摘要：

In this paper, a new hydrothermal method-discharging-gas method-is introduced. ZnO acicular particles with the ratio of length and diameter 16: 1 are synthesized by the hydrothermal discharging-gas method using a mixed solution of Zn(CPI,COO)(2) with NaNO2 as precursor at 190 degrees C for 1 h. The effects of reaction temperature and precursor concentration on formation of acicular particles are investigated. The results show that the main factor for formation of acicular particles prepared by the hydrothermal discharging-gas method is the extent of crystallinity of ZnO powders before releasing gas.
