Coupling Electrochemical CO2 Reduction With Ethanol Oxidation for Acetate Production in a Dual‐Electrolyzer System

Angewandte Chemie, EarlyView.
A tandem cell system coupling electrochemical CO2 reduction and electrochemical ethanol oxidation is demonstrated for overall acetate production, providing concepts for a CO2‐negative bioethanol to acetate pathway. ABSTRACT Bioethanol production from biomass is suggested as a strategy for greener fuel production.

Enhancing the Electrocatalytic Oxidation of 5-Hydroxymethylfurfural Through Cascade Structure Tuning for Highly Stable Biomass Upgrading

Nano-Micro Letters
A novel cascade strategy is proposed to construct Pd-NiCo2O4 electrocatalyst. First time discovery that Ni incorporation together with Pd loading is able to balance the competitive adsorption of OH– and 5-hydroxymethylfurfural.
