Abstract

The invention discloses a ruthenium catalyst capable of efficiently catalyzing decomposing of formic acid for preparing hydrogen, and belongs to the technical field of energy source catalysis materials and hydrogen preparation. The invention mainly relates to preparation of the efficient catalyst and the process of catalyzing decomposition of formic acid by applying the catalyst. An optimum catalyst turnover number (TON) is obtained by reasonably controlling the reaction temperature, catalyst solvents, additives and other factors in the decomposition process of formic acid. The catalyst has the TON value larger than 1.8 million under an optimum reaction condition. The catalyst is capable of catalyzing formic acid for preparing hydrogen under a normal-temperature condition, and obtained hydrogen is directly applicable to chemical synthesis, fuel cells, engines and the like.

Description

technical field

[0001] The invention belongs to the technical fields of energy catalytic materials and hydrogen production, and relates to the preparation of a catalytic system derived from a metal ruthenium salt and a Pincer-like ligand complex, preferably the conditions for the catalyst to catalyze the dehydrogenation of formic acid to obtain hydrogen. Background technique

[0002] As a highly chemically active and widely used substance, hydrogen occupies an important position in the fields of national production and scientific research. At the same time, with the excessive utilization of mineral energy such as oil, natural gas, and coal, hydrogen is regarded as an efficient and clean energy substitute. However, the utilization of hydrogen is currently facing three major problems: a large amount of cheap hydrogen production; safe and convenient storage and transportation; extensive and economical application forms, etc.

[0003] In recent years, the rapid development of f...
