Molybdenum platinum porous composite material as well as preparation method and application thereof

Abstract

The invention provides a molybdenum platinum porous composite material as well as a preparation method and application thereof. The preparation method comprises the following steps that a carbon nanotube is added into a solvent; turbid liquid is formed through ultrasound, and is then dripped on the surface of a pretreated glassy carbon electrode; a carbon nanotube thin layer is formed; a glassy carbon electrode is obtained; the glassy carbon electrode modified by the carbon nanotube is put into electroplating liquid to implement the electroplating; cleaning and natural drying are performed; then, the glassy carbon electrode containing a molybdenum sulfide carbon nanotube composite material is put into a sulfuric acid solution; pt is used as a counter electrode; a saturated calomel electrode is used as a reference electrode; under the certain condition, the glassy carbon electrode coated with a molybdenum platinum/carbon nanotube composite material is obtained; the glassy carbon electrode is cleaned by water and is naturally dried at normal temperature; the composite material is scrapped from the surface of the glassy carbon electrode to obtain a final product. The operation of themethod is simple; the prepared composite material has great advantages in the aspects of electrocatalysis hydrogen production, electrocatalysis oxygen evolution, electrocatalysis oxygen reduction andenergy conversion; the composite material can be applied to the fields of fuel battery and new energy source conversion.

Description

technical field [0001] The invention belongs to the research field of nanocomposite materials, and in particular relates to the preparation of nanocomposite materials by sweeping CV of pt counter electrodes and using them as electrocatalysts for research. Background technique [0002] For a long time, humans have been using fossil fuels such as oil as the main energy source, and the consequence of doing so is that we are facing more and more serious energy crises, air pollution, and global warming. At present, in order to solve these problems, we urgently need to find a clean and renewable energy to replace traditional fossil fuels. The combustion product of hydrogen is water, which is non-polluting and can alleviate air pollution. Therefore, hydrogen has become one of the alternative energy sources favored by many researchers. However, hydrogen in nature mainly exists in the form of gas, and its content is relatively small. It is far from meeting the daily needs of human b...

Problems solved by technology

However, the problem we must realize is that the technology we have at this stage for electrolyzing water to produce hydrogen is still not mature enough, and the cost required in the preparation process is still too high, and the key to the problem lies in the catalyst for electrolyzing water to produce hydrogen. Some non-precious metal catalysts reported in 2010 have general performance, poor stability and short life, which is not conducive to wide application.
