This work developed a non-precious carbon-cladding catalyst with excellent SO2 electrooxidation performance, which was synthesized through pyrolyzing a BP2000 supported composite precursor of melamine and Pluronic F127 dispersed FeCl3. This Fe-N-doped catalyst displays the onset and half-wave SO2 oxidation potential of 0.516 V and 0.629 V, respectively, which are particularly close to those of the Pt/C (JM, 20%). This carbon-cladding catalyst exhibits the higher SO2 catalytic activity than Pt/ C, when the applied oxidation potential is above 1.194 V. Furthermore, stability of this catalyst is also better than Pt/ C after the accelerated durability tests in H2SO4. Based on physical characterizations, the effectively doped Fe-N, well embedded Fe3C substances as well as the high surface area, large pore volume and mesoporous structures in the catalyst are synergetic responsible for its excellent SO2 electrooxidation performance and better stability.
