Nanostructured Vanadia‐Titania Catalysts with Hierarchical Architecture in the Oxyhydrative Scission of 1‐Butene to Acetic Acid

Abstract

The synthesis of hierarchically designed supported vanadia‐titania catalysts and their properties in the oxyhydrative scission (OHS) of 1‐butene to acetic acid (AA) is described. The interaction of the TiO2 support with V2O5 appears to be responsible for an enhanced catalytic performance, and it is proposed that the catalytic activity is related to the number and size of the contact zones between the support and the active component.

V2O5 Nanorods on TiO2 Nanofibers: A New Class of Hierarchical Nanostructures Enabled by Electrospinning and Calcination

“…To achieve optimal performances, hierarchical structures with controlled crystalline structures and spatial distribution of each component are often desired. 13 Electrospinning allows convenient fabrication of hierarchically structured oxide materials with high porosity, surface area, as well as controlled compositions and sizes. In particular, electrospun nanofibers are small in diameter but long in length, which makes it very convenient to study both their microstructure (as shown in this work) and their macroscopic properties.…”
