Abstract
The NO-H, reaction over Pd(111) was studied at NO pressures in the 1 x 10(- 7) mbar pressure regime and at temperatures between 300 and 750 K. The H-2/ NO ratio was varied from 1 to 54. Hysteresis phenomena in the rate of NH3 a nd H2O formation were observed in a heating-cooling cycle and call be attri buted to atomic hydrogen absorbed in the bulk. (C) 2000 Elsevier Science B. V.
