Copper-based nanostructured catalysts for efficient and selective CO2 electroreduction – synthesis, catalytic performance, and mechanistic analysis
In the past decades, the atmospheric CO2 emissions increased with the unrestrained combustion of fossil fuels to meet the growing energy demand, leading to serious environmental pollution and climate issues. The electrochemical CO2 reduction reaction (CO2RR) is a promising alternative to convert …

Technoeconomic and mechanistic insights into the electroreduction of carbon dioxide to value added chemicals
… a rapid rise in the atmospheric carbon dioxide (CO2) levels, especially in the past few decades, with the daily average value crossing and staying above the 400 ppm mark in 2016 for the first time in recorded human history. These increased CO2 levels (along with other greenhouse gases) have been …

Electrocatalytic CO2 Reduction by Self-Assembled Monolayers of Metal Porphyrins
… issue hindering the successful utilization of CO2 electroreduction processes in industry is the lack of selective, durable, and efficient catalysts. We design a new heterogenous molecular architecture for CO2 electrocatalysts by attaching alkyne-terminated metal (Fe, Co) porphyrins via click …
