A novel, potent, efficient, and reusable heterogeneous nano-catalyst was prepared and grafted nickel into MCM-functionalized 1,2,3-Triazol-4-ylmethanamine (MCM-TA@Ni). The catalyst was characterized by various physico-chemical analysis such as Fourier transform infrared spectroscopy, scanning electron microscopy, transmission electron microscopy, X-ray diffraction, thermo gravimetric analysis, Brunauer–Emmett–Teller (BET), atomic absorption spectroscopy, and energy dispersive X ray spectroscopy techniques. The catalytic activity of this recoverable nano-catalyst was studied for the carbon–carbon bond formation (Suzuki–Miyaura).
