Example Embodiment
[0052] Example one
[0053] In the present embodiment, a method for preparing a single atomic platinum complicated electrocatalytic chloride material is mainly described by a platinum sheet electrode. The process flow is figure 1 As shown, the specific steps are as follows:
[0054] Step, formulation of chloride / ethylene glycol low-melting solvent: mixed with chloride and ethylene glycol, massaged in the beaker in a beaker, and stirred at 40 ° C for 12 h. Form a uniform colorless transparent liquid, such as figure 2 Solution A shown in;
[0055] Step 2: Preparation of the electrolyte solution: 0.2 m (2.38 g) of hexahydraminated nickel (analysis pure), 0.1M (1.19 g) of hexahydrate (analytical pure) added to a 50 ml of steps formulated. In the low-molten solvent, the temperature is stirred at 40 ° C for 2 h, resulting in a uniform ink green transparent liquid, such as figure 2 The solution B shown in the presented solution was added 0.3 g of single-layer graphene particles (GO), a...

[0062] Example 2
[0063] In the present embodiment, a method of controlling a single atomic platinum composite electrocatalytic chloride material is mainly described by a platinum sheet electrode, and the process flow is figure 1 As shown, the operation step is substantially the same as the embodiment:
[0064] Step one, with the embodiment;
[0065] Step 2: Preparation of the electrolyte solution: 0.2 m (2.38 g) of hexahydraminated nickel (analysis pure), 0.1M (1.19 g) of hexahydrate (analytical pure) added to a 50 ml of steps formulated. In the low-molten solvent, the temperature is stirred at 40 ° C for 2 h, resulting in a uniform ink green transparent liquid, such as figure 2 The solution B shown in the presented solution was added 0.2 g of single-layer graphene particles (GO), and after ultrasonic 1 h, the temperature was stirred at 40 ° C for 2 h, and finally the vacuum black liquid is figure 2 The electrolyte C shown in.
