Silver phosphate,as an ideal photocatalytic material,exhibits extremely high photocatalytic activity in the degradation of ammonia nitrogen in water.Ag3PO4 semiconductor materials were prepared using three methods: egg membrane method,direct precipitation method,and hydrothermal synthesis.The crystal structure and properties of Ag3PO4 were analyzed using X-ray diffraction,scanning electron microscopy,and UV visible spectrophotometer.Photocatalytic degradation experiments were conducted on ammonia nitrogen solution and Rhodamine B dye.The results indicated that the Ag3PO4-Z crystal prepared by direct precipitation method had the best photocatalytic activity among the three methods.The exposure degree of its silver phosphate (110) crystal surface was relatively high,and the oxidation ability of photogenerated electrons generated was stronger.At the same time,the nanoparticle size was smaller,the specific surface area was larger,and it could adsorb more pollutants,which was more conducive to the photocatalytic process.Therefore,by controlling the preparation conditions,the morphology and crystal structure of Ag3PO4 photocatalysts could be regulated,providing valuable insights for promoting the application in industrial wastewater treatment.
