Abstract

The invention discloses a method for synthesizing a titanium-aluminum binary oxide catalyst by a sol-gel method. The method comprises the following steps: 1) preparing a solution system PVP (Polyvinyl Pyrrolidone) solution stabilizer; 2) titanium-aluminum oxide co-precipitation alkali adjustment; (3) crystallizing the titanium-aluminum binary oxide; and 4) collection and characterization of the titanium-aluminum binary oxide. The preparation method disclosed by the invention is simple, and the synthesized binary oxide particles are in a nanometer-to-micrometer level and have smooth surfaces. The titanium-aluminum binary oxide catalyst is successfully synthesized, the catalytic efficiency of the catalyst is expected to be improved, the catalytic cost is reduced, and a new method is provided for preparation and synthesis of a catalyst material. The problem that the catalyst is low in catalytic efficiency at low temperature can be effectively solved, and the catalyst still has high catalytic efficiency at low temperature.

Description

Technical field [0001] The present invention belongs to the field of catalytic materials, and a method of synthesizing titanium-aluminum dibasic oxide catalyst in a sol-gel method. Background technique [0002] In recent years, new high-performance catalysts have been one of the topics in the field of chemical industry. Among them, metal oxides are used as catalysts, which have been fully concerned in various fields due to their excellent performance. Compared to single metal oxides, mixed oxide chemistry and physical properties are better than single metal oxides, so their synthesis and applications are increasingly concerned. [0003] Among them, titanium dioxide is an important n-type semiconductor metal oxide with strong ultraviolet light absorption, high refractive index, and unique electronic properties, widely used in photocatalytic, pigment, and photovoltaic cells. In this field, TiO 2 As an n-type semiconductor, it is possible to adsorb the ultraviolet rays, show value i...
