Ion intercalation dynamics of electrosynthesized mesoporous WO3 thin films studied by multi-scale coupled electrogravimetric methods

Mesoporous WO₃ thin films were prepared electrochemically by using an ionic surfactant during the synthesis, and the electrochemical properties are investigated in comparison with their dense analogues.

Preparation of polyaniline grafted graphene oxide–WO3 nanocomposite and its application as a chromium(iii) chemi-sensor

Polyaniline-grafted-GO@WO₃ was prepared and deposited on a Ag electrode with conducting binders to give a sensor with a fast selective response for Cr³⁺ in the liquid phase. The sensitivity and detection limit are ∼4.4251 mA mM⁻¹ cm⁻² and 0.031 ± 0.010 nM.
