Novel durian-like TiO
2 @CdS core-shell particles were synthesized through a solvothermal method in ethylenediamine solution and the obtained nanocomposites were characterized by scanning electron microscopy (SEM), powder X-ray diffraction (XRD), and transmission electron microscopic (TEM) techniques. It can be seen from the characterization that the synthesized core-shell structured particles show uniform size. The possible formation mechanism of TiO2 @CdS core-shell particles is also presented schematically. CdS grows on the TiO2 surface in the form of nanorods, turning the TiO2 @CdS composite particles into durian-like structures. The durian-like TiO2 @CdS core-shell particles prepared in the experiment can overcome the disadvantages of TiO2 and CdS, respectively. They not only produce a higher yield of H2 than pure TiO2 ; the durian-like TiO2 @CdS nanostructures formed at 180 °C for 16 h produced 2.5 times as much H2 as did TiO2 , also showing enhanced stability as compared with pure CdS.
