Abstract

The invention provides a preparation method of a biomass-derived porous carbon confinement monatomic metal composite material, which comprises the following steps: mixing a biomass raw material dispersion liquid with phthalocyanine and metal phthalocyanine in a conjugate manner, and carrying out high-temperature pyrolysis in an inert gas atmosphere to obtain the biomass-derived porous carbon confinement monatomic metal composite material. Compared with the prior art, the method has the advantages that cheap biomass waste is used as a carbon and nitrogen source, phthalocyanine is used as a nitrogen source, metal phthalocyanine is used as a metal source, steric hindrance is provided for metal atoms by means of coordination of phthalocyanine / metal phthalocyanine, the method can be universally applied to preparation of various metal monatomic catalytic materials, and the metal monatomic is uniform in dispersion and excellent in performance.

Description

technical field

[0001] The invention relates to a preparation method of a biomass-derived porous carbon-confined single-atom metal composite material, which belongs to the research field of single-atom catalytic technology and utilization of biomass waste resources. Background technique

[0002] The metal in the single-atom catalytic material is dispersed on the carrier at the atomic level, with the smallest size, high atom utilization rate and excellent catalytic activity. It can be used in carbon monoxide oxidation, carbon dioxide reduction, oxygen reduction reaction (ORR), hydrogen evolution reaction (HER) , Nitrogen Reduction Reaction (NRR), methane reforming hydrogen production and organic synthesis and other catalytic fields, which show comparable or better activity and selectivity than traditional homogeneous catalysts, and at the same time have the advantage of easy separation of heterogeneous catalysts. Emerging research hotspots in the field of heterogeneous cataly...
