Problems solved by technology

More importantly, activated carbon and other materials rely on physical adsorption, which is not selective and difficult to regenerate. Often, after adsorbing pollutants, they will desorb after a certain ambient temperature changes, resulting in secondary pollution.
A known titanium dioxide photocatalytic material has problems such as low photocatalytic efficiency and photocatalytic effect only under ultraviolet light conditions.

Abstract

The invention relates to the field of environmental protection, in particular to a preparation method for a non-photocatalytic material for purifying polluting gas. The preparation method for the non-photocatalytic material for purifying the polluting gas has the advantages that the non-photocatalytic material for purifying polluting the gas has a very large specific surface area, pores are composed of modified metal phthalocyanine and dispersion design of deionized powder, and the pore size is adjustable; the catalyst composited in the inner and outer pores can achieve high-efficiency regeneration of the catalyst without a light source; the overall posture of the catalytic material has extremely strong plasticity, is easy to regenerate and has high additional value; the toxic and harmfulpolluting gas can be adsorbed immediately and enters internal active positions when being adsorbed, and the catalytic oxidation reaction occurs to generate harmless carbon dioxide and water.

Description

technical field [0001] The invention relates to the field of environmental protection, in particular to a method for preparing a non-photocatalytic material for purifying polluting gases. Background technique [0002] Air pollution in confined spaces (such as chess and card rooms, car interiors, confined spaces, etc.), mainly polluting gases (such as formaldehyde, volatile organic compounds (VOCs), sulfur (SO2, H2S), nitrogen (NO2) and other odors Pollutants released by a variety of interior decoration materials can even last for several years. The problem of indoor environmental pollution has always been concerned by people. [0003] CN105561749A provides a method for comprehensive treatment of indoor environmental pollution, which includes the following steps: 1) closing doors and windows; 2) spraying VOC stabilized liquid on the indoor ground once every half hour, and applying it 2 to 5 times in total; 3) spraying every half hour Put the formaldehyde treatment solution c...
