Abstract

The invention relates to a method for preparing a reticular gadolinium titanium oxide material. The method comprises the following steps of: preparing a precursor solution 1: using absolute ethyl alcohol, acetone, pentanediol, stabilizing agents, tetra-n-butyl titanate, surfactants and guiding agents for preparation through heating and backflow; preparing a precursor solution 2: using deionized water, citric acid, gadolinium nitrate, sodium carbonate, polyethylene glycol 10000 and glacial acetic acid for preparation; preparing sol: mixing two precursor solutions, and then performing heating and backflow; performing coating decoration by titanium net gel: lifting and pulling a titanium net in a sol for preparation; performing heat treatment: drying and calcining the titanium net coated with the sol. The stability of a gadolinium titanium oxide coating is high; the active ingredient distribution of the gadolinium titanium oxide is uniform; the catalyst activity is high.

Description

technical field [0001] The invention belongs to the field of environmental purification functional materials, and in particular relates to a method for preparing a netted gadolinium titanate material. Background technique [0002] After nearly 50 years of research and development, photocatalytic pollution purification technology has gradually become a potential multi-purpose pollution purification method, and has excellent applications and performances in various aspects of industry and civil use. In order to improve the efficiency of photocatalytic purification, an important aspect is the use of highly efficient and special-purpose catalytic materials. Industrial photocatalytic purification reactors often have special requirements on the shape of materials, and pure powder materials cannot meet the continuous purification process of pollutants. In order to avoid the separation step from the photocatalytic material after sewage treatment, supported materials are often use...
