Claim 0:
1. A method of making a transition metal catalyst, the method comprising the steps of:
(a) forming a slurry comprising carbon black particles and an aqueous solution comprising a salt of a transition metal M and an oxygen-containing chelating agent;
(b) mixing the slurry, whereby the aqueous solution is absorbed by the carbon black particles;
(c) separating the carbon black particles containing the absorbed solution from the non-absorbed solution;
(d) drying the separated carbon black particles to obtain a solid product; and
(e) heating the solid product, whereby a first portion of M is oxidized, a second portion of M is reduced to form nanoparticles comprising M0, and a carbon matrix comprising graphene forms and surrounds the nanoparticles to form the catalyst.
