Revealing the Inhibitory Effect of Strong Metal Support Interactions on CO2 Poisoning in Urea Oxidation Reaction

open access: yesEcoEnergy, EarlyView.
The strong metal‐support interaction between sodium tungsten bronze and NiCo alloy reduces carbon dioxide adsorption, thereby mitigating catalyst poisoning and enabling a highly efficient and stable urea oxidation reaction. ABSTRACT The development of highly active urea oxidation reaction (UOR) catalysts with superior anti‐poisoning capability poses a ...

A Review of Grain Boundaries: Formation Mechanism, Synthesis Strategy, and Application in Electrocatalysis

open access: yesEcoEnergy, EarlyView.
An overview of grain boundary engineering in the field of electrocatalysis. ABSTRACT Key electrocatalytic reactions such as HER, OER, ORR, CO2RR, and NRR offer promising routes for storing renewable energy as chemical fuels. However, their widespread application is constrained due to the lack of highly active and stable catalysts. Grain boundaries (GBs)

RuO2‐Based High‐Entropy Oxide and Its Asymmetric Catalysis on Polysulfide Conversion in Lithium–Sulfur Batteries

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
RuO2‐based high‐entropy metal oxide shows an asymmetric catalysis on polysulfide conversion with an inferior kinetics enhancement of polysulfide generation, but a superior promotion of Li2S deposition, which greatly favors the inhibition of shuttle effect and the improvement of battery performance. High‐entropy oxides with five or more metal components
