This DECRA aims to realise the direct electrochemical conversion of waste resources using renewable energy to generate urea at ambient conditions. By designing impurity-tolerant single atom catalysts and unearthing their structure-activity relationships, the utilisation of flue gas and wastewater will be materialised. This will advance our understanding in the field as current energy conversion reactions require pure feedstocks.
