Bifunctional carbon‐based acid catalysts presenting Brønsted and Lewis sites in different proportions were synthesized by grafting mesoporous aluminosilicate patches coexistence with benzyl sulfonic moieties on the solid’s surface. The final bifunctional systems obtained development of a methodology allowing production discontinuous metal‐oxide layer carbon substrate using silica as model oxide before applying optimized procedure for desired alumino‐silica patches. Patches necessary to...
Abstract Metal‐doped hollow silica nanotubes (M‐NT, where M = Ti, Zr, Hf) were successfully synthesized via a straightforward impregnation of pristine with M‐acetylacetonate solutions. After their characterization, the materials tested as heterogeneous catalysts for conversion ethyl levulinate (EL) into γ‐valerolactone (GVL) revealing highly promising activity target reaction. Special emphasis was given on disclosing influence nature acid sites (Lewis or Brønsted) and strength catalytic...
Abstract Carbon nanotubes have been covalently functionalized with catechol moieties through the formation of corresponding aryl radicals obtained by reacting 4‐aminocatechol isoamyl nitrite. The multiwalled carbon in turn used to immobilize Pd(II) ions on its surface forming catechol‐Pd complexes, which were reduced Pd nanoparticles (NPs). so‐obtained hybrid material has characterized means thermogravimetric analysis coupled differential scanning calorimetry (TGA‐DSC), X‐ray photoelectron...
A new straightforward and green approach for the covalent functionalization of multi-walled carbon nanotubes (MWCNTs) was developed. This nanostructure efficiently derivatized by polymerizing proper deep eutectic monomers (DEM), a subclass solvents (DES), based on series mono- bis-vinyl imidazolium salts endowed with different functional groups (–OH, –NH2, –NH3+Br–) in side chain or spacer. Herein, DEM systems played triple role as convenient dispersion media MWCNTs, efficient reactive...
Three different carbon nanoforms (CNFs), single-walled and multi-walled nanotubes (SWCNTs, MWCNTs) nanohorns (CNHs), have been used as supports for the direct polymerization of variable amounts a bis-vinylimidazolium salt. Transmission electron microscopy confirmed that all CNFs act templates on growth polymeric network, which perfectly covers nanocarbons forming cylindrical or spherical (CNHs) coating. The stability these hybrid materials was investigated in conversion CO
A straightforward synthesis of a series hybrid organic-inorganic materials (HOIMs) containing imidazolium moieties was achieved. The preparation the acetate precursor performed in single-step procedure using Debus-Radziszewski reaction. as-synthesized alkoxysilane employed combination with tetraethyl orthosilicate to generate an HOIM presenting high specific surface area. Two different structure-directing agents (SDAs), anionic (sodium dodecyl sulfate (SDS)) or cationic...
Two heterogeneous catalysts were prepared with the aim of following promising path CO 2 fixation onto epoxides. The synthetic procedure involves a radical copolymerization an octavinylsilsesquioxane as inorganic core building block and tetrastyrylporphyrin aluminum chloride monomer (TSP_AlCl) in presence (POSS_TSP_AlCl_imiBr) or absence (POSS_TSP_AlCl) bis-vinylimidazolium bromide salt (bis-imiBr), order to investigate if bifunctional material can display better catalytic performance than...
