Impact of Crystallinity and Ni-Fe Composition on the Oxygen Evolution Performance of Ni_xFe_1-xO Electrocatalysts in Anion Exchange Membrane Water Electrolysis. [PDF]

ChemSusChem
Expensive platinum group metals (PGMs) are used to enhance the anodic oxygen evolution reaction (OER) kinetics, and they represent a real bottleneck in the commercialization of anion exchange membrane water electrolyzers (AEMWEs). Therefore, we present a scalable and economical homogeneous precipitation method to synthesize NixFe1‐xO nanoparticles with

Sustainable One-Pot Electrochemical Approach for Entrapment of Multi-Enzymes and Biocompatible Redox Mediator. [PDF]

Chempluschem
Novel enzyme‐modified carbon felt electrodes are constructed for efficient bio‐electrocatalysis. Simultaneous electrodeposition of pyrrole and neutral red provides a facile one‐step approach for enzyme immobilization. The biocompatible conductive polymer matrix performs for the entrapment of dehydrogenase enzymes on the electrode and ensures sufficient
