This project reports a simple procedure for the synthesis and characterization of neodymium on MCM-41 magnetic nanoparticles (MCM-41 MNC) as a reusable nanocatalyst. Firstly, MCM-41 MNC prepared by Fe3O4-dopping into mesoporous MCM-41 channels. Then, a novel neodymium Schiff base complex was immobilized on MCM-41 MNC. Finaly, this catalyst (Nd-LArg-5BrSalen@MNC) was used as magnetically recoverable nanocatalyst in the synthesis of tetrazoles. This nanocatalyst was characterized via TGA, TEM, SEM, FT-IR, SEM-EDS, VSM, ICP, XRD, WDX, and BET techniques. All tetrazole products were synthesized with high yield in short time and were identified by 1H NMR, FT-IR and physical properties. Nd-LArg-5BrSalen@MNC nanocatalyst can be isolated and reused for several times consecutively without considerable loss of its catalytic activity. The recycled catalyst was characterized by SEM, EDS, WDX, XRD and FT-IR techniques. Also, the antifungal activity of the some tetrazole derivatives was studied against Fusarium oxysporum (rot disease of chickpea root) and Botrytis cinerea (gray mold of strawberry) using the paper disk method on PDA culture medium.
