文摘

Octahedral CdS hollow microcages were synthesized on the basis of the ion interface reaction process byusing CdMoO₄ crystals as in situ sacrificial templates. The products were characterized by X-ray powderdiffraction, 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 constructedby nanoparticles or nanoplates with Na₂S or thioacetamide as the sulfur source, respectively. The methodusing metal salts as the sacrificial template to prepare a hollow structure can be widely applied to synthesizeother chalcogenides.
