The reduction of palladium ions by silicon hydride groups grafted to the surface of silica matrices was applied for the synthesis of palladium-containing nanocomposites. Ordered mesoporous silicas, such as MCM-41 and SBA-15, along with silochrom type silica were used as supports for palladium nanoparticles in order to obtain encapsulated in pores metal particles. The synthesized nanocomposites have been studied by IR-spectroscopy, X-ray diffraction analysis, low-temperature nitrogen adsorption and transmission electron microscopy.

“…34 Silicas chemically modified with N-allyl-(7a), N-phenyl-(7b) and N-benzoyl-N H -propylcarbamides (7c) have been recommended for sorption determination of gold(III). 35 Silochrome C-80 (fraction of 0.1 ± 0.2 mm with pore diameter of *50 nm) served as a matrix. According to elemental analysis, the surface concentration of grafted groups was 0.12, 0.11 and 0.10 mmol g 71 for adsorbents 7a, 7b and 7c, respectively.…”

The synthesis and physico-chemical characteristics of thiol-functionalized mesoporous silicates MCM-41 and SBA-15 are described. The sorption properties of the materials with respect to noble metal ions, in particular palladium(II) from hydrochloric acid solutions have been studied. The materials obtained have been characterized using a complex of physical and chemical methods before and after functionalization. The evaluation of the sorption capacity of the obtained sorbents with respect to Pd(II) ions has been performed. Experimental results show high sorption activity of thiol-functionalized mesoporous silica.
