Embodiment 1

[0030] Cobalt sulfide materials are prepared by the following steps:

[0031] (1) Sodium dimethyldithiocarbamate and cobalt chloride hexahydrate were mixed in a 500ml beaker at a molar ratio of 2:1, 200ml to 400ml of water was added, stirred at room temperature for 10min to 30min, and a solid sample was obtained by suction filtration. Dry the sample in an oven at 100°C for 8h to 12h;

[0032] (2) 1 g of the product obtained in step (1) is placed in a tube furnace, and under the protection of argon, the temperature rises from room temperature to 500 °C at a rate of 5 °C / min, and is kept at this temperature for 2 hours. After cooling to room temperature, the sample was taken out to obtain a cobalt sulfide material.

Embodiment 2

[0034] The preparation method of cobalt sulfide material refers to Example 1, the difference is that in step (2), the product is raised from room temperature to 600° C. in a tube furnace at a heating rate of 5° C. / min.

Embodiment 3

[0036] The preparation method of cobalt sulfide material refers to Example 1, the difference is that in step (2), the product is raised from room temperature to 800° C. in a tube furnace at a heating rate of 5° C. / min.

Abstract

The invention provides a cobalt sulfide material, a preparation method and application of the cobalt sulfide material. The cobalt sulfide material is prepared by the following steps: (1) mixing dimethyl aminodithioformic acid with cobalt chloride hexahydrate according to a mole ratio of 2 to 1 in water for reaction, thus obtaining a first product; (2) under the protection of inert gas, carrying out reaction on the dried first product at 500 to 900 DEG C for 2 to 3 hours, thus obtaining the cobalt sulfide material. The cobalt sulfide material provided by the invention can be applied to the field of hydrogen production from water through electro-catalysis.
