Innovative structural encapsulation method opens up new ways: carbon dioxide is successfully converted into ethanol

News on May 17th, according to official disclosures from Jiangnan University, Professor Liu Xiaohao’s team from the School of Chemistry and Materials Engineering of the school successfully innovated and constructed a nanoscale “water storage” membrane reactor using the structural encapsulation method. Internationally, this important achievement achieved nearly 100% carbon dioxide conversion rate, directly converting it into ethanol, and achieved it under mild conditions.

According to reports, in the nanometer "water storage" membrane reactor constructed by Professor Liu Xiaohao's team, the structure of the catalyst is similar to a capsule, with dispersed ceria carriers and double palladium catalysts encapsulated inside. The shell of this capsule is highly selectively designed, and after hydrophobic modification, it can ensure that the water generated inside is enriched, and the generated ethanol can escape smoothly. The presence of water can stabilize the double palladium active site, thereby achieving efficient and stable conversion of carbon dioxide into ethanol under mild conditions (3MPa, 240°C). It is worth mentioning that the innovative dual-palladium active site has a unique geometry and electronic structure, which can realize the directional hydrogenation of carbon dioxide to produce a single high-value product, ethanol.

According to ITBEAR Technology Information, prior to this, in 2016, a research team led by chemist Adam Rodinon of the Oak Ridge National Laboratory in the United States accidentally discovered that a certain Under catalyst conditions, carbon dioxide and water can be converted into ethanol and oxygen at room temperature, with a conversion rate of 63%. The research team led by Professor Liu Xiaohao achieved almost 100% conversion rate, creating a historical record for Chinese scientific research teams.

The significant scientific achievement has been published in the journal "ACS Catalysis" and has garnered widespread attention.. The successful development of this technology will provide a new way to convert and utilize carbon dioxide, and is expected to have a positive impact on solving global problems such as greenhouse gas emissions and energy crises. In the future, the team will continue to conduct in-depth research to further promote the practical application and industrialization of this technology and make greater contributions to sustainable development.
