titleOfInvention | A kind of biomass-based metal single-atom-nitrogen-carbon catalyst and its preparation method and application |
abstract | The invention discloses a biomass-based metal single-atom-nitrogen-carbon catalyst and a preparation method and application thereof, including: (1) biomass wall breaking grinding: breaking biomass with a plant protein content of not less than 10% wall grinding to obtain a biomass colloidal solution; (2) mixing biomass and non-precious metal salts: adding non-precious metal salts to the biomass colloidal solution, and mixing to obtain a mixed precursor colloidal solution; (3) spray pyrolysis: mixing The mixed precursor colloidal solution is sprayed and pyrolyzed to obtain catalyst powder; (4) Pickling: the catalyst powder is acid-washed with an acid solution to prepare a biomass-based metal single-atom-nitrogen-carbon catalyst. The method of the invention can realize the preparation of high-dispersion, high-load biomass-based metal single-atom-nitrogen-carbon catalyst, has simple process, low cost, environmental friendliness, small and uniform catalyst powder size, and can be used as a proton exchange membrane fuel cell catalyst for the cathodic oxygen reduction reaction. |
