Abstract

The invention relates to a synthesizing method of a net-shaped Ag / Ag3PO4 / AgCl (silver / silver phosphate / silver chloride) composite photocatalysis material. The synthesizing method is characterized bycomprising the following steps of sequentially putting a silver net into a mixed solution of diluted nitric acid, phosphoric acid and hydrochloric acid with certain concentration, soaking, fetching out the silver net, cleaning by deionized water, and blow-drying by nitrogen, so as to obtain the net-shaped Ag / Ag3PO4 / AgCl composite photocatalysis material. The synthesized net-shaped Ag / Ag3PO4 / AgCl composite photocatalysis material can be applied to the fields of degrading of vapor-phase and liquid-phase organic pollutants by photocatalysis and the like, and have the advantages that the technology is simple and convenient; the industrialized production is easy to realize.

Description

technical field [0001] The invention relates to a network Ag / Ag 3 PO 4 The invention discloses a synthesis method of / AgCl composite photocatalytic material, which belongs to the field of inorganic non-metallic materials. Background technique [0002] Photocatalytic materials generate hole-electron pairs by absorbing light, and then generate active species to perform photochemical reactions. They are mainly used to degrade organic pollutants, CO 2 Catalytic reduction, water splitting hydrogen production and other fields. In this research background, in 2010, the Japanese National Institute of Material Science reported the superior visible light catalytic activity of silver phosphate, both in the degradation of organic pollutants and water splitting tests, the catalytic activity is much higher than the existing Photocatalyst. [0003] Subsequently, researchers carried out a lot of research around silver phosphate. Wang Yunfang published "Ag / Ag 3 PO 4 Preparation of Comp...
