摘要:
光催化降解染料废水作为安全的、环境友好的技术越来越受世人关注,但目前研究制备的光催化剂仍存在性能不稳定且难以高效再生等亟待解决的难题.基于此,以聚合紫罗碱(polyviologens,PV)和磷钼酸(H3PMo12O40,HPMo)为原料合成了磷钼酸-聚合紫罗碱(PMo-PV)复合材料,并将其作为载体负载Ag/AgBr催化剂,用于光催化降解甲基橙染料.由该法制备的Ag/AgBr/PMo-PV催化剂具有较高的比表面积和丰富的介孔结构,在光催化降解甲基橙反应中活性优于Ag/AgBr催化剂和商业TiO2 P25催化剂,而且该催化剂在含有H2O2条件下多次重复反应后仍保持着很高的活性,其重复稳定性远大于Ag/AgBr催化剂.
Abstract:
Photocatalytic degradation of dyes wastewater as a safe and environmentally friendly technology has attracted worldwide attention.However,currently there is still lack of photocatalysts that can be efficiently regenerated with stable performance.In this study,the polyviologen(PV)and phosphomolybdic acid(HPMo)composite PMo-PV was designed and synthesized as the Ag/AgBr catalyst for photocatalytic degradation of methyl orange dyes.The prepared Ag/AgBr/PMo-PV with high surface area and abundant porous structure showed its high photocatalytic activity,better than the Ag/AgBr and commercial TiO2 P25 catalysts.Furthermore,in the presence of H2O2,Ag/AgBr/PMo-PV catalyst remained high catalytic activity after repeated catalytic reactions and also showed much better reproducibility than the Ag/AgBr catalyst.
