Nobel Prize in Chemistry: The Nobel Prize Committee of the Royal Swedish Academy of Sciences announced today that the 2007 Nobel Prize in Chemistry will be awarded to the German scientist Gerhard ?6?1 Ertel in recognition of his "solid surface" For his contribution to the research of "Chemical Processes", he will receive a prize of 10 million Swedish krona (approximately US$1.54 million). The Nobel Prize Committee stated in the award announcement that the Nobel Prize in Chemistry was awarded to Gerhard 6.1 Ettel for his pioneering research in surface chemistry. Surface chemistry is important to the chemical industry, helping us understand different processes such as why iron rusts, how fuel cells work, how catalysts in cars work, etc. Furthermore, surface chemical reactions play an important role in many industrial processes, such as the production of artificial fertilizers. Surface chemistry can even explain the destruction of the odor layer, and the semiconductor industry is also an area related to surface chemistry. Modern surface chemistry began to appear in the 1960s due to the development of the semiconductor industry. Gerhard Ertl was one of the first scientists to discover the potential of new technologies. He gradually established research methods on surface chemistry and showed people the full picture of surface reactions produced by different experimental processes. This science requires advanced vacuum experimental equipment to observe how metals work at the atomic and molecular level and determine what materials are put into the system. Gerhard Ertel's observations provided the scientific basis for modern surface chemistry, and his methods are used not only in academic research but also in chemical industry research and development. The research method invented by Gerhard 6?1 Eitel is based on his research on the Haber-Bosch method. The Haber-Bosch method can extract nitrogen from the air, which is of great economic significance. Eitel also studies the oxidation of carbon monoxide over platinum catalysts, a chemical reaction that occurs primarily in automotive catalysts to filter exhaust gases produced by cars. Gerhard 6?1 Eitel was born in Bad Canstatt, Germany in 1936. He received his PhD in chemistry from the Technical University of Munich in 1965 and is an honorary professor at the Fritz Haber Institute of the Max Planck Society in Berlin. .
