Embodiment 1
[0060] Oxygen-assisted deposition of ZIF-8 on HOPG includes the following steps:
[0061] (1) Preparation containing 10mM ZnCl 2 , 20mM HmiM and 100mM (NBu 4 )PF 6 Methanol solution, pass high-purity air for 30min before deposition;
[0062] (2) It is obtained by electrochemical deposition on the surface of the cathode conductive substrate by using the constant voltage method (three-electrode system). Among them, the working electrode is HOPG, the counter electrode is Pt wire, and the reference electrode is Ag / AgCl electrode. -0.5V, 2h; -0.7V, 2h; 6h, 12h; -0.9V, 2h; -1V, 2h.
[0063] HOPG treatment: Graphite needs to be exposed immediately after use to prevent surface contamination or fracture, which will affect conductivity and crystal growth. When necessary, use high-temperature-resistant double-sided adhesive to stick to the graphite surface, gently rub and press, and finally peel off the layer before use. To ensure the continuity of the graphite sheet, no hydrophilic...

[0069] Oxygen-assisted deposition of ZIF-8 on ITO includes the following steps:
[0070] (1) Preparation containing 10mM ZnCl 2 , 20mM HmiM and 100mM (NBu 4 )PF 6 methanol solution;
[0071] (2) It is obtained by electrochemical deposition on the surface of the cathode conductive substrate by cyclic voltammetry (three-electrode system), wherein the working electrode is ITO, the counter electrode is Pt wire, the reference electrode is Ag / AgCl electrode, and the voltage range -0.8V~0V, scan rate 100mV / s, deposition time respectively 10 min, 15 min, 30 min, 60 min, 120 min, 240 min.
[0072] ITO processing: 100*10 mm 2 The ITO were placed in acetone. Sonicate in ethanol and deionized water for 15 minutes, rinse with deionized water, N 2 Blow dry and place in 1:1:5 H 2 o 2 , NH 3 h 2 O:, H 2 In the mixed solution of O, after heating at 90°C for 2 hours, rinse with deionized water, N 2 blow dry.
[0073] The processing method of Pt and Ag / AgCl electrode is the same as...
Embodiment 3
[0076] Oxygen-assisted deposition of ZIF-8 on carbon fibers includes the following steps:
[0077] (1) Prepared with 10 mM ZnCl 2 , 20 mM HmiM and 100 mM (NBu 4 )PF 6 Methanol solution, pass high-purity air for 30min before deposition;
[0078] (2) It is obtained by electrochemical deposition on the surface of the cathode conductive substrate by constant voltage method (three-electrode system), wherein the working electrode is carbon fiber, the counter electrode is Pt wire, the reference electrode is Ag / AgCl electrode, and -0.9 The voltage of V was deposited for 1 h.
[0079] Carbon fiber treatment: Soak the carbon fiber in H with a volume ratio of 3:7 2 o 2 and concentrated H 2 SO 4 heat treatment at 70°C for 1 h, then rinse repeatedly with deionized water for several times, and finally soak in clean deionized water for later use, take it out and dry it in an oven at 80°C before use, and cool to room temperature. be usable.
[0080] The processing method of Pt and A...
