以二维和三维聚苯乙烯蛋白石为模板，采用电沉积法在铟锡氧化物涂层玻璃上制备了二维和三维有序多孔氧化锌（ZnO）薄膜。该氧化物是由过氧化氢在高氯酸锌水溶液中的电化学还原形成的。扫描电子显微镜测量结果表明，有序的大孔氧化锌反蛋白石结构。在高过氧化氢浓度下，实现了2D和3D结构的致密内部保形填充。通过X射线衍射检查纳米晶ZnO的形成。（© 2008 WILEY‐VCH Verlag GmbH & Co. KGaA，魏因海姆）
Two‐ and three‐dimensional ordered porous zinc oxide (ZnO) films were prepared by electrodeposition on Indium Tin Oxide coated glass, using two‐ and three‐dimensional poly(styrene) opal templates. The oxide was formed by electrochemical reduction of hydrogen peroxide in aqueous zinc perchlorate solution. Scanning electron microscopy measurements showed well ordered inverse opal structures for macroporous ZnO. At high hydrogen peroxide concentration, dense inner conformal filling was achieved for 2D and 3D structures. The formation of nanocrystalline ZnO was checked by X‐ray diffraction.
