Synergistic Co‐Doping of Barium and Cobalt Enables Stable and Active RuO2 for Acidic Water Oxidation
Angewandte Chemie, EarlyView.Achieving high activity and long‐term durability with non‐iridium catalysts for the acidic oxygen evolution reaction (OER) remains a challenge. This work presents a co‐doping strategy that incorporates Ba and Co into home‐made RuO2, which introduces lattice strain and favorable electronic structure regulation, thereby enhancing both activity and ...

Experimental Observation of a Calcium Silicon Double Carbonate
Angewandte Chemie, EarlyView.High‐pressure and ‐temperature reactions between Ca5(Si2O7)(CO3)2 tilleyite and CO2 carbon dioxide yield the first experimental evidence of the double carbonate Ca2Si(CO3)4 and a new Ca2(C4O10) phase containing tetrahedral [CO4] units. These findings reveal unexpected carbonate chemistry and highlight pathways for carbon incorporation under mantle ...

Advanced Energy and Sustainability Research, EarlyView.This study explores Cs2PtX6 (X = Cl, Br) lead‐free perovskites as sustainable photocatalysts for solar‐driven water splitting. Cs2PtBr6 outperforms Cs2PtCl6 in oxygen evolution due to its narrower bandgap and efficient charge carrier dynamics, enabling enhanced light absorption and charge separation.
