采用表面功能化的C_(60)和Ti(SO_4)_2为起始原料水热制备了C_(60)-TiO_2纳米复合材料.在水热反应过程中功能化C_(60)分子在原位生长的锐钛矿TiO_2纳米粒子表面通过Ti–O–C化学键连作用形成表面配合物,并能抑制TiO_2晶粒的长大.合成的C_(60)-TiO_2纳米复合材料具有比单纯的TiO_2更宽的光谱响应范围、更优的光催化产氢性能和化学稳定性,其在350~550 nm波长范围内均具有光催化产氢活性,且在420和475 nm处的产氢表观量子产率分别为4.2%和8.3%.C_(60)-TiO_2复合材料的可见光催化产氢性能可能归结于其表面配合物的配体-金属电荷转移(LMCT)敏化作用机制. The C 60 Ti 2 O nanocomposites were prepared by hydrothermal reaction of surface-functionalized C 60 and Ti SO 4 _ 2 hydrothermally, and the functionalized C 60 molecules were grown in situ during the hydrothermal reaction Of the anatase TiO 2 nanoparticles formed a surface complex by chemical bonding of Ti-O-C and inhibited the growth of TiO 2 crystal.The synthesized C 60 -TiO 2 nanocomposites were broader than pure TiO 2 , Better photocatalytic hydrogen production and chemical stability, both have photocatalytic hydrogen production activity in the wavelength range from 350 to 550 nm, and the apparent quantum yield of hydrogen at 420 and 475 nm 4.2% and 8.3% respectively.The visible-light catalytic hydrogen production of C_ (60) -TiO_2 composites may be attributed to the ligand-metal charge transfer (LMCT) sensitization mechanism of its surface complexes.
