A General Synthesis Strategy for Hierarchical Porous Metal Oxide Hollow Spheres

A General Synthesis Strategy for Hierarchical Porous Metal Oxide Hollow Spheres

The hierarchical porous TiO2 hollow spheres were successfully prepared by using the hydrothermally synthesized colloidal carbon spheres as templates and tetrabutyl titanate as inorganic precursors. The diameter and wall thickness of hollow TiO2 spheres were determined by the hard templates and conce...
