TL;DR: This article summarized the recent progress in understanding OER mechanisms, which include the conventional adsorbate evolution mechanism (AEM) and lattice-oxygen-mediated mechanism (LOM) from both theoretical and experimental aspects, and introduced strategies to reduce overpotential.

TL;DR: The specific and mass activity activities of some state-of-the-art catalysts are benchmarked to facilitate the comparison of catalyst activity for these four reactions across different laboratories.

TL;DR: A general principle is concluded that the occupancy of the active cation in the octahedral site is the activity descriptor for the ORR/OER of spinels, consolidating the role of electron orbital filling in metal oxide catalysis.

TL;DR: This tutorial review aims to summarize and analyze the approaches for measuring the surface areas of metal oxide electrocatalyst for evaluating and comparing their intrinsic electrocatalytic activities, and provides some general guidelines for experimentally measuring the electrochemically active surface area (ECSA).

TL;DR: An overview of the current developments in alkaline HER catalysts is provided, as well as the design principles for the future development of heterostructured nano- or micro-sized electrocatalysts are provided.
