Abstract

The invention discloses a protein inorganic hybrid nano material, a preparation method of the nano material, a catalyst taking the nano material as the carrier, and a preparation method of the catalyst. The protein inorganic hybrid nano material is in a flower shape and is prepared by hybridizing metal phosphate and protein. The provided protein inorganic hybrid nano material has a structured stereo structure, strong structural stability, and large specific surface area. The nano material can be used as a catalyst carrier, the catalytic active components can be evenly precipitated on the surface of hybridized nano material, thus the disperse degree of the catalytic active components is increased, the contact surface between the catalytic active components and the reactants is enlarged, so the catalytic efficiency of unit mass active component is improved, and the catalytic effect of the catalyst is improved. The catalytic performance (If / Ib) of a catalyst, which is prepared by loading Pt on the provided nano material, can reach 6.81, when the catalyst is used to catalyze degradation reactions of methanol, the maximal ECSA of the catalyst can reach 185 m2 / g, and the catalytic effect is prominently improved.

Description

technical field [0001] The invention belongs to the technical field of catalyst materials, in particular to a protein-inorganic hybrid nanomaterial, a preparation method of a protein-inorganic hybrid nanomaterial, a catalyst using the material as a carrier, and a preparation method thereof. Background technique [0002] The catalyst carrier, also known as the support, is one of the components of the supported catalyst; the catalytically active components are supported on the surface of the carrier, and the carrier is mainly used to support the active components, so that the prepared catalyst has specific properties, size and characteristics. Physical properties such as mechanical strength are required to meet the operating requirements of industrial reactors, while the carrier itself generally does not have catalytic activity. [0003] The catalyst carrier can disperse the active components on the surface of the carrier, obtain a higher specific surface area, and improve the...
