Dual-Modal Photoelectrochemical and Visualized Detection of Copper Ions.

ABSTRACT: Copper is one of the extensively utilized heavy metals in modern industry and can be easily released into the environment due to high solubility of copper ions (Cu²⁺). Its percolation in water and accumulation along the food chain pose a serious threat to human health. Hence, it is of great significance to explore a novel, facile, and sensitive detection method for Cu²⁺. Based on the intriguing photo-to-electricity conversion process of CdS QDs, as well as desirable electrochromic property of WO₃ NFs, a dual-modal photoelectrochemical (PEC) and visualized detection platform for Cu²⁺ is fabricated. The electrochromic WO₃ NFs act as a display for the Cu²⁺ concentration, of which the color change could be observed directly by t
