▎ 摘  要

NOVELTY - Graphite of alkenyl bipolar membrane, comprises bipolar membrane which is a composite film comprising sequentially connected Nafion (Sulfonated tetrafluoroethylene) film layer, graphene oxide layer and alkaline film layer. The alkaline film layer is polyvinyl alcohol, and chitosan film layer formed by cross-linking between the polydimethyl diallyl ammonium chloride and the glutaraldehyde. USE - The graphite is useful in electrochemical reduction of carbon dioxide. ADVANTAGE - The graphite of alkenyl bipolar membrane solves the problem that the liquid product in the electrochemical reduction carbon monoxide field under the action of bias, from the negative electrode chamber to the positive electrode (loss). The prepared bipolar membrane can inhibit the penetration of any ion between the cathode and anode, so it can effectively prevent the liquid products of the carbon dioxide reduction on the positive electrodes of the negative electrodes. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for the preparation method graphite alkenyl bipolar membrane.
