One‐Pot Synthesis of Superparamagnetic CoO‐MCM‐41 Nanocomposites with Uniform and Highly Dispersed Magnetic Nanoclusters

Superparamagnetic CoO‐MCM‐41 mesoporous nanocomposites, with variable cobalt amounts, in the form of well‐dispersed CoO‐like clusters, were prepared in a large compositional range by a one‐step reproducible procedure employing co‐hydrolysis and co‐condensation of the inorganic precursors in a water/triethanolamine medium.
