Copper-incorporated fluorapatite encapsulated iron oxide nanocatalyst for synthesis of benzimidazoles

Abstract

Abstract: γ-Fe2O3@CuFAp nanocatalyst was synthesized and characterized by several methods including XRD, SEM, TEM, ICP, and FT-IR analyses. The γ-Fe2O3@CuFAp has been used as an efficient recyclable magnetic catalyst for synthesis of benzimidazoles. The γ-Fe2O3@CuFAp was conveniently separated from the reaction mixture by an external magnet, and could be reused at least 12 times without any considerable change in catalytic activity.
