TL;DR: In this article, a series of operando measurements, including in situ X-ray absorption spectroscopy, liquid phase transmission electron microscopy, and in situ Raman spectrograms, were conducted to unravel in real time the structural and chemical stability of P-substituted CoSe2 electrocatalysts under both hydrogen and oxygen evolution reactions (HER and OER) in an alkaline electrolyte.

TL;DR: This work reveals the first empirical demonstration by deploying comprehensive in situ techniques to track the dynamic structural reconstruction/transformation in a model bimetallic system, which establishes a good understanding of the correlation between catalyst surface structure and catalytic selectivity and provides deep insights into designing more developed electrocatalysts for CO2RR and beyond.

TL;DR: In this article, the relationship between material properties and catalytic activity was investigated. And the authors proposed that Fe3+Oh ions mainly confine cobalt ions to the tetrahedral site to restrain the multipath transfer of cobalt ion during the dynamic structural transformation between spinel and oxyhydroxide, continuously activating the catalytic behavior of Co2+(Td) ions.

TL;DR: In this article, in situ techniques that can be used to investigate the structural transformation of catalysts during the reaction have attracted considerable research interest and recent developments in heterogeneous catalysts for OER, HER, and CO2 reduction reaction have been comprehensively summarized.

TL;DR: A two-step process was developed to synthesize Ag nanowires coated with various thicknesses of a CuOx layer for the CO2RR to reveal the existence of reoxidation behavior under cathodic potential and indicate that the reoxidized rate is independent of surface morphology and strongly proportional to the electrochemically surface area.
