Abstract: The Knoevenagel condensation reaction has wide applications ranging from the manufacture of basic chemicals to pharmaceutical intermediates. In this study, we developed an efficient and magnetic bimetallic NiCo₂O₄ nanocatalyst by coprecipitation. When used in the Knoevenagel condensation between various benzaldehydes and malononitrile, the catalyst exhibited excellent catalytic performance with 99% conversion and 99% selectivity under mild conditions. It can be easily recovered with a magnet and recycled for 20 runs without significant loss of activity. We expect that the catalyst will find large-scale industrial applications.

Key words: NiCo₂O₄ catalyst; Spinel; Knoevenagel condensation; Heterogeneous catalysis
