ZnO是一种重要的宽禁带化合物半导体材料，通过沿着其快速生长方向调节生长速率，可以得到多种新颖的结构。利用胶体晶体模板法制备高度有序的大孔材料在光子晶体、催化剂等领域有着广泛的应用前景。本研究采用不同的电化学方法制备了具有高度有序多孔结构的氧化锌。通过不同官能团的胶体晶体可以制备出纳米网、反蛋白石结构和具有孔阵列的球形/椭球形颗粒。研究了模板剂对不同表面基团的大孔结构形貌的影响。所有的纳米网都是由没有官能团的胶体晶体沿{111}面沿着生长。具有羟基的胶体晶体诱导纳米网的无序排列。羧基模板法制备的反蛋白石结构表面更光滑。
ZnO is an important wide bandgap compound semiconducting material and exhibits a wide range of novel structures that can be grown by tuning the growth rates along its fast growth directions. Highly ordered macroporous materials by using colloidal crystal template method are of great interest in many fields including photonic crystals and catalysts. In this study, ZnO with highly ordered porous structure was deposited by different electrochemical method. Nanomeshes, inverse opal structures, and spherical/ellipsoidal particles with pore arrays are fabricated by the colloidal crystals with different functional groups. The template effects on the morphology of the macroporous structures for different surface groups are studied. All the nanomeshes grows along the {111} plane family by colloidal crystals without functional groups. Disordered arrangements of the nanomeshes are induced by colloidal crystals with hydroxyl groups. The inverse opal structures fabricated by template with carboxyl groups are smoother in surface.
