We synthesized functionalized f-SiO2@[email protected] catalyst through decorating graphene oxide surface using SiO2 sphere with the help of ethylenediamine ligand and chelation with CoCl2.6H2O for increasing the catalyst activity to produce heterogenous catalyst. The heterogenous catalyst was characterized by FT-IR, XRD, SEM, Raman spectra, and TGA. We assessed activity of the catalyst in the synthesis of indenopyrazolones and results demonstrated high activity for the catalyst. The ability of the catalyst to increase the yield and reduction in reaction time as well as high catalytic activity, and recycling are prominent advantages of the catalyst.
