摘要:

采用类水滑石型混合金属氢氧化物(CdCr-LDH和ZnCdCr-LDH)为前驱体, 通过气-固反应方法, 制备了根植于层状氢氧化物层板中的硫化镉纳米晶和硫化镉/硫化锌复合纳米晶, 通过改变前驱体(CdCr-LDH)中镉和铬的摩尔比可以调控硫化镉纳米晶的粒径.

关键词: 含铬水滑石; 硫化镉; 硫化锌; 纳米晶

Abstract:

The layered double hydroxide(LDH) compounds Cd 0.7 Cr 0.3(OH)2(C12H25SO4)0.3·0.7H2O and Zn 0.5 Cd 0.25 Cr 0.25 (OH)2(C12H25SO4) 0.25 ·1.7H2O were synthesized. Using these compounds as the precursors, we prepared CdS and CdS/ZnS nanocrystals that are implanted and stabilized in the layer matrices of the two types of compounds via a gas/solid reaction. The size of the nanocrystals can be controlled and tuned by changing the Cd/Cr molar ratio in the precursor.

Key words: Cr-contained hydrotalcite; Cadmium sulfide; Zinc sulfide; Nanocrystals
