In this paper, we report the synthesis of amine modified SiNPs (silica nanoparticles) by a sol–
gel method and the role of synthesized SiO2 as a solid support for the nanocatalyst CuNPs
(copper nanoparticles). The nanocatalyst is characterized by XRD, HRTEM, BET, AFM, SEM,
EDX, UV-vis, FT-IR and TGA techniques. The Cu/SiO2 (catalyst A) serves as an efficient
heterogeneous nanocatalyst exhibiting high catalytic activity for the synthesis of a series of
1, 4-disubstituted-1, 2, 3-triazoles and thioethers. The catalyst A can be recycled and reused …
