چکیده مقاله :
In this thesis, palladium intermediate metal complex was synthesized based on silicate nanocavity mcm_41, which was used as efficient and reusable nanocatalysts in carbon-carbon, carbon-nitrogen and carbon-oxygen coupling reactions. Short reaction time, better yield of products, separation of the path of catalysts due to their heterogeneous characteristics and the use of green solvent are some of the advantages of this method. Then, the nature and construction of the catalyst using Fourier transform (FT-IR), energy diffraction measurement (EDX), inductively coupled plasma emission spectrometer (ICP-OES), transmission electron microscopy image (TEM), microscope image - Scanning Electron ( SEM), X-Ray Diffraction (XRD) and Porosimetry measurement of absorption and desorption (BET) were investigated.
