Porous silicon dioxide gel particles loaded with graphite-phase carbon nitride, paper with porous silicon dioxide gel particles loaded with graphite-phase carbon nitride and production method of porous silicon dioxide gel particles loaded with graphite-phase carbon nitride

Abstract

The invention discloses porous silicon dioxide gel particles loaded with graphite-phase carbon nitride, paper with the porous silicon dioxide gel particles loaded with the graphite-phase carbon nitride and a production method of the porous silicon dioxide gel particles loaded with the graphite-phase carbon nitride, and belongs to the technical field of environmental catalysis. A sol-gel method is adopted for mixing a tetraethoxysilane aqueous solution and g-C3N4 to produce the porous silicon dioxide gel particles loaded with the graphite-phase carbon nitride, the porous silicon dioxide gel particles loaded with the graphite-phase carbon nitride has a large specific surface area, the pore structure size is controllable, and the particle size of an assistant is controllable. Production conditions are mild, the process is simple, the raw materials are cheap, the repeatability is good, and the produced material has good photocatalytic performance. When the porous silicon dioxide gel particles loaded with the graphite-phase carbon nitride are added into decorative materials, the catalytic efficiency of photocatalytic materials can be improved, and the study range of the photocatalytic materials is expanded.

Description

technical field [0001] The invention belongs to the technical field of environmental catalysis, and in particular relates to a porous silicon dioxide gel particle loaded with graphite phase carbon nitride, paper with the same and a preparation method thereof. Background technique [0002] Environmental pollution has become a major problem that our country and the world need to face. Formaldehyde is a colorless gas with a strong pungent smell. Its 37% aqueous solution is called formalin. It is commonly used in medical and scientific research departments. Preservation of specimens. In order to prevent corrosion of interior decoration materials and furniture, wood is also commonly soaked in formaldehyde solution before processing to prevent corrosion and damage by wood borers. The boiling point of formaldehyde is 19.5°C, and it is very volatile at room temperature, and the volatilization speed is accelerated as the temperature rises. It ranks second in my country's priority l...

Problems solved by technology

[0004] Due to the poor air permeability of traditional wallpaper, it is used as a skeleton carrier to disperse g-C 3 N 4 Not only can the overflowing formaldehyde molecules pass through the wallpaper and g-C smoothly 3 N 4 reaction, because the pore structure is blocked by the catalyst, the formaldehyde molecules cannot be released for a long time, and formaldehyde molecules still overflow for several years or even longer

Due to its good pore structure and mechanical strength, the sponge can be used as a good carrier to evenly disperse g-C 3 N 4 Degradation of formaldehyde, but because the pore structure in the sponge is too large and the pore size is too large, most of the formaldehyde molecules are not absorbed by the catalyst when they overflow, and are directly emitted to the room, and the formaldehyde removal effect is not good
