“…Nitrogen is mainly presented four bonding configurations within the carbon lattice for N‐doped carbon‐based materials: pyridinic‐N, pyrrolic‐N, graphitic‐N and oxidized‐N ,,,. The corresponding binding energies are about 398 eV, 400 eV, 401 eV and 403 eV, respectively, which is revealed by the X‐ray photoelectron spectroscopy (XPS) spectrum for N 1s ,. The research results usually show that pyridinic‐N and graphitic‐N play a more important role for improving ORR activity, while pyrrolic‐N and oxidized‐N are controversial, which may need to be further researched ,,,,.…”

“…For instance, Guo et al . obtained hierarchically porous 3D‐network nanocarbons electrocatalysts from the biowaste, such as fish scale (FS) by carbonization, ball milling, heat treatment, and acid leaching, as shown in Figure . These porous nanocarbon electrocatalysts exhibit an outstanding ORR electrocatalytic activity with a 0.86 V ORR onset potential in the acidic electrolyte and no decline of half‐wave potential after 6000 cyclic voltammetry (CV) cycles due to the increasing of graphitic‐N content, high BET surface area, and inner porous structure.…”

Recent Advances on Non‐precious Metal Porous Carbon‐based Electrocatalysts for Oxygen Reduction Reaction

Oxygen reduction reaction (ORR) is a crucial process for several significant energy conversion and storage devices, such as metal-air batteries and fuel cells. However, the sluggish kinetics caused by huge activation energy barriers limit the performance. Platinum (Pt) and Pt-based catalysts are still the most efficient catalysts for ORR. Unfortunately, the scarcity, high cost, poor stability, crossover effect and CO poisoning of Pt and Ptbased materials restrict their further development. Carbonbased nanomaterials, especially the non-precious metal porous carbon-based materials (NPC) have been considered as the most promising replacement for Pt and attract the extensive attention of scientists since its high specific surface area and easy regulation can significantly increase the active sites and mass transfer of electrocatalyst. On the other way, the NPC can also be the support of the single metal atoms which can act as the highly efficient ORR electrocatalysts. This review focuses on the recent progress on the applications of NPC at ORR electrocatalyst field.

“…Later, Wang et al produced N‐doped carbon from pig bones and reported that the porosity, N‐doping, and ORR activity were improved with Fe doping. Potential transformation of livestock waste, such as sheep and chicken bones, fish skeletons, and fish scales, were reported to yield catalytically active N‐doped carbon catalysts for the reduction of oxygen.…”

Advanced Biomass‐Derived Electrocatalysts for the Oxygen Reduction Reaction

Recent progress in advanced nanostructures synthesized from biomass resources for the oxygen reduction reaction (ORR) is reviewed. The ORR plays a significant role in the performance of numerous energy-conversion devices, including low-temperature hydrogen and alcohol fuel cells, microbial fuel cells, as well as metal-air batteries. The viability of such fuel cells is strongly related to the cost of the electrodes, especially the cathodic ORR electrocatalyst. Hence, inexpensive and abundant plant and animal biomass have become attractive options to obtain electrocatalysts upon conversion into active carbon. Bioresource selection and processing criteria are discussed in light of their influence on the physicochemical properties of the ORR nanostructures. The resulting electrocatalytic activity and durability are introduced and compared to those from conventional Pt/C-based electrocatalysts. These ORR catalysts are also active for oxygen or hydrogen evolution reactions.

“…The kinetics of a proton-exchange membrane fuel cell is usually limited by the oxygen reductionr eaction (ORR)a tt he cathode, and could be improved by using highly efficient electrocatalysts and highsurface-area catalyst supports with hierarchically porouss tructures. [6][7][8][9][10][11][12][13][14][15] Likewise, an improvement in supercapacitorp erformance also requires hierarchically porous carbon (HPC) electrodes with large specific surfacea reas for accumulating numerous charges. [16][17][18][19][20][21][22][23][24][25][26] The hierarchical pores indicate the coexistence of micro-(with widths smaller than 2nm), meso-( with widths between 2a nd 50 nm), and macropores( with widths larger than 50 nm) in the porousm atrix, in which micropores are able to dramatically increaset he specific surfacea rea and expose many hidden reactions ites to the surface and meso-/ macropores can provide rapid mass-transport pathways and buffering reservoirs for electrolyte ions and/orr eactants.…”

Hierarchically porousc arbon (HPC)d erived from fallen flowers was prepared by ag reen method of combining solvent-freeb all milling with the safe activating agent potassium bicarbonate. By regulating the mass ratio of KHCO 3 to biochar,t he as-prepared HPC materials possess high specific surface areas of up to 2147.9 m 2 g À1 and abundant hierarchical pores comprised of micro-, meso-, and macropores.T he specific capacitanceso ft he HPC materials are able to reach3 02.7 Fg À1 at ac urrent density of 0.5 Ag À1 in 6 m KOH, and the symmetric supercapacitorc omposed of two identicalH PC electrodes shows good stability because 100 %o ft he specific capacitance is retained after 5000 charge/dischargec ycles and 90.5 %o ft he specific capacitance remainsa fter 12 000 cycles.N itrogen self-doped HPC materials also show higher electrocatalytic activity and stronger methanolt olerance for the oxygen reductionr eaction than that of the commercialP t/C catalyst. This preparation method can be extended to the green conversion of other varieties of biomass waste into usefulc arbon materials.
