Microporous Organic Network Hollow Spheres: Useful Templates for Nanoparticulate Co3O4 Hollow Oxidation Catalysts

Hollow microporous organic networks (H-MONs) were prepared by a template method using silica spheres. The shell thickness was delicately controlled by changing the synthetic conditions. The H-MONs were used as a template for the synthesis of nanoparticulate Co3O4 hollows which showed excellent catalytic performance in H2O2 oxidation.
