Abstract

The invention discloses a preparation method of ceramic fiber paper coated with a titanium-boron oxide coating on the surface and belongs to the field of environmental purification materials. The method comprises the steps as follows: synthesis of a titanium-boron liquid: synthesizing the titanium-boron liquid from absolute ethyl alcohol, glycerin, n-butyl alcohol, n-butyl titanate and isopropyl borate through stirring and oscillation; oscillation coating: coating the surface of the ceramic fiber paper with the titanium-boron liquid through oscillation; surface gelatinization: immersing the ceramic fiber paper in a transparent liquid consisting of absolute ethyl alcohol, deionized water and sodium bicarbonate, taking out the ceramic fiber paper and placing the ceramic fiber vertically until gel forms on the surface; film forming by curing: performing drying and calcination to prepare the ceramic fiber paper coated with the titanium-boron oxide coating on the surface. The method is suitable for photocatalytic pollution purification processes in multiple forms.

Description

technical field [0001] The invention belongs to the field of environmental pollution purification materials, in particular to a preparation method of ceramic fiber paper coated with a titanium boron oxide coating on the surface. Background technique [0002] Photocatalytic pollution purification technology has been used in different scales of air and water pollution treatment processes. The most important research hotspot in this field is photocatalytic materials with high activity. Among the various materials that can be used for pollutant purification, titanium-containing oxides are the most important class. In order to supplement the deficiency of pure titanium oxide, composite oxide materials of titanium and other elements can be synthesized, among which boron-containing titanium oxide has a more obvious effect of promoting activity. Due to the complexity of the actual pollution control process, there are various requirements for the performance of photocatalytic mater...
