PREPARATION METHOD FOR NOBLE METAL-LOADED POROUS ORGANIC FRAMEWORK ATOMIC-SCALE CATALYST FOR CATALYTIC DEGRADATION OF VOCS AT ROOM TEMPERATURE

摘要

A preparation method for a noble metal-loaded porous organic framework atomic-scale catalyst for the catalytic degradation of VOCs at room temperature, comprising the steps of: (a) preparing a carrier: adding 2,6-diaminopyridine and 1,3,5-benzenetricarbonyl trichloride into a dichloromethane solution containing triethylamine, stirring well, putting the formed solution into an oil bath pot and heating for reaction to obtain a porous organic framework containing a pyridine-amide functional group; (b) dipping to load a noble metal: completely dipping the pyridine-amide porous organic framework into a noble metal salt solution, carrying out ultrasonic treatment and letting stand, then adding a sodium borohydride solution to reduce the noble metal, washing and drying to obtain a noble metal-loaded pyridine-amide porous organic framework atomic-scale active site catalyst semi-finished product; and (c) calcining: placing the semi-finished product in a muffle furnace and calcining, and obtaining a finished product after calcination is complete. The described catalyst has high atom dispersity and may form atomic-scale active sites, thus catalytic efficiency is greatly improved.
