Core Viewpoint - The research team from Dalian Institute of Chemical Physics and the University of Trieste has made significant progress in photocatalytic hydrogen cleavage, achieving this process at room temperature, as published in the journal "Science" on September 5 [1][3]. Group 1: Hydrogenation Reaction - Hydrogenation reactions are crucial in the chemical industry, with approximately one-quarter of chemical processes involving at least one hydrogenation step [3]. - A key step in hydrogenation is hydrogen activation, which includes both homolytic and heterolytic cleavage mechanisms [3]. - Heterolytic cleavage of hydrogen gas produces active hydrogen species, which can enhance the generation rate of important chemical products and reduce side reactions [3]. Group 2: Challenges and Innovations - Traditional hydrogen cleavage typically requires high temperatures and pressures, increasing energy consumption and safety risks due to hydrogen's explosive nature [3]. - The research team proposed a method utilizing photogenerated electrons and holes to create spatially adjacent positive and negative charge centers, enabling efficient hydrogen cleavage at room temperature [5]. Group 3: Environmental Impact and Future Directions - Using 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, promoting the optimization of carbon resource utilization [5]. - The research team aims to further investigate 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 industries [5].
