A method for creating a metal-carbon composite. In one embodiment, the method includes the steps of providing a polymer Schiff base transition metal id='REI-00001' date='20221115' filmid='REI-00001' id='REI-00002' date='20221115' complex id='REI-00002' precursor id='REI-00003' date='20221115' film id='REI-00003' having a chemical structure of the formula [M(Schiff)]n and a recurring unit and a transition metal selected from the group consisting of nickel, palladium, platinum, cobalt, copper, iron; Schiff is a tetradentate Schiff base ligand selected from the group consisting of Salen (residue of bis(salicylaldehyde)-ethylenediamine), Saltmen (residue of bis(salicylaldehyde)-tetramethylethylenediamine, Salphen (residue of bis-(salicylaldehyde)-o-phenylenediamine), a substituent in a Schiff base is selected from the group consisting of H—, and carbon-containing substituents, preferably CH3—, C2H5—, CH3O—, C2H5O—, and Y is a bridge in a Schiff base depositing the polymer Schiff base transition metal precursor film onto a support substrate; and heating the polymer Schiff base transition metal id='REI-00004' date='20221115' complex id='REI-00004' precursor film and support substrate in a furnace in an inert atmosphere.
