【新华社】让氢气“更听话”！科学家在光催化氢气异裂领域取得新进展

Core Insights - Hydrogen is a key element in transforming nitrogen into fertilizers and converting carbon dioxide into gasoline, but its dissociation at room temperature has been challenging [1] - A research team from the Dalian Institute of Chemical Physics and the University of Trieste has made progress in photocatalytic hydrogen dissociation at room temperature, with results published in the journal Science [1][2] Group 1: Research Breakthroughs - The team developed a photocatalytic strategy that utilizes spatially adjacent positive and negative charge centers to achieve hydrogen dissociation at room temperature [2] - By using gold/titanium dioxide as a model catalyst, the team induced electron migration and captured holes at the catalyst interface, forming bound electron-hole pairs that enhance hydrogen dissociation efficiency [2] Group 2: Applications and Future Directions - The hydrogen species produced can convert inert carbon dioxide into ethane at room temperature, with the catalyst maintaining stable operation for over 1500 hours [2] - The process of producing high-value products like ethane and ethylene from hydrogen and carbon dioxide can significantly reduce energy consumption and carbon dioxide emissions, aiding in the optimization of carbon resource utilization [3] - Future research will focus on developing industrial technology pathways that couple light and thermal energy for the upgrading and transformation of modern coal chemical processes [3]
