Abstract
The adsorption and reaction of nitrogen dioxide on the Ag(1Â 1Â 1)-p(4Â ÃÂ 4)-O surface has been investigated with RAIRS, TPRS and STM. At 300Â K NO2 initially reacts with the oxygen overlayer to form nitrate in p(3Â ÃÂ 3) and p(4Â ÃÂ 4) structures, which convert to a new p(3Â ÃÂ 3) at saturation coverage. Surface pitting during nitrate adsorption is suggestive of the incorporation of silver atoms into the NO3 structure. With heating NO3 decomposes into NO2 and O at 396Â K and 497Â K, and oxygen desorbs at 578Â K.
