研究了在180℃水热条件下,Zn(NO3)2.6H2O与NaOH、氢氧化四丙基铵(TPAOH)、氢氧化四甲基铵(TMAOH)3种不同OH-源在不同[OH-]/[Zn2+]比例下制备的ZnO的形貌变化。扫描(SEM)照片表明,在[OH-]/[Zn2+]为2时,采用NaOH时,ZnO主要为球形颗粒,直径为200~500nm,而采用TPAOH时为梭形,采用TMAOH时为花形;[OH-]/[Zn2+]为4时,3种OH-源的ZnO产品都为薄片状;[OH-]/[Zn2+]为8时,采用NaOH的产品为不同直径大小ZnO棒组成的辐射状球形,而采用TPAOH和TMAOH的ZnO都是由短柱状组成的花形,大小在1μm以下。
The effects of Zn (NO3) 2.6H2O, NaOH, tetrapropylammonium hydroxide (TPAOH) and tetramethylammonium hydroxide (TMAOH) / [Zn2 +] ratio prepared ZnO morphology changes. Scanning electron microscopy (SEM) images showed that when NaOH was used, the size of ZnO was mainly spherical particles with a diameter of 200 ~ 500nm when using [OH -] / [Zn2 +] 2 and fusiform when using TPAOH and shaped with TMAOH. When [OH -] / [Zn2 +] was 4, all the three kinds of OH-source ZnO products were flaky. When [OH -] / [Zn2 +] was 8, the products using NaOH were composed of ZnO rods with different diameters Spherical shape, while the use of TPAOH and TMAOH ZnO are short columnar flower shape, the size of 1μm or less.
