Fabrication and characterization of mesoporous Co3O4 core/mesoporous silica shell nanocomposites

Article Abstract:

The mesoporous Co3O4 core/mesoporous silica shell composite was fabricated by directly depositing a silica shell on a Co3O4 superlatticed aggregate, and the thickness of the mesoporous silica layer was controlled by adjusting the precocentration of tetraethoxysilane (TEOS). The most frequent pore sizes of the shell and core were ca. 2.0 and ca. 8.7 nm.

Heterogeneous activation of Oxone using Co3O4

Article Abstract:

A study is described that explores the potential of heterogeneous activation of Oxone (peroxymonosulfate) in water using cobalt oxides. Two commercially available cobalt oxides, CoO and Co3O4 were tested for the activation of peroxymonosulfate and the consequent oxidation of 2,4-dichlorophenol via a sulfate radical mechanism.
