Abstract

The present disclosure provides a near-infrared (NIR) photothermal catalyst and a preparation method and use thereof. The method includes: mixing a graphene oxide (GO) dispersion and a dehydrating agent to obtain a GO solution; mixing the GO solution and branched polyethyleneimine (PEI) and then drying to obtain a GO-PEI carrier; and mixing the GO-PEI carrier with water and adjusting a pH value to be within a range of 2 to 4.5, adding dropwise a monosubstituted Keggin-type polyoxometalate (POM) aqueous solution, and conducting an ion replacement reaction to obtain the NIR photothermal catalyst, wherein a solute of the monosubstituted Keggin-type POM aqueous solution is K6SiW11Co(H2O)O39 or H4SiW11Ce(H2O)4O39.
