Preparation of electron-withdrawing group phthalocyanine/bismuth halide oxides composite catalyst and its photocatalytic degradation of pollutants in water

Key Points

• Photocatalytic degradation of pollutants shows significant efficiency under visible light irradiation, enabling effective treatment.
• The composite catalyst combines phthalocyanine with bismuth halide oxides, enhancing its photocatalytic properties for pollutant removal.
• Preparation involved synthesizing an electron-withdrawing group into the catalyst structure to improve its activity significantly.
• Utilizing this composite could lead to more effective water purification methods against various environmental contaminants.
