Arene Incorporation and Ring Expansion in the Thermal Decomposition of a Divanadium(III) Complex With Four Bridging Methyl Groups

open access: yesChemistry – A European Journal, EarlyView.
Thermolysis of [{VCp*(µ‐CH3)2}2] (Cp* = η5‐C5Me5) in hexane leads to a tetranuclear cube‐type methylidene complex [{VCp*(µ3‐CH2)}4], while in benzenic solvents C6H5R produces the formal insertion of a CH fragment into the six‐membered aromatic ring of a solvent molecule to give trovacene derivatives with η7‐cycloheptatrienyl ligands [VCp*(η7‐C7H6R ...

Mixed‐Impurity Co‐Poisoning of NH3‐SCR Catalysts: Poisoning Mechanisms, Antagonistic Effects, and Anti‐Inactivation Strategies

open access: yesEcoEnergy, EarlyView.
This review summarizes the synergistic effects of mixed impurities on ammonia‐selective catalytic reduction (NH3‐SCR) catalysts, including the poisoning mechanism of the catalyst caused by mixed impurities, the antagonistic effects between the impurities, and the research on the anti‐poisoning strategies for the catalyst in recent years.

Mitigating Structural Degradation in Hydrated V2O5 for Proton Batteries through Nanoconfinement with a Holey Graphene Matrix

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
HrGO‐supported and confined water‐assisted synergy for faster proton transport in the V2O5 resulted in ultra‐long life over 10 000 cycles at high current density of 1 A g−1. A reaction kinetics study of the ultra‐long cyclability via first principle DFT calculation is also presented. Proton‐based electrochemistry offers a promising solution to the cost

Defect Engineering and Effect of Vacancy Concentration on the Electrochemical Performance of V‐Based MXenes

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Using a top‐down defect engineering approach, controllable vacancy concentrations are introduced into V‐based MXenes by rationally designing the precursor MAX phase, aiming to investigate the effect of vacancy concentration on the electrochemical performance.
