Abstract

The invention provides a preparation method and application of a nano-catalyst for efficiently treating trimethylamine polluted gas, and belongs to the technical field of odor pollutant treatment andgas phase pollution control. A stainless steel wire is selected as a conductive substrate, a conductive cathode loaded with a Co-MoS2 catalyst is prepared, a catalytic reaction membrane assembly is composed of the conductive cathode and conductive metal anode immersed in 0.5mol / L of a K2SO4 electrolyte solution, the polluted gas in a reactor is removed. According to the preparation method, photoelectro-catalytic technology is combined, under the action of bias voltage, photo-generated charge carriers are driven to different directions, recombination of electrons and holes is effectively inhibited, and the catalyzing efficiency of the catalyst is improved. The preparation method of the nano-catalyst has the beneficial effects that the synthesized Co-MoS2 composite catalyst is evenly dispersed in petal shapes, trimethylamine can be removed in a short time through the photoelectrochemistry synergistic effect, and the purpose of air purifying is achieved.

Description

technical field

[0001] The invention belongs to the technical field of malodorous gas treatment, and provides a petal-shaped Co-MoS that efficiently removes trimethylamine malodorous gas in the air 2 Composite materials, coupled with the bias potential generated by metal corrosion, construct a photoelectric coupling catalytic system, which improves the photocatalytic efficiency. The catalyst has a high removal rate of trimethylamine, a stable effect, and is applicable to a wide range of pollutant concentrations. Background technique

[0002] As we all know, malodorous pollutants are a kind of special odorous gases, which refer to all gaseous substances that stimulate the olfactory organs, cause people's unpleasantness and damage the living environment. It is a typical nuisance pollution and is also the focus of current complaints. Trimethylamine is a colorless, toxic, flammable simple organic amine gas that produces an unpleasant and pungent ammonia and fishy odor. It is ...
