Abstract
Introduction
Catalysts consisting of oxidic vanadium species supported on SBA-15 (VOx/SBA-15) exhibit excellent performance in several reactions such as oxidative dehydrogenation of propane [1] and oxidation of methane [2] or methanol [3] for production of formaldehyde. The potential of SBA-15 for catalytic applications arises from the uniformly sized hexagonally ordered pores, high hydrothermal stability and large surface area, which allows for highly dispersed vanadium species in the channels of the SBA-framework. Little is reported on the nature of vanadium in such materials; and the goal of this work is to investigate the state and redox properties of vanadium supported on SBA-15. The vanadium sites were characterized by CO adsorption after different sample pretreatments, and the adsorbate complexes were studied by FTIR spectroscopy.
