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 ...

Advanced Energy Materials, EarlyView.Hydrocarbon membranes have the potential to significantly enhance the efficiency of water electrolyzers. However, their application is often limited by insufficient stability resulting from excessive swelling. This work presents a strategy to achieve efficient, safe and stable operation of a 24 µm thin hydrocarbon membrane by combining a modified ...

Arylhydrazines: Convenient Homogeneous Reductants for Scalable Cross‐Coupling
Angewandte Chemie, EarlyView.Reductive cross‐couplings enable efficient C–C bond formation but are limited by the heterogeneity of Zn or costly reagents like TDAE. We report arylhydrazines as inexpensive, convenient reductants for Ni‐catalyzed sp2–sp3 coupling of aryl halides and secondary alkyl iodides. Mechanistic studies support hydrazine‐mediated NiII reduction for a NiI/NiIII

CO Spillover‐Induced Directed C─C Coupling for CO2 Electroreduction to Multicarbon Products
Advanced Energy Materials, EarlyView.Efficient CO2 electroreduction to C2+ is achieved by engineering Cu@Ag interfaces, which enhance interfacial CO spillover from Ag to Cu, enrich *CO coverage, and accelerate C─C coupling. A quantitative relationship between CO spillover rate and C2+ activity is also established, defining spillover as a measurable descriptor and advancing rational ...

Advanced Energy and Sustainability Research, EarlyView.Considerable improvement in the performance of fully‐hydrocarbon‐based fuel cells is necessary to replace and compete with Per‐ and polyfluoroalkyl substances‐containing fuel cells. Herein, a way to enhance the ionic conductivity of the catalyst layer (CL) by incorporating insoluble ionomer particles into the CL is presented.
