Iron and Nickel Substituted Perovskite Cobaltites for Sustainable Oxygen Evolving Anodes in Alkaline Environment

ChemSusChem, Volume 18, Issue 6, March 15, 2025.
Perovskite oxide catalysts with reduced Co content, substituted by Fe and Ni, are synthesized and studied for their activity in the oxygen evolution reaction in alkaline media. An increase in the intrinsic catalytic activity (obtained by the (RctCdl)−1 product) of the base material (Ba0.5Gd0.8La0.7Co2O6‐δ) is seen for an as high as 70 % substitution of

Recent advances in boosting interfacial bubble dynamics with external fields

Droplet, EarlyView.
External physical fields, including acoustic, magnetic, thermal, mechanical, and optical stimuli, accelerate the entire bubble‐dynamics sequence of nucleation, growth, and detachment. Abstract The efficiency of industrial electrocatalytic reactions depends not only on generating gaseous products but also on their detachment from the catalyst surface ...

Optimizing Intermediate Adsorption on FeNi3 Alloy by Substrate Defect‐Engineering for Enhanced Oxygen Electrocatalysis

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
The presence of carbon edge defects and graphitic valley nitrogen significantly alters the energy band structure of the catalyst, enhancing the desorption of oxygen‐containing intermediates and thereby improving the performance of the oxygen reduction reaction (ORR), oxygen evolution reaction (OER), and zinc‐air battery (ZAB).

Atmosphere‐Regulated Pyrolysis Switches ORR Pathway on Iron‐Based Catalyst for H2O2 Synthesis and Zn‐Air Batteries

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Two Fe‐based electrocatalysts with different ORR selectivity were synthesized from a FeMOF in N2 or air atmosphere, which show promising prospects in Zn‐air battery and H2O2 production. Developing simple methods to achieve flexible regulation of oxygen reduction reaction (ORR) selectivity is essential for sustainable energy technologies, yet remains ...
