Dynamic Phase‐Evolution‐Triggered Strong Metal‐Support Interaction Configures Atomic Ru Sites for Superior Alkaline Hydrogen Evolution

Shuyu Jia, Xi Zhang, 郭跃佳, J H Zhang et autres

ABSTRACT Phase engineering effectively modulates the strong metal‐support interaction (MSI) in heterogeneous catalysts. However, the dynamic manipulation of MSI through in situ phase transition remains underexplored. Herein, an acid‐mediated strategy for in situ 1T→2H phase transformed MoSe 2 has been reported to …

Alleviating OH Blockage: Asymmetric Adsorption Configuration of Co–OH–M (d 10 ) for Seawater Electrolysis

Shen Wang, Jiachen Zhang, Shuyu Jia, Qicheng Liu et autres

Cobalt-based phosphides, sulfides, and selenides (Co-Xides, X = P, S, Se) are promising corrosion-resistant anode catalysts for seawater electrolysis, which stems from the reconstruction of oxyanion layers (PO 4 3–, SO 4 2–, SeO 4 2– ) that electrostatically repel Cl – …
