Abstract

The invention discloses a preparation method of a halloysite loading phosphoric acid Silverlight catalyst. The preparation method comprises the following specific steps of adding halloysite in a salpeter solution so as to obtain the halloysite after acid treatment, placing the 4-8g halloysite after acid treatment into a vacuum filtration bottle, mixing the halloysite and a silver nitrate ethanol solution under a vacuum state, enabling the silver nitrate to fully enter a halloysite pipe, sequentially stirring 2-5h, carrying out solid-liquid separation, and vacuum drying at 70-80 DEG C; adding the obtained product after drying in a 50 mL of sodium dihydrogen phosphate solution the concentration of which is 0.5-1.5mol / L, stirring for 4-5h, carrying out solid-liquid separation, washing, drying at 100-105 DEG C so as to obtain the halloysite loading phosphoric acid Silverlight catalyst. The preparation method provided by the invention has the advantages that the air and moisture in a halloysite pipeline are discharged, the silver nitrate enters a pipeline, an aluminum oxide of the inner wall of the halloysite is removed, the effects of increasing light penetrating degree and aperture property action can be achieved, the obtained silver phosphate particles are arranged in a halloysite pipe and are prevented from birdnesting and falling.

Description

Technical field [0001] The invention relates to the field of new materials for environmental pollution control, in particular to the preparation of a halloysite-supported silver phosphate photocatalyst. 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 treatment technology. Because of its advantages of energy saving, high efficiency, thorough degradation of pollutants, and no secondary pollution, photocatalytic technology has become an emerging environmental treatment technology with important application prospects. In recent years, the development of new and efficient visible light photocatalysts has become an important research content in photocatalysis technology. Among them, photocatalytic materials with surface plasmon resonance effect have become a major sou...
