Bottom-up evolution of perovskite clusters into high-activity rhodium nanoparticles toward alkaline hydrogen evolution

Gaoxin Lin et al.

Summary: In this study, we demonstrate a bottom-up evolution route to prepare ultrafine Rh nanoparticles with large lattice spacings and grain boundaries by electrochemically reducing Cs3Rh2I9 halide-perovskite clusters on N-doped carbon. These Rh nanoparticles derived from Cs3Rh2I9 clusters exhibit significantly enhanced mass and area activity toward hydrogen evolution reaction in both alkaline and chloralkali electrolyte, surpassing liquid-reduced Rh nanoparticles and bulk Cs3Rh2I9-derived Rh via top-down electro-reduction transformation. Theoretical calculations reveal that water activation could be promoted on Cs3Rh2I9 clusters-derived Rh nanoparticles enriched with multiply sites, thereby facilitating alkaline hydrogen evolution.

Cu-Doped Heterointerfaced Ru/RuSe2 Nanosheets with Optimized H and H2O Adsorption Boost Hydrogen Evolution Catalysis

Kai Wang et al.

Summary: We report a new design of Cu-doped Ru/RuSe2 heterogeneous nanosheets (NSs) with optimized H and H2O adsorption strength for highly efficient HER catalysis in alkaline media. The Cu-doped Ru/RuSe2 NSs exhibit a small overpotential, low Tafel slope, and high turnover frequency for HER, making them among the best catalysts in noble metal-based electrocatalysts toward HER. This work demonstrates that heterogeneous interface modulation opens up a new strategy for the designing of more efficient electrocatalysts.

A universal chemical-induced tensile strain tuning strategy to boost oxygen-evolving electrocatalysis on perovskite oxides

Daqin Guan et al.

Summary: This study introduces tensile strain into perovskite materials through a facile thermochemical reduction method, improving material performance in the oxygen-evolving reaction. By modulating solid-liquid tension, the hydrophobic perovskite is transformed into a hydrophilic one, enhancing the adsorption of hydroxyl reactants. Surface-sensitive and bulk-sensitive absorption spectra confirm the effectiveness of this strategy in introducing oxygen vacancies and transforming local structures. Theoretical computations reveal reduced energy barriers for hydroxyl adsorption and optimized electron transport.
