Preparation method of gold-titanium dioxide composite nano-tube array and gold nano-tube array electrode

The invention discloses a preparation method of a gold-titanium dioxide composite nano-tube array and gold nano-tube array electrode. The preparation method comprises the following steps: (1) preparing a rectangular titanium metal sheet; (2) electrolyzing; (3) quenching; (4) manufacturing an electrode; (5) electroplating; (6) washing; (7) repeating the step (5) and the step (6); (8) impregnating filter paper with hydrofluoric acid and arranging the electroplated electrode on the filter paper; and (9) repeating the step (5) and the step (6). The preparation method can be used for preparing a highly ordered Au/Au-TiO2 nano-tube array electrode material with controllable morphology, pipe diameter and wall thickness. 本发明公开种金-二氧化钛复合纳米管阵列与金纳米管阵列电极的制备方法，包括如下步骤：(1)准备矩形钛金属片；(2)电解；(3)淬火；(4)制作电极；(5)电镀；(6)清洗；(7)重复步骤(5)和步骤(6)；(8)使用氢氟酸浸润滤纸，将电镀后的电极置于滤纸之上；(9)重复步骤(5)和步骤(6)。本发明能够制备出形貌、管径、壁厚可控的高度有序的Au/Au-TiO2纳米管阵列电极材料。
