WebThe electrochemical reduction of carbon dioxide, also known as electrolysis of carbon dioxide, is the conversion of carbon dioxide ( CO 2) to more reduced chemical species using electrical energy. It is one possible step in the broad scheme of carbon capture and utilization, nevertheless it is deemed to be one of the most promising approaches. [1] WebFigure 14.5 Electrolysis. In an electrolytic cell, electricity is forced through the cell to induce a nonspontaneous redox reaction. Here, the redox reaction 2 H 2 O → 2 H 2 + O 2 is being caused by the introduction of electricity, which is supplied by the battery. Electrolysis has many applications. For example, if NaCl is melted at about ...
