“…The high-resolution XPS spectrum of N1s can be fitted into four peaks at around 397.7, 399.2, 400.5 and 402.5 eV, which are assigned to pyridinic N, pyrrolic N, graphitic N and oxygenated N, respectively (Figure 2e). 39 As shown in Figure 2f, the N K-edge XANES spectrum of NG changes with the annealing temperature from 200 to 600 o C, indicating the corresponding variation of N species. 40 Specially, the N5 peak at ~406 eV in GPA-200 is ascribed to the S excitation of C-N bonds, while N4 at ~402 eV can be attributed to the attachment of urea species.…”

As the most desirable hydrogen production device, the highly efficient acidic proton exchange membrane water electrolyzers (PEMWE) are severely limited by the sluggish kinetics of oxygen evolution reaction (OER) at the anode. Rutile IrO2 is a commercial acid‐stable OER catalyst with poor activity and high cost, which has motivated the development of alternatives. However, hitherto most of the designed acidic OER catalysts have disadvantages of low activity or stability, which cannot meet the requirement of industrial applications. Thus, exploring suitable strategies to enhance the activity and stability of cost‐effective acidic OER catalysts is crucial for developing the PEMWE technique. In this review, the main OER mechanisms, different types of catalysts, and their activity and stability characteristics are summarized and discussed, and then possible strategies to improve activity and stability are proposed. Finally, the problems and prospects of such catalysts are generalized to shed some light on the future research of advanced catalysts for acidic OER.
