Abstract Details

Hexagonal boron nitride (hBN) is a material recently discovered to exhibit surprising catalytic activity for the oxidative dehydrogenation of hydrocarbons. Previous studies indicate that redox sites can be produced on hBN, which suggests that hBN may also have potential in other oxidation reactions. In this work, hBN is instead tested as a catalyst and catalytic support for the oxidation of methanol over a temperature range of 210-360 °C. Methanol oxidation additionally reveals changes in surface active sites due to the formation of characteristic products for acid, basic, and redox active sites. Thermal treatment and sonication of hBN are demonstrated to have significant effects on conversion and product selectivity during methanol oxidation reactions. Dispersion of vanadium oxide on hBN yields increased redox activity and methanol conversion due to formation of VOx groups on the surface of hBN. The supported vanadium catalyst is shown to have superior performance when hBN is also exposed to thermal treatment and sonication. Raman, XRD, and FTIR studies are performed to characterize changes in the catalyst due to treatment or vanadium dispersion. Experiments are also performed to measure changes in active sites due to in situ functionalization of hBN during propane oxidation.
