Abstract

The invention discloses an Ag/AgCl loaded sodium nickel phosphate composite photocatalytic material as well as a preparation method and application thereof. The chemical formula of a base material of the composite photocatalyst is Na4Ni3P4O15; and particles Ag and AgCl are loaded on the surface of the base material. The preparation method comprises the following steps: firstly, preparing the base material by adopting a high-temperature solid-phase method or a chemical solution method; then, mixing and dispersing obtained Na4Ni3P4O15 powder and AgNO3 powder; and carrying out precipitation-photoreduction treatment to finally obtain the Ag/AgCl/Na4Ni3P4O15 composite photocatalyst. The photocatalytic material has a relatively good photocatalytic effect and the preparation method is simple to operate and feasible and low in production cost; and industrial production is facilitated and organic pollutants can be degraded very well.

Description

technical field [0001] The invention relates to an Ag / AgCl loaded sodium nickel phosphate composite photocatalytic material and a preparation method and application thereof, which are especially suitable for degrading organic pollutants and belong to the field of inorganic photocatalytic materials. Background technique [0002] Since the 21st century, with the continuous development of human society, while people's living standards have been continuously improved, the negative impacts have also been brought about, such as the waste and pollution of water resources, making people have to pay attention to this problem, so water bodies Pollution control has become one of the problems that people urgently need to solve. [0003] The photocatalytic reaction is a chemical reaction in which light, catalysts and substances exist and interact simultaneously, and the core of which is the photocatalytic material. Its catalytic mechanism is that after the catalyst is irradiated by ligh...
