  2. Using v2 & 5 and alkylamines ( cs - cao alkyl chain ) as precursor, vanadium oxide nanotubes which have an unique structure that alkylamines intercalate into layers of tubes wall affecting the layer spacing were prepared. their layers spacing ranges from 1. 25 nm to 3. 82 nm according to the length of alkyl chain. moreover, the growth mechanism of vanadium oxide nanotubes have been investigated and 3 - 2 - id model was established to interpret the vanadium oxide nanotubes growth process. potassium niobate is a functional materials which can be used as photochemical catalysts. lt is well known that the catalytic activites are affected greatly by the surface area of catalyst particles on which the reaction take place

    以系列烷基胺和五氧化二釩為原材料，通過簡單的水熱反應合成出了氧化釩納米管，這種納米管結構獨特，烷基胺作為模板劑內嵌入納米管管壁層間，成為支持納米管的骨架，並影響層間距大小，納米管管壁層間距隨著烷基胺碳鏈長度的不同在很大范圍內變化，通過採用不同碳鏈長度的烷基胺（ c _ nh _ （ 2n + 1 ） nh _ 23 n 20 ）作為模板，來控制氧化釩納米管的層間距，層間距可調控范圍從1 . 25nm到3 . 82nm 。
