摘要

CdSiobate composite synthesized by exfoliation/self-assembly processing was first reported. The processing presents two steps, namely (i) restacking of [Ca_2Nb_3O_(10)]_n~(n-) nanosheets in Cd(NH_3)_4~(2+) solution and (ii) forming of CdSiobate composite by adding Na_2S to the (i) reacting system. The as-prepared composite of CdSiobate can be indexed to tetrahedral symmetry (lattice parameters, a 5.462(5) ?; c 17.3303(1) ?) on basis of X-Ray powder diffraction result. The scanning electron microscope and energy dispersive spectrometer observation demonstrates the uniform distributions of Ca, Nb, O, Cd, and S elements in the particles. The UV-vis absorption edge of the CdSiobate composite (CdS coated with host niobate) shows blue shift (shifts to high energy) compared with that of the uncoated CdS particles.
