Chemically and electrochemically catalysed conversion of CO2 to CO with follow-up utilization to value-added chemicals

Dennis U Nielsen, Xin-Ming Hu, Kim Daasbjerg, Troels Skrydstrup https://doi.org/10.1038/s41929-018-0051-3 Carbon dioxide is ubiquitous and a vital molecule for maintaining life on our planet. However, the ever-increasing emission of anthropogenic CO2 into our atmosphere has provoked dramatic climate changes. In principle, CO2 could represent an important one-carbon building block for the chemical industry, yet its high thermodynamic…
