A mesoporous silica film (MSF) with vertically oriented mesochannels on a conductive substrate serves as a hard-template for electrodeposition of polyaniline (PANI). The PANI nanostructures thus prepared are orderly confined in silica mesochannels, eventually producing a robust hybrid film. The film displays a good electrocatalytic activity toward oxidation of ascorbic acid, and can be used for potentiometric pH sensing with a Nernstian response.
一种在导电基底上具有垂直取向介孔通道的介孔二氧化硅膜（MSF）用作聚苯胺（PANI）电沉积的硬模板。由此制备的聚苯胺纳米结构有序地限制在二氧化硅介孔通道中，最终形成一种坚固的混合膜。该膜对抗坏血酸的氧化表现出良好的电催化活性，可用于具有能斯特响应的电位pH传感。
