[Plastic Hardware Network] The research team of the Fujian Institute of Physics, Chinese Academy of Sciences recently synthesized a new type of palladium nano-catalyst using Cu(II) ion-assisted in-situ reduction at room temperature. The catalyst has an ultra-low precious metal loading (about 0.1%) and excellent performance. , Long life, can greatly reduce the cost of catalysts and save a lot of precious metal resources. After the catalyst is successfully prepared, it is expected to form a new generation of coal-to-ethylene glycol catalyst technology. Coal-to-ethylene glycol technology can not only effectively alleviate the contradiction between the supply and demand of ethylene glycol in my country, but also improve the level of efficient and clean conversion and utilization of coal resources. The reaction of CO gas-phase oxidative coupling to dimethyl oxalate is a key step in the production of ethylene glycol from coal. The currently used catalysts have a relatively high loading of palladium, which greatly increases the cost of the catalyst. More related information:
