摘要
为提高传统单一光催化剂对印染废水的降解效率,采用静电自组装和离子交换方法制备了g-C_(3)N_(4)/MXene/Ag_(3)PO_(4)复合光催化剂。通过SEM、FTIR对制备的催化剂进行表征,并将其用于对活性红195的降解,着重研究了复合催化剂和g-C_(3)N_(4)对活性红195的降解效率。结果表明,该催化剂可在60 min内,对活性红195染料的降解率达到93.61%,其具备优异的重复利用性能,5次复用后,降解率仅下降了10.4%。实验同时探究了催化剂的光催化降解机理。
In order to improve the degradation efficiency of traditional single photocatalyst for printing and dyeing wastewater,g-C_(3)N_(4)/mxene/Ag_(3)PO_(4)composite photocatalyst was prepared by electrostatic self-assembly and ion exchange.The prepared catalyst was characterized by SEM and FTIR and used to degrade active red 195.The degradation efficiency of active red 195 by composite catalyst and g-C_(3)N_(4)was studied.The results showed that the degradation rate of reactive red 195 dye could reach 93.61%within 60 min;It has excellent reuse performance.After five times of reuse,the degradation rate is only reduced by 10.4%.The photocatalytic degradation mechanism of the catalyst was also explored.
