Description
Technical Field

Background
The existing traditional energy sources such as petroleum, natural gas, coal and petroleum gas belong to non-renewable resources, the stock on the earth is limited, and the human beings can not leave the energy sources all the time for survival, so new energy sources must be searched. With the increasing consumption and decreasing reserves of fossil fuels, the resources and energy sources will be exhausted in the whole day, and a new energy-containing body energy source which is rich in reserves and does not depend on the fossil fuels is urgently needed to be found. Hydrogen is just such a new secondary energy source that people expect while the conventional energy crisis appears and new secondary energy sources are developed. Hydrogen is at the head of the periodic table of elements, has an atomic number of 1, and is in a gaseous state at normal temperature and normal pressure and in a liquid state at ultralow temperature and high pressure. Hydrogen energy is a recognized clean energy source that is emerging as a low and zero carbon energy source. In the 21 st century, hydrogen energy development plans are made in China, the United states, Japan, Canada, European Union and the like, and at present, China has made various progress in the field of hydrogen energy, is expected to become one of the leading countries of hydrogen energy technology and application in the near future, and is also considered by international public as the country which is most likely to take the lead to the realization of industrialization of hydrogen fuel cells and hydrogen energy automobiles.
Hydrogen is generally produced industrially by the following methods: firstly, the steam is passed through a glowing coke (called a carbon reduction method) to obtain hydrogen with the purity of about 75 percent; secondly, the water vapor passes through the hot iron to obtain hydrogen with the purity of below 97 percent; thirdly, hydrogen is extracted from the water gas, and the purity of the obtained hydrogen is lower; the fourth method is an electrolytic water method, and the purity of the prepared hydrogen can reach more than 99 percent, which is an important method for preparing hydrogen industrially. However, in order to improve the efficiency of hydrogen production by water electrolysis, an effective catalyst is used. However, the existing electrode material has low conversion rate and long conversion time in the hydrogen production process, and influences the rapid and efficient preparation of hydrogen.
