PolyU Develops High-Efficiency Carbon Dioxide Electroreduction System for Reducing Carbon Footprint

The Hong Kong Polytechnic University (PolyU) has developed an advanced carbon dioxide (CO2) electroreduction system to efficiently reduce carbon emissions and work towards carbon neutrality objectives. This breakthrough, recently published in Nature Energy and awarded a Gold Medal at the 48th International Exhibition of Inventions Geneva, focuses on converting CO2 into ethylene using an electrocatalytic approach. Led by Prof. Daniel Lau, the research team designed the APMA system, utilizing an alkali-metal-free cell stack with an anion-exchange membrane (AEM) and a proton-exchange membrane (PEM). This system demonstrated a high ethylene specificity of 50%, operating for over 1,000 hours at an industrial-level current of 10A. The innovation also addresses challenges like electrolyte loss and hydrogen formation, making it a promising step towards sustainable and stable ethylene production. The research, in collaboration with the University of Oxford, the National Synchrotron Radiation Research Centre of Taiwan, and Jiangsu University, aims to further enhance product selectivity and explore industry partnerships for green ethylene production, contributing to carbon emission reduction and the pursuit of carbon neutrality goals.
