The invention relates to a titanium dioxide-modified activated carbon-supported silver single-atom catalyst and its application in the oxidation of formaldehyde, comprising three steps: pretreatment of activated carbon, preparation of titanium dioxide-modified activated carbon carrier and preparation of titanium dioxide-modified activated carbon-supported silver single-atom , to obtain a titanium dioxide-modified activated carbon-supported silver single-atom catalyst. Compared with the prior art, the present invention uses titanium dioxide-modified activated carbon as a carrier, and the silver single-atom morphology features are uniform and regular, and has good catalytic performance and stability to formaldehyde at room temperature, and the preparation process is simple, suitable for industrial Chemical production has high economic value. |
