The reactivity of oxidized ZrC(100) surfaces toward H 2 O and CH 3 OH adsorption has been investigated using X-ray photoelectron spectroscopy and ultraviolet photoelectron spectroscopy. It is found that the reactivity of the ZrC(100) surface toward H 2 O adsorption is much enhanced when the surface is covered with an ordered suboxide (ZrO) like layer; H 2 O does not...
Ultraviolet photoelectron spectroscopy (UPS) has been used to study methanol adsorption on ZrC(100) and (111) surfaces. It is found that methanol adsorbs molecularly on the ZrC(100) surface at room temperature. On the other hand, UPS study shows that methanol is dissociated on the ZrC(111) surface; methoxy species and completely dissociated atomic species (C, H and O atoms) are coexistent on the ZrC(111)...
