Carbon-based single metal atom or bimetallic, trimetallic, or multimetallic alloy transition metal-containing catalysts derived from exoelectrogen bacteria and their methods of making and using thereof are described. The method comprising the steps of: (a) preparing a solution medium comprising at least an electron donor and an electron acceptor comprised of one or more salts of a transition metal; (b) providing exoelectrogen bacterial cells and mixing the exoelectrogen bacterial cells into the solution medium of step (a); (c) incubating the solution medium of step (b); (d) isolating the exoelectrogen bacterial cells from the incubated solution medium of step (c); and (e) pyrolyzing the exoelectrogen bacterial cells resulting in formation of the catalyst. The electron donor can be formate, acetate, or hydrogen.
