Studies on electronic chemical CO2 conversion systems that can utilize useful chemicals through conventional pollutant processes are essential for building a carbon-neutral society by eliminating CO2 without polluting the environment, although significant progress has been made through the most relevant studies so far. . They are in the lab itself. Indeed, industrial applications still have many constraints, such as the scaling and development of suitable catalysts and electrons.
Korea Institute of Science and Technology (KIST)Dr. Hyung-suk Oh, Dr. A research team at the Clean Energy Research Center led by Eun-Jung Huang and Dr. Wang-Hui Li has developed a marine arch-shaped nano-copper catalyst for a high ocean. Efficiency Electronic chemical CO2 conversion systems that deliver ethylene and ethanol, as well as related systems related to the mass production of catalysts.
The USIN-shaped catalyst is capable of producing a wide variety of ethylene, developed by research teams at KIST, including plastics, synthetic rubber and building materials, which are used to make a variety of everyday products. The catalyst features an array of irregularly shaped needles and looks like sea urchins. This unique design enables enhanced catalytic activity through sharp needle tips. Compared to conventional copper catalysts, the use of this catalyst leads to higher selective ethylene production at lower voltages, increasing the yield of ethylene by more than 50%. Also, the establishment of a large production system by stacking several layers of CO2 conversion cells confirms the possibility of commercialization of the catalyst.
The research team performed various real-time (in situ / operando) analyzes to observe the chemical properties of the catalyst during the reaction. Their results confirm that the high copper hydroxide and copper oxide content increased the carbon dioxide conversion efficiency due to the alkaline components added to the team catalysts. Based on their research, it was discovered that increasing the ratio of copper hydroxide and copper oxide during the reaction is the key to increasing the efficiency of ethylene production, which presents the design direction of the catalyst in future studies.
Dr. Kist. Hyung-suk Oh said, “This study has increased the efficiency and scale of the electronic chemical CO2 conversion system through the development of marine urine-sized nano-copper catalysts with alkaline substances associated with large-scale conversion applications.” In our bottles. He added that the results of this study are expected to make a significant contribution to the commercialization of electronic chemical carbon dioxide conversion systems.
