reduced forms of the cluster and the charge on the quantum dots arising from the capping ligands.
摘要
我们报道了使用分子聚氧钒酸盐 - 醇盐簇作为CdSe量子点的空穴清除剂来改善光催化质子还原。氢气产量的增加是由簇的还原形式与由封端配体产生的量子点上的电荷之间的有利电荷相互作用来解释的。
