Scalable Synthesis of Multi-Metal Electrocatalyst Powders and Electrodes and their Application for Oxygen Evolution and Water Splitting

Ieva A. Cechanaviciute et al.

Summary: Multi-metal electrocatalysts offer a wide range of catalytic possibilities through synergistic element interactions. This study presents a polymer/metal precursor spraying technique that enables the production of diverse multi-metal catalyst materials. The synthesized catalysts, including CoNiFeMoCr, were characterized and tested for the oxygen evolution reaction (OER). The CoNiFeMoCr catalyst exhibited a polycrystalline structure, and operando Raman measurements indicated the involvement of multiple active sites. Additionally, CoNiFeMoCr electrodes supported by Ni foam were utilized for water splitting in flow-through electrolysis cells and alkaline membrane electrode assembly (MEA) configurations, showing promising performance with high current densities.

From waste to value-Glycerol electrooxidation for energy conversion and chemical production

Michael Braun et al.

Summary: The defossilization of the chemical industry, which aims to reduce CO2 emissions, is hindered by the carbon-based nature of many chemical products today. To address this challenge, technologies like electrochemical glycerol oxidation reaction (GOR) can convert waste glycerol from biodiesel production into value-added products. Scaling up such systems to industrial scale requires considering market parameters and selectivities of electrocatalysts. This study aims to explore research opportunities for GOR in the transition from fossil to renewable energy resources, particularly in synthesizing GOR products on an industrial scale.

Effect of Electrolyte Composition and Concentration on Pulsed Potential Electrochemical CO2 Reduction

Rileigh Casebolt et al.

Summary: The relationship between electrolyte concentration/composition and product distribution for pulsed potential electrochemical CO2 reduction (eCO(2)R) differs from that of constant potential eCO(2)R. Pulsed potential eCO(2)R suppresses H-2 formation relative to CH4 due to periodic desorption of surface protons, while constant potential eCO(2)R favors H-2 production. Increasing KCl concentration during pulsed potential eCO(2)R greatly enhances C-2 product formation.
