Shulou(Shulou.com)11/24 Report--

Thanks to CTOnews.com netizen Xiao Zhan for the clue delivery! CTOnews.com May 17, according to the official news of Jiangnan University, the team of Professor Liu Xiaohao of the School of Chemistry and Materials Engineering of Jiangnan University creatively adopted the structural encapsulation method to build a nano-"water storage" membrane reactor, which achieved nearly 100% conversion of carbon dioxide to ethanol under mild conditions for the first time in the world.

According to reports, the nano-"water storage" membrane reactor built by the scientific research team has a catalyst structure similar to that of a capsule and encapsulates a double palladium catalyst dispersed on cerium dioxide carrier. Liu Xiaohao introduced that the shell of the capsule has high selectivity. After hydrophobic modification, it ensures that the water generated inside is enriched and the product ethanol can overflow. The water environment can stabilize the double palladium active sites, and the catalyst can achieve nearly 100% selective and stable conversion of carbon dioxide to ethanol under mild conditions. It is worth mentioning that the double palladium active site constructed by this study has a unique geometric and electronic structure, which can realize the directional hydrogenation of carbon dioxide to a single high-value product ethanol.

▲ Tu Yuan related research results of Jiangnan University were published in American Chemical Society Catalysis.

CTOnews.com query learned that as early as 2016, a research team led by Adam Rodinon, a chemist at Oak Ridge National Laboratory in the United States, accidentally found that carbon dioxide + water could be converted into ethanol + oxygen at room temperature under certain catalyst conditions, with a conversion rate of 63%. China's scientific research team has achieved nearly 100% transformation for the first time.
