Promising chemical sensors using tungsten oxide-bismuth vanadium oxide (WO3-BiVO4) as electrode material for 3-methoxypropionitrile (3-MPN) detection |
| 초록 |
This work demonstrates a simple and effective hydrothermal synthesis of tungsten oxide-bismuth vanadium oxide (WO3-BiVO4) which were effectively applied as electrode for the detection of 3-methoxypropionitrile (3-MPN). The morphological observations revealed that the synthesized nanomaterial was comprised of stacked layered nanoplates (LNPs) WO3-BiVO4 with the average diameter of 50-60 nm. The structural and crystalline results revealed the existence of WO3 and BiVO4 crystals, confirming the formation of WO3-BiVO4 LNPs. Electrochemical studies suggested a rapid sensing response towards 3-methoxypropionitrile (3-MPN) chemical through high electrocatalytic activity over the surface of WO3-BiVO4 LNPs modified electrode. The fabricated 3-methoxypropionitrile (3-MPN) chemical sensor based on WO3-BiVO4 LNPs exhibited a high and reproducible sensitivity of ∼605 μAμM-1cm-2 with excellent linear dynamic range (LDR) and correlation efficient of R = ∼0.99502. |
