Monoclinic WO3 nanosheets-carbon nanotubes nanocomposite based electrochemical sensor for sensitive detection of bisphenol A

•WO3-CNT nanocomposite was hydrothermally prepared and used as a novel sensing material.•WO3-CNT/GCE has enhanced electro-oxidation peak current and reduced potential for BPA.•Improved surface area, good electron transfer and reproducibility of the sensor.•WO3-CNT/GCE sensor for BPA has two linear ranges with low detection limit (16.3 nM)•Admirable performance of the sensor for the practical applicability in real samples.
