摘要：

Fresh gold surfaces were formed by scratching under high vacuum conditions, and adsorption and reactions of organic compounds on the surface were monitored with a quadrupole mass spectrometer. It was found that the gold surface was activated tribochemically by scratching, and various organic compounds chemisorbed on the fresh surface. The estimated chemisorption activities were closely related to the functional group of the organic compounds. Hydrogen evolution due to decomposition of adsorbed molecules was observed even after the termination of scratching. Hydrocarbons were also evolved on adsorption of organic iodide. It is concluded that gold surface becomes so active by scratching that chemisorption and decomposition of organic compounds occur on it even at room temperature.
