我国科研团队实现常温氢气异裂

Group 1 - The research team from Dalian Institute of Chemical Physics and the University of Trieste has made progress in photocatalytic hydrogen cleavage, achieving hydrogen cleavage at room temperature [1][3] - Hydrogenation reactions are crucial in the chemical industry, with about one-quarter of chemical processes involving at least one hydrogenation step [3] - Hydrogen cleavage can enhance the production rate of important chemical products and reduce side reactions, but it typically requires high temperature and pressure, increasing energy consumption and safety risks [3] Group 2 - The research proposes using photogenerated electrons and holes to create spatially adjacent positive and negative charge centers for efficient hydrogen cleavage at room temperature [5] - Utilizing hydrogen and carbon dioxide as raw materials to produce high-value products like ethane and ethylene can significantly lower energy consumption and reduce carbon dioxide emissions [5] - The research team aims to further study reaction processes and develop industrial technology pathways that couple light and thermal energy, providing new models for the upgrading and transformation of modern coal chemical industry [5]
