Zero-gap electrolysers lead the race for industrial implementation in the electrosynthesis of carbon-based products from waste CO2. Due to their compact structure, these reactors have lower ohmic losses and attain higher energy efficiencies than the alternatives. However, most research conducted on these electrochemical cells dismisses key product-...

As part of a mitigation and adaptation approach to increasing carbon dioxide atmospheric concentrations, we report superior performance of various metal-nitrogen-doped carbon catalysts, synthesized using an easily up-scalable method, for the electrochemical reduction to carbon monoxide and/or formate at industrially relevant current densities up to...

Bimetallic nanoparticles with tailored size and specific composition have shown promise as stable and selective catalysts for electrochemical reduction of CO2 (CO2R) in batch systems. Yet, limited effort was devoted to understand the effect of ligand coverage and postsynthesis treatments on CO2 reduction, especially under industrially applicable co...

The electrochemical reduction of carbon dioxide (CO2) is a promising technology in light of energy transition and industrial electrification. In this study, two different electrolyzer configurations, flow-through and flow-by modes, were analyzed for the production of carbon monoxide to resolve the CO2 mass transfer limitation problem at high curren...

Over the last few years, the scientific community has paid lots of interest in the electrochemical CO2 reduction (ECR) as a possible solution for earth’s global warming and the transitioning to a CO2 neutral industry. The majority of the researchers focus on improving the catalyst material, leading to higher current densities at lower cell potentia...

Photocatalytic processes, like photo-Fenton (PF), are being successfully employed in the decontamination of diverse wastewaters. However, some drawbacks associated with solar collectors’ cost and efficiency loss over time (due to the soiled of the reflective surface) are blocking their application at industrial scale. In this work, aiming the cost...
