Abstract
The Bi2VO2Se nanocomposite was successfully synthesized by hydrothermal method. The physical and chemical properties of photocatalyst sample were characterized by XRD, SEM, FTIR, UV–Vis spectroscopy. The nanocomposite showed the band-gap (Eg) 2.38 eV. To evaluate the photocatalytic efficiency of a synthesized composite, Congo red (CR) and Methylene blue (MB) dyes were used as organic pollutants. The Bi2VO2Se photocatalyst was found to degrade CR dye with degradation efficiency of 92.7% in 50 min, while MB dye degraded only 38% in 50 min when exposed to direct sunlight. Due to its optimal optical stability and consistency, the Bi2VO2Se photocatalyst might be promoted as a cost-effective photocatalyst for practical uses. The results indicated that suitable optical absorption, better efficiency separation, and decreased electron-hole interaction due to the nanocomposite effect are all factors that contribute to enhanced photocatalytic activity.
