Silver Nanoparticles Incorporated pH-Responsive Nano-Hybrid Catalytic System for the Reductive Decolorization of Industrial dyes |
| 초록 |
In recent years, industrial dyes pose great threat to the environment. Their hazardous effects mostly carcinogenicity demands the need of a proper degradation method. Reduction has been proved to be an efficient strategy for the removal these contaminants from wastewater. Herein, a pH-responsive poly (methacrylic acid) functionalized SBA-15 was synthesized via free radical polymerization and then incorporated with silver nanoparticle. The resultant AgNPs-SBA-15-PMAA catalyst was applied for the reduction of various industrial dyes using NaBH4 as the reducing agent. Compared to any other synthesized catalysts, AgNPs-SBA-15-PMAA showed higher activity for the reduction of various anionic dyes. The effects of pH, concentration of AgNO3 and NaBH4 were also studied in detail. The catalyst was successfully recovered and could be reused without obvious losses of catalytic activity. Our present study suggest that the catalytic system can be used for wastewater treatment |
