Реферат:
The influence of NO on the adsorption of D2 on the Pt(100)–(hex) surface was studied by means of temperature-programmed reaction (TPR). Deuterium adsorbs negligibly on Pt(100)–(hex) at T=270 K, whereas an addition of a small amount of NO to D2 increases drastically the adsorption capacity of Pt(100)–(hex) towards deuterium. The same phenomenon was observed on the surface pre-covered with NOads as well. As the NOads pre-coverage increases, the uptake of Dads first increases, then reaches a maximum at θNO≈0.25 ML, and finally falls down to zero for the NOads saturated layer.
The following explanation is supposed. Upon adsorption on the Pt(100)–(hex) surface, NO lifts the (hex) reconstruction and forms the dense NOads/(1×1) islands surrounded by the clean (hex) surface. A limited area of the (hex) phase, which is immediately adjacent to the boundaries of the NOads/(1×1) islands, is supposed to be distorted and could be able to adsorb deuterium.
