Novel macroporous vanadium-phosphorus-oxides with three-dimensional arrays of spherical voids

摘要

Macroporous vanadium phosphorus oxide phases with unique compositional, structural and morphological properties have been synthesized by employing close-packed hexagonal arrays of polystyrene spheres as a template. The macroscale-templated synthesis produced VPO phases with unprecedented high surface areas, desirable macroporous architecture, as well as optimal bulk composition and preferential exposure of the surface (100) planes of the catalytically active and selective phase VO_2P_2O_7 for the partial oxidation of n-butane.
