Design, fabrication and characterization of mesoporous yolk-shell nanocomposites as a sustainable heterogeneous nanocatalyst for synthesis of ortho-aminocarbonitrile tetrahydronaphthalenes.

ABSTRACT: A new structure of mesoporous spherical nanocomposites was designed and easily prepared from the reaction between NiCuFe₂O₄ nanoparticles and mesoporous silica in three steps. The prepared multi-yolk@shell NiCuFe₂O₄@mSiO₂ mesoporous sphere was characterized by using FT-IR, XRD, VSM, EDX, BET, FE-SEM and HR-TEM techniques. This unique mesoporous nanocomposite sphere as a heterogeneous nanocatalyst has demonstrated highly catalytic activity for the green synthesis of tetrahydronaphthalene derivatives in 92-98% yields at reaction times of 60-75 min. This process was carried out through multi-component reaction of the cyclic ketone, malononitrile and aromatic aldehyde under solvent-free conditions. Furthermore, the procedure was optimized
