Abstract

The invention discloses a preparation method of a halloysite loaded indium phosphate catalyst. The preparation method comprises the following steps: acidizing halloysite, dissolving an aluminum oxide structure of halloysite to be favorable for loading; adding the processed halloysite into an indium chloride solution, adding an ammonium phosphate solution dropwise so as to cover a colloid on the surface of the halloysite, finally centrifuging, separating, washing and drying to obtain the halloysite loaded indium phosphate catalyst. The adsorption action between the uneven surface of the halloysite and an indium phosphate colloid particle is utilized, an indium phosphate nanoparticle is loaded on the surface of the halloysite, and the fixing of the catalyst is promoted.

Description

technical field [0001] The invention relates to the technical field of new materials for environmental pollution control, in particular to a method for preparing a halloysite-loaded indium phosphate catalyst. Background technique [0002] With the development of science and technology, toxic organic pollutants from industrial and agricultural production seriously threaten the environment and human health. It is of great significance to seek a new and efficient environmental governance technology. Photocatalytic technology has become an emerging environmental treatment technology with important application prospects due to its advantages of energy saving, high efficiency, complete pollutant degradation, and no secondary pollution. In recent years, the development of new and efficient visible light photocatalysts has become an important research content in photocatalytic technology. Among them, photocatalytic materials with surface plasmon resonance effect, because of their un...
