Multi-duct transition metal phosphide carbon nanotube composite material and preparation method and application based on small molecule regulation

Abstract

The invention provides a multi-duct transition metal phosphide carbon nanotube composite material and a preparation method and application based on small molecule regulation. A mixture of carbon nanotubes and small molecules is added into a solvent, ultrasound treatment is carried out to form turbid liquid to be dropwise added into a pretreated glassy carbon electrode surface, natural drying is carried out to form even carbon nanotube thin layers, and a glassy carbon electrode modified with the mixture of the carbon nanotubes and the small molecules is obtained; phosphate and transition metalsalt are added into deionized water, electrolyte is supported, sulfuric acid is used for adjusting pH to be 0-13, and electroplate liquid is obtained; and the glassy carbon electrode modified with themixture of the carbon nanotubes and the small molecules is placed into the electroplate liquid to be electroplated, washing with water is carried out, natural drying is carried out at the normal temperature, and a blade is used for scrapping a prepared composite material from the surface of the glassy carbon electrode, and the final product is obtained. The method is easy to operate, the preparedcomposite material has the great advantages in the aspects of catalytic hydrolysis separation and energy conversion, and the product and the preparation method can be applied to the field of electro-catalysis water decomposition hydrogen production and photovoltaic conversion.

Description

technical field [0001] The invention belongs to the research field of nanocomposite materials, and in particular relates to a transition metal phosphide carbon nanotube composite material passing through porous channels, its preparation method and application based on small molecule regulation, and its application research as an electrocatalyst. Background technique [0002] Traditional fossil energy, as a non-renewable energy, is facing a major crisis of resource depletion, and the use of fossil energy has brought a series of environmental problems. Therefore, in order to achieve sustainable development, maintain and create a healthy ecological environment, many countries in the world have begun to devote themselves to the development and utilization of new energy, such as solar energy, nuclear energy, wind energy, hydrogen energy, etc. Among them, hydrogen energy may become the most ideal energy source. The reason is that in the case of burning the same weight of coal and...

Problems solved by technology

At present, platinum or platinum alloys are commonly used cathode catalysts for electrolyzing water to produce hydrogen. However, platinum resources are relatively scarce in nature and are expensive, resulting in high costs for electrolyzing water to produce hydrogen, which limits its large-scale use in industrial production.
