Embodiment 1

[0048] Example 1 Ni 47.5 Co 47.5 Pt 5 Amorphous nickel-cobalt alloy nano film loaded with platinum particles

[0049] The first step is to use the method of manual film making. Add 5-10mL collodion liquid to a 100mL beaker, tilt the beaker, and slowly spread the collodion liquid evenly on the bottom and side walls of the beaker. Invert the beaker for about 3 to 5 minutes. It is air-dried naturally, and the film is peeled off for use.

[0050] The second step is to accurately weigh out 5.65mg of NiCl 2 ·6H 2 O, 5.65mg of CoCl 2 ·6H 2 O and 1.30mg of H 2 PtCl 6 ·6H 2 Put O in a beaker, add 10ml of deionized water, stir well to dissolve it, and configure it as Ni 47.5 Co 47.5 Pt 5 Aqueous solution.

[0051] The third step is to accurately weigh 26.97mg of KBH 4 Place it in a beaker, add 10ml deionized water, stir well to dissolve it, and configure it to 0.05mol / L KBH 4 Solution, add 3 to 5 drops of 0.2mol / L NaOH solution to adjust its PH value to 10-12.

[0052] The fourth step is to add...

Embodiment 2

[0054] Example 2 Ni 40 Co 40 Pt 20 Amorphous nickel-cobalt alloy nano film loaded with platinum particles

[0055] The first step is to use the method of manual film making. Add 5-10mL collodion liquid to a 100mL beaker, tilt the beaker, and slowly spread the collodion liquid evenly on the bottom and side walls of the beaker. Invert the beaker for about 3 to 5 minutes. It is air-dried naturally, and the film is peeled off for use.

[0056] The second step, accurately weigh 4.75mg NiCl 2 ·6H 2 O, 4.75mg CoCl 2 ·6H 2 O and 5.18mg H 2 PtCl 6 ·6H 2 Put O in a beaker, add 10ml of deionized water, stir well to dissolve it, and configure it as Ni 40 Co 40 Pt 20 Aqueous solution.

[0057] The third step is to accurately weigh 26.97mg of KBH 4 Place in a beaker, add 10ml of deionized water, stir well to dissolve, configure to 0.05mol / L KBH 4 Solution, add 3 to 5 drops of 0.2mol / L NaOH solution to adjust its PH value to 10-12.

[0060] Example 3 Ni 25 Co 25 Pt 50 Amorphous nickel-cobalt alloy nano film loaded with platinum particles

[0061] The first step is to use the method of manual film making. Add 5-10mL collodion liquid to a 100mL beaker, tilt the beaker, and slowly spread the collodion liquid evenly on the bottom and side walls of the beaker. Invert the beaker for about 3 to 5 minutes. It is air-dried naturally, and the film is peeled off for use.

[0062] The second step is to accurately weigh 2.97mg NiCl 2 ·6H 2 O, 2.97mg CoCl 2 ·6H 2 O and 12.95mg H 2 PtCl 6 Place it in a beaker, add 10ml deionized water, stir well to dissolve it, and configure it as Ni 25 Co 25 Pt 50 Aqueous solution.

[0063] The third step, accurately weigh 26.97mg KBH 4 Place in a beaker, add 10ml of deionized water, stir well to dissolve, configure to 0.05mol / L KBH 4 Solution, add a certain 0.2mol / L NaOH solution to adjust its PH value to 10-12.

Abstract

The invention relates to a method for synthesizing an amorphous nickel-cobalt alloy nano-film loaded with platinum particles, which comprises the following steps: taking an artificial active pyroxylin membrane as a template; reducing a metal salt by a composite hydrogen compound at the normal temperature; and then obtaining the amorphous nickel-cobalt alloy nano-film loaded with the platinum particles. The method has very high regulation to an alloy component content of a product; a simple inorganic salt is adopted as a reactant respectively with very strong universality; the product prepared by the method has good electrochemical property, can be used as a high performance electrochemical catalyst and has wide development prospect and application space; and the method has the advantages of simple process, mild preparation conditions, stable appearance and high purity of the product, convenient and concise treatment of the product, and suitability for middle-scale industrial production.

Description

Technical field [0001] The invention belongs to the technical field of materials, and specifically relates to a method for synthesizing an amorphous nickel-cobalt alloy nano film loaded with platinum particles from an artificial active template. Background technique [0002] Nano science and technology is a new technology that was developed rapidly in the late 1980s. The so-called nanotechnology refers to the use of a number of molecules or atoms composed of units-nano particles, the science and technology of manufacturing materials or micro devices. Nanoparticles refer to fine particles of metal or semiconductor with a size between 1 and 100 nm. The special structure level of nano particles gives it many special properties and functions, such as surface effect, small size effect, quantum size effect, macro quantum tunneling effect, dielectric confinement effect, etc. This series of novel physical chemistry The characteristics make it have great application value in many fields...
