Direct synthesis and the morphological control of highly ordered mesoporous AlSBA-15 using urea-tetrachloroaluminate as a novel aluminum source
The synthesis of AlSBA-15 under mild acidic conditions was performed through adjusting the molar H2O/HCl ratio, which indicates the formation of Si–O–Al linkages that lead to isomorphous substitutionExpand
A palladium(II) 4-hydroxysalicylidene Schiff-base complex anchored on functionalized MCM-41: An efficient heterogeneous catalyst for the epoxidation of olefins
Abstract Synthetic procedures are described for anchoring of N-(3-(trimethoxysilyl)-propylethylenediamine on the surface of the mesoporous silica, MCM-41 (MCM-41-N). The condensation ofExpand
Evaluation of solution and rheological properties for hydrophobically associated polyacrylamide copolymer as a promised enhanced oil recovery candidate
Abstract Crude oil is the most critical energy source in the world, especially for transportation, provision of heat and light as there has not been a sufficient energy source to replace crude oilExpand
Oxidative desulfurization using graphene and its composites for fuel containing thiophene and its derivatives: An update review
Abstract Oxidative desulfurization, in which the aromatic sulfur containing compounds are oxidized to their analogical sulfones and subsequently extracted, has assured to be one of the exceedinglyExpand
Synthesis and characterization of MCM-41-supported nano zirconia catalysts
Abstract Series of MCM-41 supported sulfated Zirconia (SZ) catalysts with different loadings (2.5–7.5% wt.) were prepared using direct impregnation method. The acquired solid catalysts wereExpand
One-pot template synthesis of Ti–Al-containing mesoporous silicas and their application as potential photocatalytic degradation of chlorophenols
Abstract This article presents preparation, characterization and evaluation of heterogeneous Titanium based alumina mesoporous silica catalysts for the photo degradation of chlorophenols in aqueousExpand
Microwave assisted synthesis of a VOx-modified disordered mesoporous silica for ethylbenzene dehydrogenation in presence of CO2
Abstract The aim of the study was to investigate the effect of different vanadium loading incorporated into hexagonal mesoporous silica (HMS) support on texture, speciation of vanadyl complexes andExpand
Clean transesterification process for biodiesel production using heterogeneous polymer-heteropoly acid nanocatalyst
Abstract In the present study, new hetrogeneous catalysts, in which phosphotungstic acid is chemically bonded to hydrophobic highly crosslinked poly(4-divinylbenzene-co-vinylbenzyl chloride) via aExpand
Polystyrene nanocomposite materials by in situ polymerization into montmorillonite–vinyl monomer interlayers
A different series of new polystyrene–clay nanocomposites have been prepared by grafting polymerization of styrene with vinyl-montmorillonite (MMT) clay. The synthesis was achieved through two steps.Expand
Polymer–organoclay hybrids by polymerization into montmorillonite-vinyl monomer interlayers
A different series of polymer–clay hybrid materials have been prepared by modification of the clay with different vinyl monomers, followed by polymerization of different ratios of vinyl monomers–clayExpand
