    The Extremely High Specificity of N-Methyldicyclohexylamine for the Production of the Large-Pore Microporous AFI Material

    We describe a highly efficient synthesis of microporous aluminophosphate AlPO4-5 and its heteroatom-substituted variants, using N-methyldicyclohexylamine as a structure-directing agent that, in addition, does not...

    Direct Hydrothermal Conversion of High-Silica Faujausite and Zeolite β to ZSM-5 and Its Catalytic Performance

    In the absence of a structure-directing organic molecule, aluminosilicate ZSM-5 is produced directly from high-silica zeolite Y or zeolite β by a simple hydrothermal treatment of the alkali metal hydroxide-tre...

    Towards molecular sieve inorganic catalysts that are akin to enzymes: studies of a selective cyclo-dimerization over ferrierite at ambient temperature

    The solid-acid (Brønsted)-catalyzed cyclo-dimerization of 3-hydroxy-3-methylbutan-2-one (HMB) over a synthetic ferrierite molecular sieve is reported. HMB is a stable liquid at ambient temperatures but in acid...

    Facile heterogenisation of molecular Ti(OSiPh3)4 to form a highly active epoxidation catalyst

    The simple grafting procedure of Ti(OSiPh3)4 onto the internal surface of MCM-41 to produce an epoxidation catalyst of high activity and selectivity is described. The presence of the phenyl groups on each titaniu...

    Redox solid catalysts for the selective oxidation of cyclohexane in air

    The selective oxidation of cyclohexane to cyclohexanol, cyclohexanone and adipic acid using molecular oxygen as the oxidant and at moderate temperatures (403 K) has been investigated over four different cobalt...
