Embodiment 1
[0033] A kind of water-oxygen stable organic electrode, its preparation method comprises the following steps:
[0034] 1) Prepare the concentration of benzothiadiazole carbazole as 2.5×10 -4 mol / L, tetraethylammonium tetrafluoroborate concentration of 0.1mol / L electrolyte, the solvent in the electrolyte is made by mixing ultra-dry dichloromethane and ultra-dry acetonitrile according to the volume ratio of 3:2, and then glassy carbon Substrate as working electrode, platinum disk as counter electrode, Ag / Ag + The electrode is used as a reference electrode, and a cyclic voltammetry scan is performed under a nitrogen atmosphere. The potential range of the scan is -0.5V to 1.2V, the number of scan cycles is 8, and the scan speed is 100mV / s. The electrochemical polymerization curve is as figure 1 As shown, the glassy carbon substrate was rinsed with dichloromethane and acetonitrile respectively, and then placed in an oven at 120°C for 1 hour to obtain a glassy carbon substrate dep...
Embodiment 2
[0048] A kind of water-oxygen stable organic electrode, its preparation method comprises the following steps:
[0049] 1) The concentration of anthraquinone carbazole is prepared to be 2.5×10 -4 mol / L, the concentration of tetraethylammonium tetrafluoroborate is 0.1mol / L electrolyte, the solvent in the electrolyte is ultra-dry dichloromethane, then the glassy carbon substrate is used as the working electrode, the platinum disk is used as the counter electrode, Ag / Ag + The electrode is used as a reference electrode, and a cyclic voltammetry scan is performed under a nitrogen atmosphere. The potential range of the scan is -0.5V to 1.2V, the number of scan cycles is 15, and the scan speed is 100mV / s. The electrochemical polymerization of anthraquinone carbazole curve like image 3 As shown, the glassy carbon substrate was rinsed with dichloromethane and acetonitrile respectively, and then placed in an oven at 120°C for 1 hour to obtain a glassy carbon substrate deposited with ...
