Rare earth-based nanomaterials hold great promise for applications in the electrocatalysis field owing to their unique 4f electronic structure, adjustable coordination modes, and high oxophilicity. As a cocatalyst, location of rare earth elements can alter intrinsic properties support, including environments, structure evolution under applied potentials variable manner, potentially impact catalytic performance with respect activity, stability, selectivity. Therefore, comprehensive understanding effects elements' on local reaction mechanisms is prerequisite designing advanced nanomaterials. In this review, have been categorized into three main groups based upon namely lattice, surface, interface structure. We initially discuss recent advances representing breakthroughs realize controllable synthesis Next, we state-of-the-art modulation strategy employed enhance performance. Combined characterizations, role process also discussed. Finally, further highlight future research directions remaining challenges development practical applications.

Abstract Accurately regulating the reactive sites of catalysts is vital for highly efficient catalytic processes but still faces considerable challenges. In view this, a local oxidation‐state asymmetric Mn‐O‐Ru bridged moiety developed by introducing Mn atoms into RuO 2 host. The synergistic effect respective active on microstructure ensures its excellent alkaline HER performance. Theoretical calculations profiled that induced moiety, water dissociation ability Ru significantly boosted, while bridging oxygen exhibits optimal hydrogen adsorption free energy. As predicted, Mn‐RuO catalyst achieved overpotentials as low 118 and 160 mV at industrial level current densities 1 A cm ‒2 in m KOH, respectively, superior to commercial Pt/C catalyst. Such electrocatalyst can operate stably with long lifetime 300 h 10 mA under conditions. Furthermore, it only requires 1.87 V reach density 1.0 when serving cathode an assembled flow cell. This work provides new insight environment design obtaining ideal electrocatalysts.
