Catalyst with hydrogen storage performance, preparation method and application thereof

Abstract

The invention belongs to the field of catalysts, and in particular relates to a catalyst with hydrogen storage performance and a preparation method and application thereof. The catalyst with hydrogen storage performance includes the following components: a metal hydrogen storage material and a metal boride; the mass ratio of the metal hydrogen storage material to the metal boride is 10-5:1. The catalyst of the present application and gaseous H 2 Reversible reactions occur to form metal solid solutions and metal hydrides. When the hydrogen molecule contacts the surface of the alloy, it is first adsorbed on the surface of the alloy molecule, and then the H-H bond dissociates to become hydrogen in the atomic state. The hydrogen in the atomic state reduces the hexafluoroacetone to hexafluoroisopropanol under the action of the hydrogenation catalyst. . The catalyst of the invention can be reacted under mild conditions, and has low requirements for reaction equipment; the catalyst of the invention has high catalytic activity and high selectivity, and almost no by-products are generated.

Description

technical field

[0001] The invention belongs to the field of catalysts, and in particular relates to a catalyst with hydrogen storage performance and a preparation method and application thereof. Background technique

[0002] Hexafluoroisopropanol (CF 3 CHOHCF 3 , referred to as HFIP) is an important fluorine-containing intermediate, which can be used to prepare high-end fluorine-containing fine chemicals such as anesthetics and surfactants. Due to its strong polarity, HFIP is miscible with water and many organic reagents, heat-resistant and allows the passage of ultraviolet light, these properties make it an ideal solvent for many polymer systems, including polyamide, polyester, polyacrylonitrile, polyamide Universal solvent for polymer systems of acetal and hydrolyzed polyvinyl esters.

[0003] The synthesis method of hexafluoroisopropanol is mainly a hydrogenation reduction method using hexafluoroacetone as a raw material. According to the different reducing agents, it...
