“I believe that one day, water can be used as fuel. The hydrogen and oxygen that make up the water can be used alone or together. This will provide an unlimited source of heat and light. The intensity of the light and heat supplied is beyond the reach of coal. Yes, water will be the coal of the future.†In 1870, Gilles Fein wrote this seemingly “nightmare†prophecy in the science fiction “The Isle of Mystery,†but he never managed to wait until the day of his dream come true. . One hundred years later, this scientific research by European and American scholars and breakthroughs by Japanese scholars took the lead in leaping out of the laboratories with the efforts of Chinese scholars to become “ultimate†new energy that could be used commercially. On January 9th, Professor Zou Zhigang of Nanjing University and Professor Yu Jiaguo of Wuhan University of Technology held a certificate in the Great Hall of the People in Beijing with both hands. In this National Science and Technology Award Conference, the field of photocatalytic materials won two second prizes in natural science in one fell swoop. Surprisingly, they actually came from the same 973 project team. Among them, Zou Zhigang and others completed the "visible light response photocatalytic materials and basic research in the application of energy and the environment," is the use of solar visible light to decompose water into hydrogen and oxygen, the conversion efficiency of up to 6%, as the international leader. "Hydrogen has the name of green fuel. It is taken from water and returned to water after combustion. Its fuel value is three times that of gasoline. Both rockets and high-speed cars use hydrogen as the best fuel for boosting power." Zou Zhigang talks about it. Hydrogen energy is very excited. "Hydrogen is the ultimate energy source for human beings. This is a dream-like technology!" However, the simplest way to obtain hydrogen at present is electrolysis, which uses electricity to decompose water into hydrogen and oxygen, neither environmentally friendly nor energy-efficient. How to get hydrogen in a clean way has become a dream for scientists around the world. In 1972, two scientists at the University of Tokyo in Japan discovered that under UV light, titanium dioxide single crystal electrodes can cause water to decompose under normal temperature and pressure, producing hydrogen and oxygen. At that time, when the oil crisis in the Middle East broke out, this discovery undoubtedly injected a "strengthening agent" for those who were caught in the panic of the energy crisis. Since then, "photodecomposition of water to make hydrogen" has not only become a hot spot in scientific research, but has also deeply embedded the dream plan for new energy of all mankind. Over the past 30 years, despite the unremitting efforts and efforts made by scientists from all over the world, only 5% of the ultraviolet light in the sunlight has caused the conversion rate of photodecomposition and hydrogen production to be very low. If you want to further improve the conversion efficiency and have practical commercial value, you can only break in the direction of visible light. In 2001, Zou Zhigang and his collaborators wrote a big exclamation mark in this field: they applied crystalline physics material design techniques, experience and knowledge obtained in the field of oxide superconducting materials to the field of photocatalysis for the first time in the world. We successfully developed a visible light-responsive water full-decomposition photocatalyst and published it in the journal Nature. On the same day, the world’s other famous scientific journal, Science, was also titled “Water + Sun + New Catalysis = New Energyâ€. Distributing comments, saying "this is a breakthrough, although there is still a lot of work to be done, but this research result will certainly affect the entire process of future research." So far, in Finn's science fiction, what people call "dream-like technology" began to shine into reality. Photocatalytic technology not only has huge application prospects in the energy field, but also has great potential for environmental protection. At present, this technology has been successfully applied in wastewater treatment and air purification in many places in China under the leadership of Academician Fu Xianzhi of Fuzhou University. They are also members of the same 973 team. With the support of the 973 project, China’s photocatalytic technology has made considerable progress and the outlook is even more probable: The team took the lead in carrying out research on photosynthesis of artificial plants in the world. They used water and carbon dioxide as raw materials to successfully convert carbon dioxide into carbon. Hydrogen fuels - methane, etc. Not only did it create a clean carbon cycle, it also attracted follow-up research from foreign counterparts. In addition, the team is also the first in the world to conduct photocatalytic decomposition of seawater. They use unlimited sunlight and endless seawater to produce hydrogen energy, which in turn produces fresh water. This will also be a major solution to the global freshwater crisis. Gospel. The National Natural Science Second Prize has given this 973 project team greater impetus, and it also promoted the development of new research directions based on the original research of photocatalytic technology. "It is expected that by the end of the second phase of the 973 project, our photocatalytic hydrogen production conversion rate will reach 8%, which is close to the 10% commercialization target set by the US Department of Energy. The Chinese people are expected to take the lead in realizing human dreams of a century ago. "Zou Zhigang said," But what happens after the hydrogen energy is produced? To this end, we will also apply the development of technologies such as fuel cells in the next step, and ultimately achieve low-cost, high-efficiency and environmentally-friendly generation and utilization of hydrogen energy."
