在水溶液中用三联吡啶氯化钌[Ru(bpy)32+]敏化铁纳米粒子,三乙胺(TEA)作为牺牲剂,形成光催化分解水制氢体系。体系中除了三乙胺以外没有使用任何有机溶剂。催化剂铁纳米粒子为非贵金属并且可以循环利用。此外,光敏剂[Ru(bpy)32+]的吸收在可见光区,有效地利用了太阳光。该结果为研究可见光区光催化分解水体系提供了新思路。 Ternary pyridine ruthenium (Ru (bpy) 32+] sensitized iron nanoparticles and triethylamine (TEA) were used as sacrificial agent in aqueous solution to form photocatalytic decomposition water to produce hydrogen. No organic solvents other than triethylamine were used in the system. Catalyst iron nanoparticles are non-precious metals and can be recycled. In addition, the absorption of the photosensitizer [Ru (bpy) 32+] effectively utilizes sunlight in the visible region. The results provide a new idea for the study of visible light photocatalytic decomposition of water system.
