摘要：

Only a small portion of hydrogen-metal interactions are covered in this review. The emphasis is on peculiar changes in chemisorptive and catalytic properties of metal catalysts brought about by their exposure to hydrogen above 670 to 770/sup 0/K. Electron loss spectroscopy or work function measurements can be used for the investigation of hydrogen on metals. Most useful are techniques where the effects of hydrogen manifest themselves indirectly, as in temperature-programmed desorption, radiotracer studies, electron microscopy, or x-ray diffraction along with chemisorption and hydrogen/oxygen titation. Combined techniques, NMR, magnetic measurements, electrochemistry, are also available. A review of these aspects is presented. The next section summarizes hydrogen effects on catalytic activity and selectivity in hydrogenation/dehydrogenation, skeletal rearrangments. A brief survey of technological implications is included. 203 references, 29 figures, 22 tables.
