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

EcoEnergy, 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 ...

Electronic Synergy in NiCo‐Embedded Nitrogen‐Doped Hollow Mesoporous Carbon Spheres for Bifunctional Oxygen Catalysis and Zinc–Air Batteries

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This study employs a hard‐templating etching strategy to synthesize N‐doped hollow mesoporous carbon spheres embedded with NiCo nanoparticles (denoted as NiCo@N‐HMCS). The optimized catalyst exhibits exceptional bifunctional catalytic activity for the oxygen reduction reaction (ORR) and oxygen evolution reaction (OER) in alkaline media, achieving a ...

Polycarbazole–NiOOH Interfacial Engineering of BiVO4 Photoanodes for Efficient and Stable Solar Water Splitting

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A π‐conjugated carbazole (p‐CBZ) layer is electro‐polymerized on BiVO4 to form a p–n heterojunction that enhances charge separation and suppresses surface recombination, while a NiOOH co‐catalyst accelerates oxygen evolution kinetics. The synergistic BVO/p‐CBZ/NiOOH photoanode delivers a high photocurrent density and long‐term stability for efficient ...

Morphology Engineering Derived CoOOH With Tunable Oxygen Vacancies for Potential‐Dependent Selective Electrooxidation

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Through a morphology engineering strategy applied to CoFe PBA precursors, we successfully fabricated the CoOOH active phase enriched with oxygen vacancies and abundant edge sites. The introduced oxygen vacancies not only enhance the strong adsorption capacity for oxygen‐containing substrates but also suppress the overoxidation of HMFCA, thus enabling ...

Cu‐Doped Amorphous High‐Entropy Hydroxides Activating Electrochemical Reconstruction: Triggering LOM and Chloride Repellency for Enhanced Water and Seawater Oxidation

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Copper‐doped amorphous high‐entropy hydroxide (CuNiCoFeCrOH) is constructed via one‐step electrodeposition. Cu doping promotes electrochemical reconstruction by accelerating Cr leaching and re‐adsorption, triggering LOM and chloride repellency for efficient water and seawater oxidation.

Enhanced Electron‐Capturing by Single‐Atomic Iron on Pyridinic N‐Deficient Carbon Drives Self‐Oxidative Degradation of Pollutants

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Pyrolysis of FeOx/g‐C3N4 and ZIF‐8 is performed to introduce Fe single atom and pyridinic nitrogen vacancies onto N‐doped carbon. This modification enables the materials to efficiently extract electrons from ciprofloxacin (CIP) and activate dissolved oxygen. 100% of CIP was degraded within 1 min without adding any oxidant.
