Multiple coordination of CO on molybdenum nanoparticles: Evidence for intermediate [Mo.sub.x][(CO).sub.y] species by XPS and UPS
Article Abstract:
X-ray photoelectron spectroscopy (XPS) and ultraviolet photoelectron spectroscopy (UPS) are used to investigate the Co chemisorption on the metallic molybdenum nanoparticles supported on the thin alumina film. The formation of the [Mo.sub.x][(CO).sub.y] species has implied that the property of the metallic molybdenum nanoparticles on the thin alumina film is much different from that of the bulk molybdenum, thereby implying a significant nanometer size effect.

Adsorption of bovine serum albumin on chromium and molybdenum surfaces investigated by Fourier- transform infrared reflection- absorption
Article Abstract:
The bovine serum albumin (BSA) adsorption processes on two different metals, chromium (Cr) and molybdenum (Mo) in two solutions, pure water and water with a phosphate buffer (pH7) is compared. The results suggest that the interactions between the negatively charged carboxylate groups or the positive side groups of the BSA and the passivated metal surfaces may be different on Cr and Mo.

Methane Conversion to Aromatics on Mo/H-ZSM5: Structure of Molybdenum Species in Working Catalysts
Article Abstract:
The structure and density of Mo species in Mo/H-ZSM5 during catalytic CH4 reactions is investigated by using in-situ X-ray absorption spectroscopy (XAS). Results show that CH4 reactions cause exchange in Mo(sub 2)O(sub 5)(super 2+) dimers, formed from physical mixtures of MoO3 and H-ZSM5.
