Title
Greener oxidation of aldehydes over bio-silica supported Fe2O3 nanoparticles: A convenient ‘NOSE’ approach
Abstract

•A recyclable and robust Fe2O3NPs@DE catalyzed oxidation of aldehydes at room temperature has been developed.•DE acts as a smart support for Fe2O3NPs and enhances its oxidative catalytic action.•The novel supported catalyst is air stable.•The measurement of “green-ness” makes it a benign alternative over others.

A recyclable, robust and highly active Fe2O3 nanoparticles supported over bio-silica, i.e. diatomaceous earth (Fe2O3NPs@DE) catalyzed oxidation of aryl/alkyl/heteroaryl aldehydes at room temperature has been developed. The DE enhanced the catalytic activity of Fe2O3 NPs dramatically by serving itself as a smart support. Fe2O3NPs@DE could be efficiently reused with a slight loss in its catalytic activity. The novel supported catalyst is air stable and hence all the reactions can be conducted under aerobic condition. By the measurement of the “green-ness” our protocol emerges as a benign alternative over the existing methodologies.
