| Abstract Scope |
Niobium pentoxide (Nb2O5) is a promising photocatalyst due to its chemical stability, acidity, band gap, and electronic properties. This work aims to investigate the potential enhancements in photocatalytic activity and visible light absorption through heterostructure formation with CuBi2O4. The literature suggests that heterostructure formation may modulate electronic structure, reduce electron–hole recombination, and improve light absorption in the visible region. At present, experimental efforts are focused on synthesizing Nb2O5:CuBi2O4 via microwave assisted hydrothermal route, followed by structural, optical, and morphological characterization using techniques such as XRD, UV–Vis DRS, Raman and SEM. Preliminary observations are guiding optimization of synthesis parameters. Photocatalytic performance tests under visible light irradiation and antimicrobial activity tests are currently underway. This study seeks to contribute insights into the role of CuBi2O4 in tailoring the photocatalytic properties of Nb2O5, with a view toward applications in environmental remediation and solar driven processes. |
