Web1 Introduction. As climate change concerns increase, serious efforts are required to mitigate the harmful emission of carbon dioxide (CO 2). [] One of the most promising approaches is converting CO 2 to value-added materials through an electrochemical CO 2 reduction reaction (CO 2 RR) using renewable electricity. [2, 3] Despite the potential of CO 2 RR … WebFor the process, CO 2 (s)→CO 2 (g): Option 1) Both and are positive Option 2) is negative and is positive Option 3) is positive and is negative Option 4) Both and are negative
