Nickel nanoparticles in AlMCM41 were prepared by the ion exchange and the reduction with H2 gas. Annealing studies were carried out on Ni-AlMCM41 for the better understanding of the morphology, and magnetic properties of nickel nanoparticles depended on the annealing temperature. Products were characterized by transmission electron microscopy (TEM), X-ray powder diffraction (XRD), thermogravimetric analysis (TGA), and SQUID measurements.
