AgCl(Ag)/CuFexTix+1Oy for photocatalytic reduction of nitrate
A photocatalyst AgCl(Ag)/CuFexTix+1Oywere prepared by synthetic methods including solvothermal and chemical precipitation methods.The analysis revealed that the presence of AgCl(Ag)facilitated the generation of photogenerated electrons in CuFexTix+1Oy,while inhibiting the recombination of electrons and holes,consequently enhancing photocatalytic efficiency.This article took nitrate as the removal object and investigated the photoreduction capabilities of the composite materials in the UV/formic acid system as well as their potential application in realistic water.The experimental results indicated that the optimal outcome was achieved when the AgCl doping concentration was 40%by massand the ratio of copper,iron,and titanium was 1:2:3.After 150 minutes of reaction,the nitrate removal rate was 94.6%,the degradation rate reached(0.0188±0.0017)min-1,and the nitrogen conversion rate reached 99.0%.Additionally,in implementation in realistic water treatments,the system exhibited nitrate removal rates of 87.4%for tap water and 80.9%for simulated groundwater,with a nitrogen conversion rate exceeding 70%.These results suggesting a promising potential for application.
