| Popis: | Here, we have successfully synthesised β-SnWO4 Nps via simple and low-cost co-precipitation method. XRD pattern confirms the wolframite cubic structure of β-SnWO4 Nps which is belonging to P213 or T4 space group with an average crystallite size of ~38 nm. FTIR spectrum of β-SnWO4 Nps shows the bands at 620–825 cm−1 is assigned to characteristical stretching and bending vibrational modes of WO 6 6 , W–W bonds and stretching vibration of W–O–W bridging bonds in β-SnWO4. UV-DRS spectrum shows the strong absorption band edge at 604 nm and the estimated bandgap of β-SnWO4 Nps is found to be 1.9 eV. The β-SnWO4 shows excellent photocatalytic activity against indigo carminedye under various conditions of β-SnWO4 Nps. In addition to this, the electrochemical senor performance toward the quantification of dopamine at nanomolar concentration and anode material for Li-ion batteries by showing high reversible discharge/charge capacity was explored. |
