CATALYST FOR DECOMPOSITION OF FORMIC ACID, METHOD FOR DECOMPOSITION OF FORMIC ACID, PROCESS FOR PRODUCTION OF HYDROGEN, APPARATUS FOR PRODUCTION OR DECOMPOSITION OF FORMIC ACID, AND METHOD FOR STORAGE OR GENERATION OF HYDROGEN

摘要

A catalyst for the decomposition of formic acid, comprising a polynuclear metal complex represented by the formula (1), a tautomer or stereoisomer thereof, or a salt of the complex, the tautomer or the stereoisomer. Wherein M1 and M2 independently represent a transition metal and may be the same as or different from each other; Ar represents a ligand having an aromatic property which may have a substituent, provided that, when the ligand has a substituent, one or more substituents may be present; R1 to R27 independently represent a hydrogen atom, an alkyl group or the like, or R15 and R16 may together form a group: -CH=CH- wherein H's may be independently substituted by an alkyl group or the like, and R23 and R24 may together form a group: -CH=CH- wherein H's may be independently substituted by an alkyl group or the like; L represents an arbitrary ligand or may be absent; and m represents a positive integer, 0 or a negative integer.
