Embodiment 1

[0040] figure 1 and figure 2 As shown in the figure, it is a state diagram of the synthesis and preparation of the hydrogen production catalyst for electrolysis of water.

[0041] Quantities of the chemical substances used in the preparation are determined according to a preset range, with grams and milliliters as measurement units.

[0042] The synthesis of electrolyzed water hydrogen production catalyst is carried out in agate grinding and tube furnace, which is completed by room temperature grinding process and high temperature calcination under inert atmosphere;

[0043] figure 1 As shown, the reaction precursors (cobalt chloride, thiourea and glucose) were added to the agate mortar and manually ground for 30 min.

[0044] figure 2 As shown, the high-temperature calcination is carried out in a tube, using nitrogen as a protective gas, and the calcination temperature is 800-1000°C. figure 2 The medium carbonization device includes: air inlet 1, vacuum port 2, flange...

Abstract

The invention relates to the technical field of preparation and application of catalyst materials, in particular to a preparation method of an electrolyzed water hydrogen production catalyst. The preparation method adopts a molten salt synthesis method, cobalt chloride is used as a template and a cobalt source, thiourea is used as a nitrogen source and a sulfur source, glucose is used as a carbonsource, under the condition of a room temperature, manual grinding is performed for 30 min in an agate grinding bowl, obtained blue powder is used for preparing the electrolyzed water hydrogen production catalyst by high temperature calcination in a tube furnace, and the pore passage structure and heteroatom content of the material can be adjusted by controlling the calcination temperature. The preparation method is high in product yield of 41%, the material can be used as the electrolyzed water hydrogen production catalyst, and the preparation method is an ideal method for preparing the electrolyzed water production catalyst.

Description

technical field [0001] The invention relates to the technical field of preparation and application of catalyst materials, in particular to a preparation method of a hydrogen production catalyst for electrolysis of water. Background technique [0002] Nowadays, science and technology not only promote the progress of society and bring a lot of convenience to our life, but also bring some adverse effects. For example, the continuous consumption of non-renewable energy such as fossil energy has caused human beings to suffer from an energy crisis. At the same time, its combustion product CO 2 , SO 2 The greenhouse effect and air pollution caused by the discharge of these gases into the air are gradually eroding human homes. [0003] In order to meet the world's increasing energy demand, more sustainable energy sources need to be discovered to replace the current fossil fuels. As a clean, non-polluting, high-calorific and widely distributed energy source in the world, hydrogen ...
