This paper reports the preparation of Pt / PolyCuTAPc / Nafion modified Pt microelectrode by electrochemical polymerization and the use of the modified electrode to make the gas oxygen sensor. The electrochemical behavior of the sensor is also studied and applied to the determination of oxygen and oxygen. The experiment found that the sensor has a good catalytic reduction effect on oxygen, has high sensitivity, selectivity and good anti-pollution ability for oxygen determination, the response time is less than 5s, the parallel determination of 7 times oxygen concentration, the relative standard The deviation is 0.36%.
