A proof-of-concept electroreduction-free anodic stripping voltammetry analysis of Ag(I) based on S,N-Ti 3 C 2 T x MXene nanoribbons.

Herein, by preparing sulfur and nitrogen co-doped Ti 3 C 2 T x MXene nanoribbons (S,N-Ti 3 C 2 T x R) 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.
