A photoelectrochemical (PEC) method was constructed for detection of Co²⁺ based on a WO₃/AuNPs/FTO electrode. Gold nanoparticles (AuNPs) were electrochemically deposited on the surface of FTO and then tungsten trioxide (WO₃) with vertically aligned plate-like structure was hydrothermally grown on the surface of AuNPs/FTO. The WO₃/AuNPs/FTO was characterized by scanning electron microscopy and X-ray diffraction (XRD) patterns. From the PEC results, Co²⁺ had a weak inhibition effect on the photocurrent of WO₃/AuNPs/FTO. After addition of ethanol, the photocurrent decreased obviously. On this basis, a sensitive PEC platform was constructed for monitoring Co²⁺ in the range of 0.5-7.0 μmol/L with a detection limit of 0.3 μmol/L. The recovery was from 98.3% to 110.0%, indicating that this method had good accuracy and was expected to be applied to the detection of Co²⁺ in real samples.
