摘要

封面特写描绘了 Cu@Cr2O3/TiO2 等离子光催化剂以及在可见光照射下工作的热电子和正空穴的电荷分离。在他们的研究文章中,H. Kominami 及其合作者报告说,Cu@Cr2O3/TiO2 核壳粒子中心的部分 Cr2O3(红色和绿松石色球体)已被移除,以显示内部的铜纳米粒子(橙色球体)。光照射产生的热电子(e-)移动到 TiO2 表面,而正空穴(h+)则留在 Cu@Cr2O3/TiO2 颗粒上。

Cover Feature: Preparation of a Stable Cr2O3/Cu/TiO2 Plasmonic Photocatalyst for Selective Alcohol Oxidation under Visible Light Irradiation (λ>600 nm) (ChemistryEurope 3-4/2024)

A Cu@Cr2O3/TiO2 plasmonic photocatalyst together with charge separation of hot electrons and positive holes working under visible light irradiation is depicted on the cover feature. In their Research Article, H. Kominami and co-workers report that part of Cr2O3 (red and turquoise spheres) has been removed from the Cu@Cr2O3/TiO2 core–shell particle in the center to show the inner Cu nanoparticles (orange spheres). The hot electrons (e) generated by the light irradiation move to the surface of the TiO2, and the positive holes (h+) are left on the Cu@Cr2O3/TiO2 particle.
