| 英文摘要 | cds nanoparticles were confined within titanate nanotubes (tnts) by an ion-exchange reaction and a subsequent sulfurization process. prior to the ion-exchange reaction, the exterior surfaces of the tnts were modified by a silane coupling agent to make cds nanoparticles selectively deposit on the inner wall. the composites were characterized by high-resolution transmission electron microscopy, powder x-ray diffraction, inductively coupled plasma atomic emission spectrometry, n-2 adsorption-desorption and uv-vis absorption spectra. the results confirm that cds in the range of 2-3 nm in diameter are confined within the inner cavity of the tnts. cds confined within tnts shows a significant blue-shift of the absorption band edge compared with cds nanoparticles deposited on the exterior surface of tnts. also the tnts-confined cds composite exhibits enhanced photocatalytic activity and photostability for hydrogen evolution under visible light illumination due to the quantum size effect of cds as a result of the spatial confinement effect of the tnts. |
