文摘Adsorption of deuterated methanol(CH_(3) OD)on Si(111)surface has been studied at different temperatures by means of thermal desorption spectroscopy.For the adsorption temperature below 420℃,the desorption peak of hydrogen kept up almost unchanged at 510℃(±70℃).But the desorption peak temperature of hydrogen increased obviously for the adsorption temperature above 420℃.We have also found an interesting change in desorption energy of hydrogen.
