摘要
构建异质结是实现高效电荷分离、提高光催化性能的有效策略。在这里，我们介绍了一种 0D/3D S 型异质结 BiOBr/Bi7O9I3，它是通过在 Bi7O9I3 纳米花表面加入高度分散的 BiOBr 量子点（QDs）而构建的。这种异质结构能有效吸收可见光，并通过 S 型途径显著增强电荷载流子的分离。因此，BiOBr/Bi7O9I3 光催化剂表现出卓越的光催化 O2 演化率，达到近 1500 μmol h-1 g-1。这项工作凸显了构建 S 型异质结以提高光催化 O2 演化的有效性。
Constructing a heterojunction is an effective strategy to achieve high-efficiency separation of charges, which enhances the photocatalytic performance. Here, we present a 0D/3D S-scheme heterojunction, BiOBr/Bi7O9I3, which was constructed by incorporating highly dispersed BiOBr quantum dots (QDs) onto the surface of Bi7O9I3 nanoflowers. This heterostructure effectively absorbs visible light and enhances the separation of charge carriers significantly via an S-scheme pathway. As a result, the BiOBr/Bi7O9I3 photocatalysts demonstrated an excellent photocatalytic O2 evolution rate, achieving a rate of nearly 1500 μmol h−1 g−1. This work highlights the effectiveness of constructing S-scheme heterojunctions to enhance photocatalytic O2 evolution.
