Abstract

The adsorption of acrolein and of NH3 was studied on Bi2MoO6 (model for an ammonoxidn. catalyst), together with the rate of decompn. of NH3 to N2 (first order in NH3, zeroth order in O2). Both compds. show 2 types of adsorption: (1) fast and weak, (2) slow and strong. For reduced catalysts, the strong adsorption is eliminated to give rise to a new adsorption of NH3 (acrolein then polymerizes). Data are discussed in connection with the Matsuura-Schuit model of A-and B-sites (to which they shown a good fit) and with regards to the mechanism of ammonoxidn.
