      Abstract: Formic acid has been proposed as   energy carrier and can be produced from CO2 and water over an   appropriate catalyst. An electrochem. route from CO2 and water is   also possible. The obtained formic acid can be easily stored and   transported. It can be used as a convenient source for H2 through   its decompn. by decarboxylation. In present work decompn. of   formic acid to hydrogen and carbon dioxide was carried out in the   presence of ruthenium chloride. The active catalyst was isolated   from the reaction mixt. NMR, FTIR and single crystal x-ray   diffraction anal. of the isolated catalyst revealed the in situ   formation of a tetraruthenium dodecacarbonyl tetrahydride   ([Ru4(CO)12H4]) from RuCl3 under reductive conditions.
