Can carbon dioxide be used to make clothes and perfume? Can it still be made into LEGO toys? Technology has changed the world beyond imagination. On May 3rd, the journal Nature published the latest research results of a research team in China. This study has achieved efficient preparation of acetic acid (also known as acetic acid) using carbon dioxide as raw material, found a new path for green production of acetic acid, and unveiled a corner of the dream of "zero carbon" manufacturing. Mai Liqiang, one of the authors of the above achievement paper and professor of the School of Materials Science and Engineering of Wuhan University of Technology, introduced the latest research of his team, together with Professor Pang Yuanjie's team and the research team of the University of Toronto, "limiting the conformation of the carbon dioxide adsorption group to complete the electroreduction of carbon monoxide to acetate", using low-grade renewable power and carbon dioxide catalytic electrolysis, Convert carbon dioxide into high value-added carbon based fuels or chemicals. This achievement is crucial for the conversion and storage of renewable energy and the mitigation of climate change, and its strategic significance is very important. In this research work, my research team reported a new type of diluted alloy catalyst that can efficiently reduce carbon monoxide to acetic acid using electrical energy under high pressure and strong reaction conditions. Its reaction has the highest selectivity (Faraday efficiency) of 91%, which is similar to the selectivity of electric reduction from carbon dioxide to carbon monoxide, achieving the conversion and storage of renewable energy. Copper based catalysts are one of the most efficient catalysts in carbon dioxide electrocatalytic reduction reactions. Although copper based catalysts can efficiently catalyze carbon carbon coupling steps, the selectivity of each multi carbon product is not high. For this purpose, the research work designed a copper silver dilution alloy catalyst, which dispersed copper at the atomic level in the silver substrate, with only 2 to 4 atoms at the copper site. This forces the carbon groups to enter a "monodentate" adsorption state, efficiently directing the reaction into the acetic acid generation pathway. However, small copper sites may not be able to efficiently complete the carbon carbon coupling step, requiring higher reactant molecular coverage. Therefore, a high pressure and strong three-phase interfacial reaction device was designed in this study, which can maintain gas-liquid two-phase equilibrium under high pressure, so as to react stably and meet the demand for molecular coverage of reactants on the catalyst surface. This study used advanced in-situ Raman spectroscopy technology from Wuhan University of Technology to demonstrate a key intermediate in the CO reduction process, namely the C=C=O or (OH) C=COH configuration, providing a theoretical basis for the subsequent design of more efficient catalysts. The economic and technological feasibility analysis shows that this technology has broad prospects for future application. It is reported that this study confirms the potential application of carbon dioxide electro reduction technology in distributed clean energy storage and the feasibility of using carbon dioxide electro catalytic conversion technology for green synthesis of carbon based chemicals. A number of indicators have broken the world record. As an important organic chemical raw material, acetic acid needs to be widely used to manufacture chemical fiber clothing, perfume fragrance, plastic processing products, etc. The traditional method of producing acetic acid is usually through chemical synthesis or starch fermentation, with each kilogram of acetic acid produced using these methods emitting approximately 1.6 kilograms of carbon dioxide
