Tungsten oxide nanowalls nanostructures grown by controlled HFCVD process for electrochemical detection of methylamine solution. |
| 초록 |
In this work, well-defined tungsten oxide (WO3) nano-walls nanostructures were grown on silicon substrate by the controlled hot filament chemical vapor deposition (HF-CVD) process and successfully applied as electrode for electrochemical detection of methylamine chemical. For the growth of WO3 thin film, the temperature of Tungsten (W) wire was kept constant at 1450 oC and then performed the gasification followed by heating of W wire using different substrate temperatures ranging from 350oC - 450oC. The morphological characterization evidenced that well-defined and highly dense nano-walls like structures were grown on Si substrate when the substrate temperature was 400oC. The grown WO3 films with classic monoclinic crystal structures and good crystal quality confirmed by observing the structural, crystalline and compositional characterizations. The cyclovoltammetry and linear sweep analysis were shown sensing behavior of the grown WO3 film towards the methylamine. |
