Hydrothermal Synthesis of Cr₂Se₃ Hexagons for Sensitive and Low-level Detection of 4-Nitrophenol in Water.

ABSTRACT: We report a simple hydrothermal method used for the synthesis of Cr₂Se₃ hexagons (h-Cr₂Se₃) and its application towards electrochemical sensing of 4-nitrophenol (4-NP). The formation of h-Cr₂Se₃ was confirmed by using scanning electron microscopy, energy dispersive X-ray spectroscopy, X-ray diffraction, and X-ray photoelectron spectroscopy. The electrochemical activity of the h-Cr₂Se₃ modified screen-printed carbon electrode (SPCE) towards 4-NP was studied using cyclic voltammetry (CV) and amperometric i-t techniques. Typically, the obtained results were compared with those for a bare SPCE. The CV result clearly reveals that h-Cr₂Se₃ modified SPCE has higher catalytic activity towa
