Decomposing water to generate hydrogen energy is one of the ideal ways to solve the future energy and environmental crisis. The reporter learned from the University of Science and Technology of China on the 4th that scientific researchers of the university have made significant progress in the study of photocatalytic total water dissolution using synchronous radiation. Prof. Wei Shiqiang and Prof. Yao Tao of the National Synchrotron Radiation Laboratory of the University of Science and Technology of China have accurately designed a catalyst by using a technique of synchrotron radiation X-rays, and made important progress in the realization of sunlight-driven spontaneous water decomposition. Related Research The results were published in the journal "German Applied Chemistry" and were selected as current hot topics. "Artificial photosynthesis", which uses sunlight to drive water decomposition, is an ideal way to achieve clean, renewable hydrogen production from solar energy, and it is also an ideal way to solve future energy and environmental crises. However, at present, most photocatalysts are difficult to achieve sunlight-driven water decomposition without sacrificing agents, and their efficiency is far from the actual application requirements. The photolysis water process involves complex multi-electron, multi-step reactions. The requirements for the catalyst materials are very high. Not only must the appropriate energy level structure absorb enough visible light, but the key is to effectively separate and transmit the photogenerated electrons. Holes, but also have highly efficient and stable hydrogen production and oxygen production active sites. Therefore, the search for a new, highly efficient, stable, and inexpensive photocatalyst still faces great challenges. Researchers used synchrotron radiation X-ray absorption spectroscopy to obtain a cobalt-based composite photocatalyst that not only greatly improved the visible light absorption of the material, but also significantly increased the lifetime of photogenerated carriers by about 20 times. They designed the photocatalyst to achieve high yields of hydrolyzed hydrogen under simulated sunlight, without sacrificing agents and precious metals. According to reports, the research will provide new design ideas and methods for further improving the water decomposition performance of existing photocatalysts.
