可见光响应型改性纳米二氧化钛催化降解生物质气化洗焦废水
摘要：摘要制备了可见光响应型改性纳米二氧化钛催化剂，用于处理生物质气化洗焦废水，考察了催化剂改性方式对苯酚和洗焦废水COD去除的影响。实验结果表明：以Ag-C/TiO2为催化剂，在可见光下照射10 h，苯酚的COD去除率可达43.5%，洗焦废水的COD去除率达26.8%；在太阳光下照射36 h，洗焦废水的COD去除率达到90.9%。改性纳米Ag-C/TiO2催化剂在可见光下具有良好的催化活性，对洗焦废水有较好的处理效果。

Abstract:：Modified nano-TiO2 catalysts were prepared and used for photocatalytic degradation of biomass gasification waste water under visible light. The effects of modification methods on COD removal of phenol and waste water were investigated. After irradiation under visible light for 10 h in the presence of Ag-C/TiO2, the COD removal of phenol was 43.5%, and the COD removal of the waste water was 26.8%. When exposed under sunlight for 36 h, the COD removal of the waste water reached 90.9%. The modified Ag-C/TiO2 exhibited high photocatalytic activity under visible light, and good capability to degrade the biomass gasification waste water.
