Nanocrystalline K-F zeolite from rice husk silica as an eco-friendly solid base catalyst for the synthesis of jasminaldehyde under microwave irradiation

Nanocrystalline aluminosilicate F-type zeolite (K-F, EDI-type structure) was synthesized in an organic template-free system using rice husk ash (RHA) silica source and microwave energy. The morphology, crystallite size, chemical composition, crystallographic and basicity properties of the nanocrys...
