Description

Technical Field

[0002] Global warming has made carbon dioxide the most concerned greenhouse gas, and carbon dioxide emission reduction, capture and utilization technologies have also become the most concerned high-tech today.

[0003] The existing technology has the following problems: the electrocatalytic conversion of carbon dioxide is an important technology for the utilization of carbon dioxide. Its principle is roughly as follows: water undergoes an oxidation reaction at the anode to generate hydrogen ions and oxygen. The hydrogen ions migrate to the cathode through a mass transfer process and participate in the electrocatalytic reduction reaction of carbon dioxide at the cathode to generate formic acid and side reaction products. The anode and cathode here refer to the plates connected to the positive and negative electrodes of an external power supply, respectively. The positive electrode plate generates hydrogen ions and oxygen, and the negative electrode plate participates in the electrocatalytic reduction reaction of carbon dioxide. The existing positive and negative electrodes are mostly directly arranged in the carbon dioxide catalytic conversion reactor, lacking the necessary reasonable design, which leads to inconvenience in the installation and removal of the plates on the one hand, and insufficient contact between the plates and carbon dioxide on the other hand.
