Abstract

The invention provides an electrochemical reactor for the electrochemical reduction of carbon dioxide, the device belongs to a three-chamber reactor, and three diaphragms are separated by two kinds of diaphragms (i.e., an anion-conducting polymer film and a polypropylene film gas diffusion electrode). It is made of transparent plexiglass plate with precision-sized grooves and openings; the three-chamber reactor includes: a gas chamber, a catholyte chamber and an anolyte chamber. The gas chamber includes one side of the polypropylene film gas diffusion electrode polypropylene film, and the catholyte chamber includes one side of the polypropylene film gas diffusion electrode catalyst layer with a silver-based catalyst as the cathode, and the anolyte chamber includes Anode with mixed metal oxide catalyst. The electrochemical reaction device of the present invention adopts organic glass with transparent material, high hardness, alkali resistance and acid resistance as a whole, which is easy for precise processing and assembly, convenient for direct monitoring and observation of electrochemical reaction, and no secondary pollution during the reaction test .

Description

technical field [0001] The present invention relates to the field of electrochemistry, in particular to the electrochemical reduction of carbon dioxide, and more particularly to the electrochemical reduction of carbon dioxide to carbon monoxide. Background technique [0002] The global climate change caused by the massive burning of fossil fuels is intensifying, and the efficiency of greenhouses is becoming more and more serious. Given the current trend, the remaining carbon budget for achieving temperature control goals in the next 10-20 years will be exhausted rapidly, and people need to take immediate action to reduce man-made Factors causing large carbon dioxide emissions. Artificial photosynthesis system capable of simultaneous CO 2 Electrochemical reduction reaction (CO 2 RR) and water oxidation oxygen evolution reaction (OER), which can realize CO 2 Substantial reduction in emissions and large-scale storage of intermittent solar energy in carbonaceous fuels. Howev...
