Temperature-Dependent Reactions of Phthalic Acid on Ag(100)

We have investigated the adsorption and temperature-dependent reactions of phthalic acid on Ag(100), in the temperature range 110-700 K, by synchrotron radiation X-ray photoelectron spectrocopy (SR-XPS), temperature-programmed desorption (TPD) and near-edge X-ray absorption fine structure (NEXAFS)....

The carboxylate is stable until 500 K, after which it decomposes, through desorption of CO2 and benzene, into carbon; the latter diffuses into the bulk, leaving only a little carbon on the Ag(100) surface at 600 K. © 2015 American Chemical Society.
