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

Abstract

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.
