Synthesis and Structural Properties of Nanoselenium-Supported MCM-41 Material

The authors describe herein a new process for the synthesis of nanoselenium–supported MCM-41 hybrid material. Selenium nanoparticles were synthesized via chemical reduction method that this method is capable of producing spherical selenium nanoparticles of size 20 to 80 nm, under ambient conditions, and covalently bonded to MCM-41 framework by 3-(triethoxysilyl)-propylamine (APTES). The structures, morphology and size of the products were investigated by several characterization techniques such as XRD, SEM, TEM, FT-IR, UV–vis/DRS, Raman spectroscopy, and N2 adsorption–desorption isotherms method. These results demonstrated that Se-MCM-41 is a promising candidate for biosensor, adsorbent, or catalyst.
