摘要： The invention relates to a catalyst according to the formula IrCl(cod)(NHC)]+nP (n=2, 3 or 4), or [Ir(cod)(NHC)(P)]+nP (n=1, 2 or 3), which is suitable to decompose formates in an aqueous reaction system, and for the production of hydrogen gas free of COx or hydrogenation of hydrogen carbonates, wherein Ir means iridium; Cl means chloro; cod means 1,5-cyclooctadiene; NHC means N-heterocyclic carbene, preferably 1-R-3-methylimidasolium chloride, wherein R means C1 to C5 alkyl and P means 1,3,5-triaza-7-phosphaadamantane (pta), monosulphonated triphenilphosphine (mtppms), trisulphonated triphenylphosphine (mtppts), or tetrasulphonated diphenylphosphynopropane (dpppts). Furthermore, the invention relates to a process for the preparation of the catalyst according to the invention. Further, the invention relates to a process for the decomposition of formate in aqueous reaction system, and for the production of hydrogen gas free of COx, still further, a process for the hydrogenation of hydrogen carbonate in an aqueous reaction system, as well as the production of the respective formate. Further, the invention relates to a process for the decomposition of formate according to the invention, and the hydrogenation of the hydrogen carbonate generated in the same reaction system. The invention relates to a hydrogen storage system based on the process according to the invention, preferably accumulator or fuel cell, and the use thereof.
