Copper bismuth oxide (CuBi2O4): Synthesis, properties and potential applications

Abstract

CuBi₂O₄ is a p-type semiconductor which is an outstanding representative of the spinel-type compounds. In the present article, various methods used for the synthesis of CuBi₂O₄ such as hydrothermal, co-precipitation, microwave-assisted, mechanochemical, solid-state etc. with the feature(s) of the product obtained have been summarized. Also, the studies reviewed have revealed that CuBi₂O₄ has been used as a photocatalyst, as a photocathode material, in gas sensing applications, in activating certain oxidants such as Peroxymonosulfate and H₂O₂, and for various other applications.
