The pulse radiolysis of nitrobenzene (NB) in aqueous solutions containing 2-propanol in the presence of colloidal Pt has been studied. The NB/sup -/ anion decays away by a single first-order process. The rate of decay is also first order in colloidal platinum (Ptc). The rate depends on the pH of the solutions. At relatively high pHs, hydrogen reduces NB and this reaction is mediated by the Ptc. Irreversible redox processes which produce nitrosobenzene and phenylhydroxylamine also take place, competing effectively with hydrogen formation. 21 references, 6 figures, 4 tables.
