D2 pt reaction
WebThe exchange reaction H2+D2→2HD was studied as a function of the angle of incidence (polar and azimuthal) of the beam of reactants on two stepped platinum surfaces, the Pt (S) ‐ [6 (111) × (111)] and Pt (S) ‐ [5 (111) × (111)]. The reaction probability was found to depend markedly on the direction of approach of the reactants to the step structure. WebSep 12, 2016 · The H-2/D-2 exchange reaction was studied on mono-disperse Pt-8 clusters in a mu-reactor. The chemical activity was studied at temperatures varying from room temperature to 180 degrees C using mass spectrometry. It was found that minute amounts of O-2 in the gas stream increased the chemical activity significantly.
