Multiple Functional Engineering Strategies and Active Site Identification in Ru‐Based Electrocatalysts for Catalytic Conversion Reactions

Advanced Materials, Journal Year: 2025, Volume and Issue: unknown

Published: April 3, 2025

Electrochemical conversion has been regarded as an ideal technology for achieving clean and sustainable energy, showing significant promise in addressing the increasingly serious energy crisis environmental pollution. Ru-containing electrocatalysts (RUCE) outperform other precious metals due to elevated intrinsic activity superior cost-effectiveness, developing into a promising candidate electrochemical reactions. A challenge field of catalyst discovery lies its heavy reliance on empirical methods, rather than approaches that are rooted rational design principles. This review first concentrates catalytically active sites critical factors governing catalytic performance durability. Then, comprehensive summary multifunctional modification strategies ranging from nanoscale atomic scale is explored control structure improve performance. By unveiling roles each component modified RUCE at level, their identified discussed establish structure-performance relationship catalysts. Finally, challenges perspectives Ru-based materials hydrogen, oxygen, nitrogen reactions presented inspire further efforts toward understanding meet ever-growing demand future.

Lead Derivative‐Based Precursor Engineering Enables Halogen‐Uniform Perovskite Solar Cells with Enhanced Stability and Mechanical Tolerance

Advanced Materials, Journal Year: 2025, Volume and Issue: unknown

Published: April 24, 2025

Abstract Perovskite solar cells (PSCs) with supreme opto‐electrical properties and solution‐processability have attracted tremendous interest. To realize state‐of‐the‐art efficiencies in PSCs, delicate control of bandgap ( E g ) is required, which generally involves using mixed halogens. This, however, can result unfavorable phase segregation to negatively influence on the target efficiency long‐term stability. Herein, a viable precursor method demonstrated for preparing halide‐uniform perovskites based lead derivatives nPbI 2 :1PbXA. It found that :1PbXA enables tuning bonding preference strength between PbI PbBr precursor, leading generating stable ‐I‐Br‐I‐Br‐ fragments, eventually minimizes halide perovskite. The approach been applied series wide‐bandgap perovskites, achieving boosted 21.3% 20.3% CsPbI 2.8 Br 0.2 (bandgap 1.74 eV) Cs FA 0.8 I 1.9 1.1 1.77 cells. Interestingly, connection modified homogeneity mechanical tolerance found: better uniformity distribution, higher resistance perovskite compressive or bending forces. halogen exhibit impressive stability, retention >90% initial after 1500 h continuous illumination under maximum power point tracking.
