In Situ Sacrificial Template Approach to the Synthesis of Octahedral CdS Microcages

摘要

Octahedral CdS hollow microcages were synthesized on the basis of the ion interface reaction process by using CdMoO4 crystals as in situ sacrificial templates. The products were characterized by X-ray powder diffraction, transmission electron microscopy, field-emission scanning electron microscopy, and a Brunauer-Emmett-Teller plot. The results show that the shells of the obtained octahedral CdS microcage are constructed by nanoparticles or nanoplates with Na2S or thioacetamide as the sulfur source, respectively. The method using metal salts as the sacrificial template to prepare a hollow structure can be widely applied to synthesize other chalcogenides.
