Document Type and Number:
WIPO Patent Application WO/2023/060778
Kind Code:
A1
Abstract:
Provided are an amphiphobic platinum-containing catalyst material, a preparation method therefor and the use thereof. The method comprises the following steps: constructing a plurality of silicon hydroxyl groups on a surface; growing nano silicon dioxide particles on the surface by using a mixed solution containing a silicate ester compound, a silicate ester hydrolysis catalyst and water under the condition of 20ºC-30ºC; carrying out an activating treatment by utilizing an amino silane coupling agent solution under the condition of 20ºC-30ºC; under the condition of 20ºC-30ºC, carrying out a functionalization treatment by utilizing a solution containing an aryl silane compound and a fluoroalkyl silane compound to obtain an amphiphobic porous substrate material; and growing nano platinum particles on the surface of the amphiphobic porous substrate material to obtain an amphiphobic platinum-containing catalyst material. The amphiphobic platinum-containing catalyst prepared by the preparation method provided in the present invention also has hydrophobic and oleophobic properties, shows good hydrogen isotope catalytic oxidation performance at room temperature, and also has good restart performance and service life.
