A series of bare ZrO2 materials composed either of monoclinic or tetragonal phase with the size of crystallites varying between 3.7 and 43.4 nm were prepared by precipitation, hydrothermal or thermal calcination methods. The samples were characterize

Rhenium oxide-based catalysts are highly active olefin metathesis catalysts. However, sublimation of rhenium heptoxide during the calcination step can lead to the loss of rhenium. We show that rhenium losses in Re-Si-Al mixed oxide catalysts synthesi

A series of catalysts based on Ni supported on mesoporous La 2 O 3 –ZrO 2 was prepared and tested in low-temperature (400 °C) dry reforming of methane for 100 h on stream. The catalysts were obtained from the same precursor by calcining in either

The wet impregnation of ammonium heptamolybdate onto silica-alumina is used to prepare MoO3/SiO2-Al2O3 heterogeneous metathesis catalysts. The preparation is inspected in details in conjunction with physico-chemical characterization tools with the ai

Molybdenum oxide supported on mesoporous silica-alumina is an efficient catalyst for the light olefins metathesis. Preparation via the classical wet impregnation with ammonium heptamolybdate (AHM) suffers from several downsides related to the control

Mesoporous Re–Si–Al, Re–Al, and Re–Si mixed oxides were obtained via a one-step non-hydrolytic sol–gel route followed by calcination. The texture and surface properties of the resulting catalysts were characterized by a combination of EDX,

The title catalysts are prepared by spraying of aqueous solutions containing Si(OEt)4, ethanol, a block copolymer (Brij58), AlCl3, and H3PMo12O40 or MoCl5, followed by fast drying of the obtained aerosol and calcination of the produced solid at 550

MoO3-based materials are known to be appropriate catalysts for the heterogeneous metathesis of light olefins. Classical preparation methods involve the deposition of a Mo oxide phase on the surface of preformed support via impregnation, grafting or t
