水热法合成Mnx Zn1-xO微晶体
Hydrothermal Synthesis of MnxZn1-xO Microcrystal
摘要
Abstract
MnxZn1-xO crystal was synthesized by hydrothermal method in this work. The experimental parameters for hydrothermal synthesis were:mineralizer concentration 3mol·L-1KOH, the fill factor 35%, temperature 430℃, Zn(OH)2 doped with MnO2 used as precursor, and the reaction time 24 hours. The Mn concentration in crystal was determined by X-ray EDS. The atomic percentage of Mn in crystal increases as the concentration of MnO2 in precursor increased. The maximum atomic percentage for Mn is over 2%. The morphology shows characteristics of hexagonal prism of pure ZnO crystal. The exposed faces are hexagonal faces m{1010}, hexagonal cone faces p{1011}, negative polar faces {0001}and positive polar faces{0001}. The diameters of the crystals are 50-200μm,the heights are 20-100μm.关键词
