Embodiment Construction

[0022] This invention is a kind of Cu x Ag (1-x) / (Cu y Ag (1-y) ) 2 O / Ag 3 PO 4 / TiO 2 New photocatalytic material, 0 2 Modified Cu on Nanowires x Ag (1-x) , (Cu y Ag (1-y) ) 2 O nanoparticles and clumpy Ag 3 PO 4 Get, where Cu x Ag (1-x) The diameter of the particles is 10-50nm, (Cu y Ag (1-y) ) 2 The diameter of O particles is 5-20nm, Agglomerate 3 PO 4 The diameter is 50-200nm.

[0023] A kind of Cu x Ag (1-x) / (Cu y Ag (1-y) ) 2 O / Ag 3 PO 4 / TiO 2 The preparation method of the novel photocatalytic material includes the following steps:

[0024] (1) Nano TiO 2 Because of its stable chemical properties, non-toxicity, and strong ability to absorb ultraviolet rays, it is often used as a photocatalytic material. The invention first prepares TiO on the surface of the titanium sheet 2 Nanowires; the preparation method can be: putting a 2.5cm×2.5cm titanium sheet into acetone, ultrasonicating for 15min, and then ultrasonicating with deionized water for 5min. Put the processed titanium...

Abstract

The invention discloses a novel photocatalytic material based on Cu and Ag. The material can be expressed by CuxAg(1-x) / (CuyAg(1-y))2O / Ag3PO4 / TiO2, wherein 0<x and y<=1. Based on the preparation of TiO2 nanowires by a hydrothermal method, the novel photocatalytic material CuxAg(1-x) / (CuyAg(1-y))2O / Ag3PO4 / TiO2 with a large specific surface area is obtained by modifying CuxAg(1-x), (CuyAg(1-y))2O nanoparticles and bulk Ag3PO4. The novel photocatalytic material has good photocatalytic performance.

Description

Technical field [0001] The invention belongs to the technical field of preparation of novel photocatalytic materials, and particularly relates to a novel photocatalytic material based on Cu and Ag. x Ag (1-x) / (Cu y Ag (1-y) ) 2 O / Ag 3 PO 4 / TiO 2 And preparation method. Background technique [0002] With the development of industry, humans' already limited water resources are increasingly polluted. The removal of toxic and harmful chemicals in water bodies, such as halogenated hydrocarbons, pesticides, and surfactants, has become an important task in the field of environmental protection. According to the changing characteristics of pollutants in the treatment process, wastewater treatment can be divided into three types, namely separation treatment, conversion treatment and dilution treatment. Separation treatment only transfers pollutants from one phase to another, and cannot completely decompose or harmless pollutants. Some methods still have the problem of secondary pollutio...
