Microwave assisted hydrothermal synthesis of Ag2O/α-Bi2O3 heterostructures with highly enhanced photocatalysis and their environmental interest

Abstract

A methodological analysis is made in the rational synthesis of the Ag2O/α-Bi2O3, p-n junction heterostructure with significant application, possessing substantial electron-hole recombination acting as solar catalysts through powerful and modest microwave inspired hydrothermal technique. Meanwhile, Ag2O/α-Bi2O3 is intermediary for single step Methyl Red (MR) dye photocatalytic degradation. Additionally, the experimental and characterization findings demonstrated that sunlight-induced surface effects on synthetic materials remove heavy metals such as Lead (Pb) sunder solar irradiation. The research work provides a strategy for excellent and efficient design of photocatalyst as an eco-friendly and biomedical approach. Electrochemical studies, such as photocurrent calculations, band positions and EIS for Ag2O/α-Bi2O3 heterostructures were also carried out. The study helps to broaden the search for and development of new hybrid composites for electrochemical applications and environmental interest.
