摘要:
用湿化学沉淀法将Ag3PO4沉积在活性炭纤维（ACF）上制备复合光催化剂Ag3PO4/ACF，采用BET比表面积法和扫描电子显微镜分析对样品进行表征，通过在可见光下降解橙II检测样品的光催化活性。结果表明，Ag3PO4/ACF的光催化活性比纯Ag3PO4提高了32%，主要是Ag3PO4/ACF具有更为精细的Ag3PO4晶体束，且分布更均匀，对污染物的吸附能力增强以及Ag3PO4与ACF有紧密的接触界面。Ag3PO4/ACF对橙II的降解率随着投加量的增大而提高，最佳投加量为1 000mg/L。随着染料初始pH的增大，Ag3PO4/ACF对橙II的降解率逐渐下降，强酸环境较有利于降解染料废水。在Ag3PO4/ACF循环使用4次后，其对橙II的降解率由99%下降到59%。
Abstract:
Ag3PO4/ACF was obtained via the deposition Ag3PO4 on the actived carbon fiber by the wet chemical method.The prepared samples were characterized by Brunauer-Emmett-Teller method and scanning electron microscope (SEM).The photocatalytic activity of samples was evaluated by photocatalytic degradation of Orange II aqueous solutions under visible-light irradiation.The results show that the photocatalytic properties of Ag3PO4/ACF was increased by 32% compared with the pure Ag3PO4,due to the much smaller size and good dispersion of Ag3PO4 immobilizing on ACF, and a higher adsorption capability and a closely contacted interface for Ag3PO4/ACF composites.The decolorization rate of Orange II was increased with the increase of the dosage of Ag3PO4/ACF.The optimum dosage was 1 000mg/L.The degradation rate of Orange II were decreased with the increasing of solution pH, which inferred that Ag3PO4/ACF was more suitable for processing Orange II under strongly acidic conditions.After four cycling run of the photodegradation,the catalytic degradation rate of Ag3PO4 /ACF decrased from 99% to 59%.
