Formation of a 14‐Electron Intermediate in Iridium Catalysis through Reductive Elimination: Dissociation Is Rate Determining

ChemistryEurope, EarlyView.
Dynamic NMR and trapping studies reveal that POCOP–Ir phenyl hydride complexes perform reductive coupling rapidly but dissociate benzene slowly. PCP–Ir analogs show comparatively slow reductive coupling and faster dissociation. This work experimentally clarifies aspects of C–H reductive elimination in iridium pincer complexes.(POCOP = bisphosphinite ...

A “Two‐Pronged” Strategy Boosting the Activity and Stability of Nickel–Iron Catalysts Toward Anion Exchange Membrane Water Electrolysis

Carbon Energy, EarlyView.
A “two‐pronged” strategy has been developed to construct a substrate‐strengthened, organophosphorus‐protected nickel‐iron electrode for efficient and robust OER electrocatalysis. Owing to the reinforced catalyst–substrate interaction and minimized active site loss by organophosphorus protection, the integrated electrode serves as an robust and ...

Hydroxyl Self‐Trapping Strategy Enables Electrocatalysis at Ampere‐Level Current Densities: Kinetics‐Driven Lattice Oxygen Activation for Cl−‐Rich Alkaline Water Electrooxidation

Carbon Energy, EarlyView.
This study designs a CrOx‐engineered Ni‐based catalyst enabling efficient and stable seawater electrolysis. The catalyst utilizes a dynamic interfacial barrier that selectively adsorbs OH− to repel Cl− corrosion while activating lattice oxygen‐mediated pathways.

Enhancing the d–Electrocatalytic Activity of MXene Through Defect Engineering

Carbon Energy, EarlyView.
Applications of MXene. ABSTRACT Due to their versatile and tunable surface and bulk chemistry, MXenes have great potential as electrocatalysts for batteries and supercapacitors. When compared with other electrocatalytic processes, in electrocatalytic reactions, MXenes could improve ion diffusion and charge transfer by either providing functional groups
