纺锤状CuO微结构的可控合成与表征
Controllable Synthesis and Characterization of Spindle-Like CuO Micro-structure
摘要
Abstract
Spindle-like CuO micro-sized structures were hydrothermally synthesized using NaOH, urea as precipitant and Cu(NO3)2·3H2O as copper source.The prepared samples were characterized and analyzed by means of XRD, SEM, TEM and HRTEM.The results indicate that the spindle-like CuO exhibited monoclinic phase with high crystallinity.The influence of pH, urea concentration, reaction temperature and reaction time on the growth behavior of CuO was investigated in detail, the results show that the morphology of CuO could be altered by adjusting the relative concentration of NaOH and urea, and thus micro-sized hollow spheres, flower-like structures and spindle-like CuO structures could be obtained.Possible growth mechanism of the spindle-like CuO micro-sized structures was proposed.关键词
