The raspberry-like strontium tungstate microspheres supported on reduced graphene oxide nanosheets (rGOSs@SrWO 4 ) were prepared by a hydrothermal method and it was applied to the electrocatalytic sensing of catechol. The as-prepared rGOSs@SrWO 4 composite was characterized by XRD, Raman, FESEM, EDX, EIS, and voltammetric techniques. Morphology studies reveal the uniform wrapping of raspberry- like SrWO 4 microstructure by thin sheets of rGOSs and the composite possesses large surface area and abundant catalytic active sites. The rGOSs@SrWO 4 composite modified screen-printed multi-conventional electrode (SPME) was fabricated which was found to exhibit extraordinary electrocatalytic activity and ex- cellent selectivity towards the detection of catechol. The rGOSs@SrWO 4 /SPME displayed a linear range of 0.034–672.64 μM and detection limit of 7.34 nM using differential pulse voltammetry as signal read-out. Furthermore, the electrode was durable, reproducible and repeatable. The practical utility of the method was demonstrated in green tea and drinking water samples.
