Hierarchical Porous Carbon Spheres Loaded CoOX (CoOx/HPCS) for Efficient Oxygen Reduction Reaction in Alkaline Media

“…According to the previous researches, methanol can be easily oxidized at the anode, and diffused to the cathode accompanied by proton migration, thus leading to a decrease in the performance of the fuel cell. Besides, some intermediate products like CO groups, such as ‐CO ads , ‐HCHO ads , and ‐HCOOH ads and so on, will be generated during ORR processes on the electrode surface of Pt‐based catalysts, and be adsorbed on catalyst surface, thereby leading to the poisoning of Pt‐based catalysts and the degradation of catalytic activity [52,53] . Therefore, the two crucial factors, those are durability and methanol crossover effect of Pt‐based electrocatalysts, are severely limiting the wide industrial application of fuel cells, especially for the direct methanol fuel cells (DMFCs) [54] .…”

[52,53] Therefore, the two crucial factors, those are durability and methanol crossover effect of Pt-based electrocatalysts, are severely limiting the wide industrial application of fuel cells, especially for the direct methanol fuel cells (DMFCs). [54] It is of great significance to develop non-precious metal catalysts with outstanding resistance to methanol toxicity.…”

Glu-Co-Assisted Iron-Based Metal–Organic Framework-Derived FeCo/N Co-Doped Carbon Material as Efficient Bifunctional Oxygen Electrocatalysts for Zn–Air Batteries

“…The C1s spectrum in Figure 2b can be decomposed into four peaks at 282.95 eV, 283.73 eV, 285.74 eV, and 289.36 eV, representing C=C, C-N, C=O, and π-π*, respectively, and the existence of C-N demonstrates the successful doping of N into the carbon matrix [51]. Figure 2c exhibits the high-resolution spectrum of N1s, in which four peaks are fitted: pyridinic N (396.91 eV), Fe/Co-Nx (397.69 eV), pyrrolic N (399.01 eV), and graphitic N (400.62 eV) [52]. Figure S6 (Supplementary Materials) displays the N1s spectra of the Fe-C and FeCo-CNTs, with the respective N contents detailed in Table S3 (Supplementary Materials).…”

“…Therefore, the development of novel nonprecious metal catalysts with excellent catalytic activity and stability in the ORR has become mainstream. [12][13][14] In recent years, transition metal coordinated nitrogen carbon materials (M-N-C) have been considered potential ORR electrocatalysts to replace Pt-based catalysts owing to their good ORR properties. 15,16 Fe-N-C catalysts have attracted much attention, particularly because of the synthesis method being simple and cost-effective.…”
