A proof-of-concept electroreduction-free anodic stripping voltammetry analysis of Ag(i) based on S,N–Ti3C2Tx MXene nanoribbons

Abstract

Herein, by preparing sulfur and nitrogen co-doped Ti₃C₂T_x MXene nanoribbons (S,N–Ti₃C₂T_xR) as a sensing material, a sensitive and novel electroreduction-free anodic stripping voltammetry strategy was designed to detect Ag(I) (Ag⁺) for the first time, which can successfully avoid the power-consuming electroreduction step, achieving simple, sensitive and efficient detection for Ag⁺ with a low detection limit and wide linearity.
