Green and selective oxidation reactions catalyzed by kaolinite covalently grafted with Fe(III) pyridine-carboxylate complexes

Synthesis and characterization of novel transition metal complexes with L-Proline and their catalytic activity evaluation towards cyclohexane oxidation

“…In the meantime; the selectivity was decreased sharply with increasing temperature, due to the overoxidation reaction of the K-A oil. Several Fe complexes were reported to catalyze the cyclohexane oxidation under varies reaction conditions [19][20][21]. A comparison between the results obtained in the current study and the previously reported data is Showed in table 4.…”

Kaolinite/TiO2/cobalt(II) Tetracarboxymetallophthalocyanine Nanocomposites as Heterogeneous Photocatalysts for Decomposition of Organic Pollutants Trimethoprim, Caffeine and Prometryn

“…3,24,25 This problem can be mitigated with some procedures, such as the dispersion on inorganic matrices, 17,26,27 such as clay minerals. Clay minerals are attractive materials for many significant applications, due to their physical and chemical properties, including catalysis/photocatalysis and adsorption, 12,28,29 especially kaolinite, whose layered structure provides the possibility of retention of a great variety of compounds to reduce the energy required for the activation of the semiconductor. Catalyst improvement via immobilization might also be due to the force field between the support and the TiO 2 particles that inhibits the recombination of electron-hole pairs.…”

Covalent grafting of pyridine-2-methanol into kaolinite layers

“…These processes, grafting reactions, which mainly take place on the octahedral sheets of kaolinite by forming covalent bonds (Al-O-C bonds) between organic molecules and inner-surface hydroxyls allows us to obtain thermally and chemically stable materials. There are gradually increasing applications of grafting hybrid materials as a new class of interlamellar modification of kaolinite which may be used as catalyst, adsorbent and electrode component [54][55][56]. Kaolinite-based polymer nanocomposites, the products of interaction between kaolinite and organic polymer emerge as a new class of interlamellar modification of kaolinite and exhibit enhanced properties, including thermal stability, electric performance, conductivity, stiffness, strength, tensile, barrier, chemical resistance and fire retardant [57][58][59][60].…”
