Abstract Metal/nitrogen‐doped carbons (M−N−C) are promising candidates as oxygen electrocatalysts due to their low cost, tunable catalytic activity and selectivity, well‐dispersed morphologies. To improve the electrocatalytic performance of such systems, it is critical gain a detailed understanding structure properties through advanced characterization. In situ X‐ray absorption spectroscopy (XAS) serves powerful tool probe both active sites structural evolution materials under reaction conditions. this review, we firstly provide an overview fundamental concepts XAS then comprehensively review setup application in XAS, introducing electrochemical cells, experimental methods, well primary functions on applications. The M−N−C catalysts caused by interplay with electric fields, electrolytes reactants/intermediates during reduction subsequently discussed detail. Finally, major challenges future opportunities exciting field highlighted.

The oxygen reduction reaction (ORR) is a key process in green energy conversion technology. Heteroatom doping has been proven to be prospective strategy prepare metal-free carbon-based electrocatalysts, but such methods often suffer from uncontrollable catalyst frameworks and imprecise active sites. Herein, an organic heterocyclic adopted modulate the charge redistribution of alkynyl-containing conjugated microporous polymers (CMPs) by introducing varied five-membered structures. Among these CMPs, S, 2N-containing thiadiazole molecule (CMP-Tdz) with carbonized alginate materials (CCA ) displays remarkable quasi-four-electron-transfer ORR pathway, exhibiting excellent half-wave potential (E1/2 0.77 V, coupled superior methanol tolerance electrochemical stability, which are among highest performance catalytic material systems. Density functional theory calculations prove that high catalysts originates sp-hybridized C atom (site-2) activated their adjacent Importantly, structures can also local distribution, increase dipole moment, significantly improved kinetics. This incorporation chemically designed heterocyclic-containing alkynyl-CMPs provides new approach developing efficient electrocatalysts for fuel cells.
