Synthesis and characterization of semiconductor nanoparticles in MCM-41 zeolite host with hydrothermal and ion exchange methods

An aluminosilicate with the MCM-41 structure (AlMCM-41) was used as a host for the synthesis of Cobalt sulfide nanoparticles. Cobalt sulfide nanoparticles were introduced in host by ion exchange and hydrothermal methods. Products (CoSAlMCM-41) were characterized by XRD, SEM, EDX, IR, BET and UV-Visible spectroscopy. The Results show that zeolite acts as a template for nanoparticles by hydrothermal synthesis and they grow outside the mesopore AlMCM-41 matrix by ion exchange methods.
