▎ 摘  要

NOVELTY - Method comprises preparing two-dimensional carbon material with high dispersity, adding excessive sodium borohydride or glucose or hydrazine hydrate as reducing agent into the two-dimensional carbon material; stirring and preparing carbon-based alcohol electroactive catalyst loaded with platinum-based nanoparticles at room temperature; mixing the carbon-based alcohol electroactive catalyst loaded with platinum-based nanoparticles with deionized water and perfluorosulfonic acid, preparing into alcohol electroactive catalyst slurry; manufacturing a screen printing three-electrode sensor array with pre-set working electrode area; screen printing the silk screen printing conductive paste on the flexible substrate to manufacture the sensor array; modifying the working electrode surface of the alcohol electroactive catalyst slurry in the three-electrode system of the screen printing; modifying perfluorosulfonic acid; connecting three-electrode sensing array with the circuit. USE - The method is useful for preparing wearable intelligent high-selectivity gas-liquid double-functional alcohol electrochemical sensor. ADVANTAGE - The sensor exhibits very strong substrate applicability and environment applicability; exhibits considerable sensing stability under a certain stretching and bending state; can be connected with the circuit; and through the Bluetooth device, real time measuring and reading the concentration of the object to be tested on the mobile phone. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for wearable intelligent high-selectivity gas-liquiddouble-functional alcohol electrochemical sensor preparation method
