Unveiling Ag-Modulated Cu Active Sites for Enhanced Multicarbon Product Formation in CO Electroreduction.

The development of innovative electrocatalysts for CO reduction reaction (CORR) is essential for producing high-value chemicals and fuels. Here, we report a simple surfactant- and solvent-free strategy to fabricate Cu-Ag bimetallic gas diffusion electrodes (GDEs) via sputtering of Cu onto a carbon substrate, followed by galvanic replacement with Ag. This method yields highly pure and tunable electrodes with minimal processing steps.

Unveiling the Origin of pH-Dependent Catalytic Performance of BiO Nanostructure for Electrochemical CO Reduction.

Over the past decade, the electrochemical conversion of CO into valuable chemicals and fuels has garnered increasing interest as a promising pathway toward a carbon-neutral circular economy. This study investigates BiO gas diffusion electrodes (Bi-GDEs) for the conversion of CO to formic acid/formate (HCOOH/HCOO), which demonstrate excellent selectivity at high current densities. The catalyst is synthesized through a one-pot microwave-assisted process that is rapid, energy-efficient, and scalable, utilizing the green solvent ethylene glycol.

Effects of Annealing Conditions on the Catalytic Performance of Anodized Tin Oxide for Electrochemical Carbon Dioxide Reduction.

The electrochemical reduction of CO (CORR) to value-added products has garnered significant interest as a sustainable solution to mitigate CO emissions and harness renewable energy sources. Among CORR products, formic acid/formate (HCOOH/HCOO) is particularly attractive due to its industrial relevance, high energy density, and potential candidate as a liquid hydrogen carrier. This study investigates the influence of the initial oxidation state of tin on CORR performance using nanostructured SnO catalysts.

The electrocatalytic reduction of CO into useful fuels, exploiting rationally designed, inexpensive, active, and selective catalysts, produced through easy, quick, and scalable routes, represents a promising approach to face today's climate challenges and energy crisis. This work presents a facile strategy for the preparation of doped SnO as an efficient electrocatalyst for the CO reduction reaction to formic acid and carbon monoxide. Zn or Ti doping was introduced into a mesoporous SnO matrix via wet impregnation and atomic layer deposition.
