Enhancement of Dye Degradation by Zinc Oxide via Transition-Metal Doping: A Review

Contemporary semiconducting ceramics, including zinc oxide, find applications in a variety of different fields. Its wurtzite crystal structure can accommodate various dopants, allowing extensive engineering to achieve desired properties. Different manufacturing methods such as the sol-gel method, microemulsion technique, chemical vapor deposition (CVD), thermal decomposition, etc. result in different morphologies and yield a range of particle sizes that affect its optical, photocatalytic, and semiconducting properties. Indeed, it has been reported that the introduction of dopants can enhance the dye degradation and photocatalytic properties of ZnO. Graphic Abstract

Automated summary

Contemporary semiconducting ceramics, including zinc oxide, have found applications in various fields due to their wurtzite crystal structure that can accommodate different dopants. Different manufacturing methods give rise to variations in morphology and particle size, affecting optical, photocatalytic, and semiconducting properties. The introduction of dopants can enhance specific properties, such as dye degradation and photocatalysis, of ZnO.
