Catalyst for decomposition of formic acid, method for decomposing formic acid, process for producing hydrogen, apparatus for producing and decomposing formic acid, and method for storing and generating hydrogen

摘要

A catalyst for the decomposition of formic acid including a dinuclear metal complex represented by a formula (1) below, a tautomer or stereoisomer thereof, or any of their salts,; ;where M¹ and M² are transition metals; Ar is a ligand having aromaticity and may be unsubstituted or substituted; R¹ to R²⁷ are each independently a hydrogen atom, an alkyl group, or the like, or R¹⁵ and R¹⁶ may together form a —CH═CH—, where Hs in the —CH═CH— may be each independently replaced by an alkyl group or the like, and R²³ and R²⁴ may together form a —CH═CH—, where Hs in the —CH═CH— may be each independently replaced by an alkyl group or the like; L is an arbitrary ligand or is absent; and m is a positive integer, 0, or a negative integer.
