property analysis of β-tetragonal bismite thin films: varied concentrations and enhanced photocatalytic efficiency

In this study, we thoroughly examine β-bi2o3 thin films as potential photocatalysts. we produced these films using an environmentally friendly sol gel method that is also cost-effective. our research focuses on how different precursor concentrations, ranging from 0.1 m to 0.4 m, affect the photocatalytic performance of these films. we conducted a comprehensive set of tests to analyze various aspects of the films, including their structure, morphology, topography, optical properties, wettability, and photocatalytic capabilities. these tests provided us with a well-rounded understanding of the films’ characteristics. to assess their photocatalytic efficiency, we used methylene blue (mb) as a contaminant and found that the films, particularly those with a 0.1 m concentration, achieved an impressive 99.9% degradation of mb within four hours. the 0.1 m film had a crystalline size of 39.7 nm, an indirect band gap of 2.99 ev, and a contact angle of 51.37°. our findings suggest that β-bi2o3 films, especially the 0.1 m variant, have promising potential for treating effluents from complex industrial dye processes. this research marks a significant step in utilizing sustainable materials to address pollution and environmental remediation challenges.
