Special Issue Information

Dear Colleagues,

Since the groundbreaking work published by Honda and Fujishima in the 1960s on the electrochemical photolysis of water, the use of Metal Oxide Semiconductors in Photocatalysis has gained enormous attention, giving rise to a broad scope of applications. Although the potential of metal oxides semiconductors as catalytic platforms in organic synthesis was demonstrated decades later, efficient photocatalytic systems are being developed in order to achieve light‐induced high‐valuable organic transformations. Their unique (and tunable) electronic, optical, and chemical properties make them an attractive and powerful tool for solar to chemical energy conversion. In this line, the photocatalytic potential of metal oxide semiconductors has been demonstrated in a variety of applications ranging from energy harvesting systems to degradation of pollutants. Moreover, their low cost, abundance, low toxicity, chemical stability, and heterogeneous nature represent a greener and efficient alternative to transition metals‐based complexes and organic compounds.

This Special Issue aims to cover the application of Metal Oxide Semiconductors in Photocatalysis, especially to organic transformations such as C–C, C–heteroatom bond formation, and oxidations and reductions processes, as well as their use in continuous flow technology.

Therefore, we welcome your contributions to the field in the form of research articles, communications, or short reviews that reflect the state of the research of the proposed topic.

Abstract
Plasmonic Au-ZnO hybrids with adjustable structures (including Au-decorated ZnO and core–shell Au@ZnO with dense and porous ZnO shells) and the optimized hot electron-driven photocatalytic activity were successfully prepared.

Plasmonic Au-ZnO hybrids with adjustable structures (including Au-decorated ZnO and core–shell Au@ZnO with dense and porous ZnO shells) and the optimized hot electron-driven photocatalytic activity were successfully prepared. It was found that the Au@ZnO core–shell hybrids with porous morphology had the highest plasmon-enhanced photocatalytic hydrogen generation activity under visible light irradiation. The wavelength-dependent photocatalytic tests verified that Au@ZnO with porous ZnO shells had the highest apparent quantum efficiency upon resonance excitation. The ultrafast transient absorption measurements revealed that Au@ZnO with porous ZnO shells had the fastest plasmon-induced hot electron injection, which was thought to be the reason for the improved photocatalytic activity. This work might provide a promising route to designing photocatalytic and photoelectric materials. Full article
