Common methods for removing formaldehyde mainly include catalytic oxidation, activated carbon adsorption, plasma high temperature, and photocatalysis. This thesis uses catalytic oxidation to remove formaldehyde, a method that utilizes the ability of catalysts to activate oxygen to completely convert formaldehyde into non-toxic and harmless CO2 and H2O. In this paper, two types of catalysts, noble metal catalysts (Pt/C3N4) and non-noble metal catalysts (Co-Nx/C), were prepared for the catalytic oxidation of formaldehyde, and their effects were explored through a series of characterization methods. The mechanism and reaction mechanism provide research directions and ideas for efficient purification of formaldehyde at room temperature. The main research contents and results of this paper are as follows:
