Characterization of new Co and Ru on -WC catalysts for Fischer-Tropsch reaction Influence of the carbide surface state
(Journal of Molecular Catalysis A: Chemical, 2017)
Influence of tungsten on the carbon nanotubes growth by CVD process
(Elsevier Science Sa, 2009-06)
The effect of tungsten (W) on the growth of multi-walled carbon nanotubes (MWNTs) using the chemical vapour deposition (CVD) process over a metal Fe-W catalyst incorporated into a silica matrix is reported. A W molar content ...

Borated zirconia modified with ammonium metatungstate as catalyst in alcohol acetylation
(Elsevier Science, 2012-04)
Samples of tungsten-modified borated zirconia were prepared to be used as catalyst in 2-phenoxyethanol acetylation. The borated zirconias were obtained by impregnation of two zirconias (S2 and S4) obtained by the micellar ...
Kinetic study of the selective hydrogenation of 3-hexyne over W–Pd/alumina catalysts
(Springer, 2019-04)
Low loaded W-Pd/Alumina are relatively novel catalysts for performing the selective hydrogenation of alkynes, but there is scarce information on the working mechanism. This work studies the kinetics of the selective ...
Reactivity of Tungsten-aryloxides with Hydrosilane Cocatalysts in Olefin Metathesis
(Sociedade Brasileira de Química, 2002-02-01)
As reatividades dos sistemas [WCl4(OAr)2] (OAr = O-2,6-C3H3Cl2, O-2,6-C6H3F2 e O-C6H3Me2), juntamente com os compostos de silício Ph2SiH2 e polimetilidrosiloxano (PMHS), foram estudadas em reações de metátese. As olefinas ...

Synthesis, characterization, and catalytic properties of a mesostructured lamellar xerogel tungsten oxide phase
(ELSEVIER SCIENCE BV, 2011)
Cetyltrimethylammonium bromide (CTAB) and n-hexadecylamine (HDA) have been used as template in the synthesis of a mesolamellar xerogel tungsten oxide phase (WO(3)/CTAB/HDA). The catalytic properties of the resulting material ...
