Summary: A thermally stable Pd/SBA-15 catalyst prepared using the sol-immobilization method shows excellent catalytic activity and stability for methane combustion at low temperatures, with smaller nanoparticles size being essential for higher activity. The presence of water vapor in the reactant mixture negatively affects the catalytic activity of the catalyst, and hydrothermal treatment leads to partial re-dispersion of Pd nanoparticles. This work may provide insights into designing stable metal catalysts for reactions under harsh conditions using porous materials.

Summary: In this study, organosilane-modified benzoxazolium-based ionic liquids were synthesized and immobilized on SBA-15 silica support to form supported ionic liquids (SILs). The structure of SILs was determined using various techniques, and their adsorption abilities were tested in the desulfurization of gasoline samples. The SIL adsorbents showed higher efficiency compared to SBA-15 due to interactions between the supported ionic liquids and thiophene compounds.

Summary: In this study, two new quadripartite nanocomposites were synthesized, consisting of conductive polymer, expanded and functionalized graphene sheets, and magnetic parts. The contiguity of magnetic oxide, conductive polymer, and rare earth metal oxide was investigated. The compounds were characterized using FTIR, XRD, FE-SEM, and EDX, and their electrochemical and magnetic properties were analyzed. The results showed that the use of cerium oxide instead of terbium oxide reduced the magnetic property and increased the current density.
