| 摘 要： | 以CuCl2·3H2O，Cu（CH3COO）2·H2O和CuSO4·5H2O作为铜源，并向反应体系中引入少量NaCl或NaNO3，通过乙二醇溶剂中的溶剂热反应，合成了形貌各异的CuS微晶．结合XRD和SEM表征，初步探讨了阴离子Cl-、CH3COO-、SO4^2-和阳离子Na’对CuS微晶生长过程的影响．结果表明，Na＋对CuS微晶的生长过程没有显著影响，而Cl、CH3COO-、SO4^2-由于在{1012}晶面上选择性吸附能力的差异，显著影响CuS微晶的形貌．本研究为进一步有效调控CuS微晶的形貌及性能奠定了基础．

| Abstract: | CuS microcrystals with unique structures can be synthesized by a solvothermal reaction in ethylene glycol by using CuCl2·3H2O, Cu（CH3COO）2·H2O or CuSO4·5H2O as copper sources or adding NaNO3 or NaC1 into the reaction system. Effects of anions such as CI-, CH3COO-, SO4^2-and cation Na＋ on the growth of CuS microcrystals have been discussed. Itwas found that Na＋ had little effect on the morphology of CuS microcrystals, but remarkable effects can be observed when CI-, CH3COO-, SO4^2- were used due to the difference of selective adsorption on { 1012 } crystal planes, which may provide convenient routes for effective control on the architectures of CuS microcrystals. |
