A facile and efficient strategy for photoelectrochemical detection of cadmium ions based on in situ electrodeposition of CdSe clusters on TiO₂ nanotubes

An efficient protocol for selective and sensitive detection of Cd²⁺ was first developed based on photocurrents obtained at CdSe clusters which are in situ electrodeposited on TiO₂ nanotubes with the gradual addition of Cd²⁺, with theoretical and technical simplicity, and further successfully applied to an assay of Cd²⁺ in tap and lake water samples.
