Fabrication of an ultra-sensitive para-nitrophenol sensor based on facile Zn-doped Er2O3 nanocomposites via an electrochemical approach

Abstract

Semiconductor doped Zn-doped Er₂O₃ nano-composite materials were prepared via a wet-chemical technique in a single-step at alkaline pH to develop a selective and sensitive para-nitrophenol capturing electrochemical probe for environmental remediation.
