Abstract

The invention discloses a nitrogen doped TiO2 modified glass-carbon electrode, a preparation method and applications thereof. The preparation method comprises steps of preprocessing a glass-carbon electrode, preparing nitrogen doped TiO2, and preparing a N-TiO2 modified glass-carbon electrode. Nitrogen doped TiO2 is prepared through a solvothermal method and is used to modify a glass-carbon electrode so as to form a nitrogen doped TiO2 modified glass-carbon electrode. The nitrogen doped TiO2 modified glass-carbon electrode can be soaked in a critic acid-sodium citrate buffer solution with a pH value of 5.6, then cyclic voltammetry is used to research the electrochemical behavior of vitamin B2 in a modified electrode and a naked electrode, compared with a naked glass-carbon electrode, the nitrogen doped TiO2 modified glass-carbon electrode has a good catalytic performance, the oxidation-reduction current strength is prominently enhanced, and reversible diffusion of current is realized.

Description

technical field [0001] The invention relates to the technical field of electrochemical materials, in particular to a nitrogen-doped TiO 2 Modified glassy carbon electrode and preparation method thereof, also relates to the nitrogen-doped TiO 2 Modified glassy carbon electrode in vitamin B 2 application of content measurement. Background technique [0002] Vitamin B 2 It is one of the essential nutrients for the human body.
