Abstract

2D MoS₂/BiOBr van der Waals heterojunctions can be used for photoelectrocatalytic hydrogen production. The Cover Feature shows a MoS₂/BiOBr heterojunction working as a photocathode. The photogenerated electrons from BiOBr mainly flow into two directions: one is migrating towards the MoS₂ surface, driving the hydrogen evolution reaction; the other is accumulating on BiOBr and reduces BiOBr to metallic Bi. However, in a heterojunction with small ratio of MoS₂, the electrons are prone to transfer to MoS₂, thus decreasing the accumulation of electrons on BiOBr and preventing it from deactivation. More information can be found in the Research Article by Mengjiao Wang, Francesco Lamberti, and co-workers (DOI: 10.1002/cctc.202400282).

封面专题：通过范德华异质结策略稳定层状生物硼光电催化剂（ChemCatChem 16/2024）

二维 MoS2/BiOBr 范德华异质结可用于光电催化制氢。封面特写展示了一个用作光电阴极的 MoS2/BiOBr 异质结。来自 BiOBr 的光生电子主要流向两个方向：一个流向 MoS2 表面，推动氢进化反应；另一个积聚在 BiOBr 上，将 BiOBr 还原成金属 Bi。然而，在 MoS2 比例较小的异质结中，电子容易转移到 MoS2 上，从而减少电子在 BiOBr 上的积累，防止其失活。更多信息，请参阅王梦蛟、Francesco Lamberti 及合作者的研究文章（DOI: 10.1002/cctc.202400282）。

期刊介绍： With an impact factor of 4.495 (2018), ChemCatChem is one of the premier journals in the field of catalysis. The journal provides primary research papers and critical secondary information on heterogeneous, homogeneous and bio- and nanocatalysis. The journal is well placed to strengthen cross-communication within between these communities. Its authors and readers come from academia, the chemical industry, and government laboratories across the world. It is published on behalf of Chemistry Europe, an association of 16 European chemical societies, and is supported by the German Catalysis Society.
