摘要： A method for producing A hydrogen gas from formic acid, characterized in that at least one heterogeneous catalyst is used to transform the formic acid into hydrogen gas. The at least one heterogeneous catalyst contains heterogenized ruthenium. According to a first aspect of the invention, the at least one heterogeneous catalyst contains at least one hydrophilic phosphine ligand which is m-TPPTS (meta-trisulfonated triphenylphosphine). The at least one heterogeneous catalyst is preferably obtained by mixing an aqueous solution of RuCl3 with hydrophilic phosphine, firstly activated by carrying out a homogeneous reaction with formic acid and by adding at least one solid structure.
