P-M-C complex materials were prepared by polymer template coordination with metal-ion loaded with a carbon-reduction method (P standing for polymer, M for nanometal Fe, Co and Ni particles, and C for carbon XC72). The interim production was characterized by IR to be the target polymer P; then the result of TEM indicated that the majority of the Fe, Co and Ni nanoparticles were between the size of 20 and 30 nm, part of which were at 10 nm, which were dispersed uniformly on polymer P. The existence of Fe, Co and Ni was approved by SEM-EDS. The electrocatalytic activity of the P-M-C electrode was investigated by cyclic voltammetry and chronopotentiography. The results showed that in alkaline medium the catalysts exhibited very high electrocatalytic activity and stability for the electro-oxidation of ethanol. HPLC result indicated that a part of the product after the oxidation of ethanol was a mixture of acetaldehyde and acetic acid.
