Single-Step Formation of Metal Oxide Nanostructures Wrapped in Mesoporous Silica and Silica-Niobia Catalysts for the Condensation of Furfural with Acetone.

ABSTRACT: The integration of metal oxide nanomaterials with mesoporous silica is a promising approach to exploiting the advantages of both types of materials. Traditional synthesis methods typically require multiple steps. This work instead presents a fast, one-step, template-free method for the synthesis of metal oxides homogeneously dispersed within mesoporous silica, including oxides of W, Ti, Nb, Ta, Sn, and Mo. These composites have tunable metal oxide contents, large surface areas, and wide mesopores. The combination of Nb₂O₅ nanoparticles (NPs) with SiO₂ results in an increased surface area and a larger number of acid sites compared to pure Nb₂O₅ NPs. The surface texture and acidity of the silica-niobia composites can be tuned by adjustin
