METHOD OF MANUFACTURING A CHEMORESISTOR BASED ON COBALT OXIDE NANOSTRUCTURES BY ELECTROCHEMICAL METHOD Russian patent published in 2019 - IPC G01N27/12 B82Y40/00 

FIELD: technological processes.

SUBSTANCE: invention relates to the field of sensor technology and nanotechnology, in particular to the development of chemoresistive-type gas sensors used for the detection of gases. Method of manufacturing a chemoresistor based on cobalt oxide nanostructures by an electrochemical method is characterized in that in a vessel equipped with a reference electrode and an auxiliary electrode filled with electrolyte containing nitrate anions and cobalt cations, cobalt oxide nanostructures are deposited on a dielectric substrate equipped with strip electrodes acting as a working electrode by applying a constant electric potential to the working electrode from -0.5 V to -1.1 V relative to the reference electrode for 0.5–5 minutes and at an electrolyte temperature in the range of 20–80 °C, after which the substrate with the deposited layer of nanostructures of cobalt oxide is washed with distilled water and dried at room temperature.

EFFECT: invention provides the possibility of creating a chemoresistor with cobalt oxide nanostructures using an electrochemical method with a low cost in a one-step process.
