Surface-analytical studies of supported vanadium oxide monolayer catalysts
Article Abstract:
The X-ray photoelectron spectroscopy (XPS) and ion scattering spectroscopy (IEE) are used to investigate the in situ calcinations and dehydration of supported vanadia catalysts. The XPS and ion scattering spectroscopy (ISS) surface studies confirms that the supported vanadium oxide catalysts consists of close-packed monolayers of surface vanadia species.

In situ spectroscopic investigation of molecular structures of highly dispersed vanadium oxide on silica under various conditions
Article Abstract:
Research was conducted to examine the molecular structures of highly dispersed vanadium oxide on silica under different conditions. In situ spectroscopic methods such as Raman and Fourier transform infrared spectroscopy, XPS, 51V NMR, solid-state, UV-vis DRS and the V K-edge EXAFS/XANES were used. Results indicate that in the dehydrated state, only isolated VO4 species were present on the silica surface up to monolayer coverage.
