Influence of Calcination Temperature on Photocatalyst Performances of Floral Bi2O3/TiO2 Composite

Heterojunction photocatalytic materials show excellent performance in degrading toxic pollutants. This study investigates the influence of calcination temperature on performances floral Bi2O3/TiO2 composite photocatalyst crystal, which was prepared with glycerol, bismuth nitrate, and titanium tetrachloride as major raw via solvothermal method. XRD, SEM/TEM, BET, Uv-vis, XPS were employed to analyze crystal structure, morphology, specific surface area, band gap, chemical structure calcined catalysts. The catalytic photocatalysis tested rhodamine B (RhB) degradation object. results revealed high activity higher catalyst. efficiency catalyst RhB 97%, 100%, 91% at 400 °C, 450 500 °C temperatures, respectively, peak appeared °C. characterization that appropriate promoted crystallization catalyst, increased its area active sites reaction, improved separation electrons holes.
