环糊精对光催化制氢体系的影响

Effect of Cyclodextrins on Photocatalytic Hydrogen Production System

将环糊精应用于以铁氢化酶为催化剂,有机染料酸性红为光敏剂的均相制氢体系中,可提高铁氢化酶和光敏剂的水溶性和稳定性,从而提高了体系光催化制氢效率。在此光催化体系中所用催化剂铁氢化酶和光敏剂酸性红均不含有贵金属,除牺牲剂三乙胺外没有使用任何有机溶剂,为研究廉价和水溶性光催化制氢体系提供了新思路。

Application of cyclodextrins in homogeneous hydrogen production system with Fe-hydrogenase as catalyst and organic dye acid red as photosensitizer can increase the efficiency of hydrogen production system by improving water solubility and stability of Fe-hydrogenase and photosensitizer. Both the photosensitizer and the catalyst don’t contain noble metal. Except for TEA, the hydrogen production system does not use other organic solvent. The result can provide a new way to construct a noble-metal-free system for photocatalytic hydrogen production in aqueous solution.
