Preparation of hollow layered MoO3 microspheres through a resin template approach

Hollow layered MoO3 microspheres were obtained by the adsorption of 12-molybdodiphosphate onto the surface of a spherical anion exchange resin followed by calcination of the resulting 12-molybdodiphosphate-resin composite. The conductivity of the sphere shell can be improved by intercalating polyaniline between layers of MoO3 particles in the sphere shell.
