Abstract

The invention belongs to the technical field of preparation of electrochemical sensors, and specifically discloses an electrochemical sensor with self-cleaning ability, including an electrode core and a new composite material based on MTOF (M refers to doped metal elements), and the composite material is attached to on the surface of the electrode core. The preparation method of the sensor is simple, time-saving, low-cost, and environmentally friendly, especially the polymer and the residue of the detected substance attached to the surface of the electrode core after detection can be oxidized under the conditions of ultraviolet light and visible light. The regeneration and self-cleaning effect of the electrochemical sensor under visible light can be achieved. The electrochemical sensing platform regenerated under visible light not only reduces the cumbersome procedures of electrode grinding and modification, but also saves the cost of modification materials, and the descaling and regeneration of electrodes prolongs the service life of electrodes. It is used for the simultaneous detection of environmental pollutants hydroquinone and catechol, with simple operation, good selectivity, high sensitivity and low detection limit.
