A graphene oxide aerogel (GOA) was formed inside a melamine sponge (MS) framework. After reduction with hydrazine at 60 °C, the electrical conductive nitrogen-enriched rGOA-MS composite material with a specific density of 20.1 mg/cm3 was used to fabricate an electrode, which proved to be a promising electrocatalyst for the oxygen reduction reaction. The rGOA-MS composite material was characterized by elemental analysis, scanning electron microscopy, X-ray photoelectron spectroscopy, and Raman spectroscopy. It was found that nitrogen in the material is presented by different types with the maximum concentration of pyrrole-like nitrogen. By using Raman scattering it was established that the rGOA component of the material is graphene-like carbon with an average size of the sp2-domains of 5.7 nm. This explains a quite high conductivity of the composite obtained.

“…Therefore, it is highly desirable and still challenging to develop non-precious metal ORR catalysts with comparable catalytic performance and higher stability. Over recent years, a series of non-precious metal catalysts (NPMCs) have been exploited for ORR [13][14][15][16], including metal-free nitrogen-doped carbon materials [17][18][19], nanocarbon/transition-metal compound hybrids [20][21][22] and metal oxides [23][24][25]. Among metal oxides, cobalt trioxide (Co 3 O 4 ) shows good ORR performance but low electrical conductivity.…”

Zinc-air battery is one of the most promising next-generation energy conversion and storage systems. Green and low-cost catalysts with high oxygen reduction reaction (ORR) catalytic activity are desired to meet the requirements of Zinc-air batteries. Herein, poly-active centric Co 3 O 4-CeO 2 / CoN -C (ketjenblack carbon) catalysts were prepared by a facile method. The Co 3 O 4 and CeO 2 nanoparticles are uniformly anchored on the surface of Co and N doped carbon support. The half-wave potential of Co 3 O 4-CeO 2 /Co-N-C in the rotating disk electrode testing is close to that of Pt/C. The Zn-air battery using Co 3 O 4-CeO 2 /Co-N-C as the cathode catalyst can provide a high specific capacity of 728 mA h g −1 at 20 mA cm −2 and maintain a stable discharge voltage. The remarkable catalytic performance is mainly attributed to the synergistic effect among Co 3 O 4 , CeO 2 and CoN -C, the outstanding electrical conductivity and the large surface area. Benefitting from the high catalytic activity, environmental friendliness and the facile synthesis process, Co 3 O 4-CeO 2 /Co-N-C catalyst lends itself well to a great prospect in the application of metalair batteries.
