Balancing Electrons to Break the Activity‐Selectivity Trade‐Off in H2O2 Electrosynthesis

Advanced Functional Materials, EarlyView.
Carrier‐concentration balancing in CuS is achieved by coupling cobalt dopants with cobalt vacancies, converting CuS from p‐ to n‐type to accelerate 2e− ORR while withdrawing excess carriers to optimize *OOH binding for H2O2 desorption. The catalyst reaches 8.14 mol g−1 h−1 with >84% selectivity in 1.0 M KOH and drives robust electro‐Fenton dye ...

Understanding the Role of Varying Ti3C2Tx MXene in Ni/Ti3C2Tx for the Oxygen Evolution Reaction

ChemElectroChem
The current state‐of‐the‐art catalysts for the oxygen evolution reaction (OER) in an anion exchange membrane (AEM) electrolyser are not efficient enough to surpass green H2 produced by other electrolyser technologies, such as Proton Exchange Membrane ...

Nanobiosensor Based on Catalytic Palladium Nanoclusters and Oxidases for Bianalyte Electrochemical Determination: Glucose and Ethanol in Sweat

Advanced Healthcare Materials, EarlyView.
A nanobiosensor for fast and simultaneous determination of sweat glucose and ethanol is presented. Deposited oxidase enzymes consume oxygen in the presence of the substrates, and co‐deposited palladium nanoclusters catalyze the electrochemical oxygen reduction, basis of the detection.

Transition metal/carbon hybrids for oxygen electrocatalysis in rechargeable zinc‐air batteries

EcoMat, 2021
Zinc‐air batteries (ZABs) could be an ideal candidate for challenging energy conversion and storage technology. Usually, the crucial oxygen reduction reaction and oxygen evolution reaction are naturally lethargic and require efficient catalysts to ...

Beyond Presumptions: Toward Mechanistic Clarity in Metal‐Free Carbon Catalysts for Electrochemical H2O2 Production via Data Science

Advanced Materials, EarlyView.
Metal‐free carbon catalysts enable the sustainable synthesis of hydrogen peroxide via two‐electron oxygen reduction; however, active site complexity continues to hinder reliable interpretation. This review critiques correlation‐based approaches and highlights the importance of orthogonal experimental designs, standardized catalyst passports ...

Rapid Water Reduction to H_2 Catalyzed by a Cobalt Bis(iminopyridine) Complex [PDF]

, 2011
A cobalt bis(iminopyridine) complex is a highly active electrocatalyst for water reduction, with an estimated apparent second order rate constant k_(app) ≤ 10^7 M^(–1)s^(–1) over a range of buffer/salt concentrations.

POM‐Based Water Splitting Catalyst Under Acid Conditions Driven by Its Assembly on Carbon Nanotubes

Advanced Materials, EarlyView.
A newly‐engineered POM‐based electrocatalyst incorporating non‐innocent counter cations exhibits fast kinetics for either the OER or HER under strongly acidic conditions (1 m H2SO4), depending on whether it is assembled on carbon nanotubes (1@CNT) or physically mixed with them (1/CNT). In water‐splitting tests using a two‐electrode setup, these systems
