New architecture of supported metallocene catalysts for alkene polymerization
(John Wiley & Sons Inc, 2007-12)
We report the synthesis of a supported metallocene catalyst that exhibits the same activity as a homogeneous catalyst for ethylene polymerization reactions. The key to this new catalytic system is a hybrid organic-inorganic ...
Soluble TTF catalyst for the oxidation of cathode products in Li-Oxygen battery: A chemical scavenger
(Pergamon-Elsevier Science Ltd, 2015-11)
One of the challenges for the success of electric vehicles is to achieve a non aqueous Li-O2 battery efficient in the oxidation of solid Li2O2 during battery charging. Bruce et al. have proposed that soluble tetrathiofulvalene ...
Water-soluble N-heterocyclic carbene platinum(0) complexes: Recyclable catalysts for the hydrosilylation of alkynes in water at room temperature
(American Chemical Society, 2012-04)
The synthesis and characterization of new water-soluble platinum(0) complexes bearing sulfonated N-heterocyclic carbene (NHC) and divinyltetramethylsiloxane (dvtms) ligands are described. These complexes, of the general ...
Photodegradation of soluble and emulsive cutting fluids using TiO 2 as catalyst
(2006-08-09)
This paper describes results of the photo-degradation of three types of soluble and emulsive cutting fluids in an aqueous medium, using TiO2 as catalyst in suspension and UV radiation. The TiO2 proved to be an effective ...
Photodegradation of soluble and emulsive cutting fluids using TiO 2 as catalyst
(2006-08-09)
This paper describes results of the photo-degradation of three types of soluble and emulsive cutting fluids in an aqueous medium, using TiO2 as catalyst in suspension and UV radiation. The TiO2 proved to be an effective ...
“Soluble” vs. “insoluble” Prussian blue based catalysts: influence on Fenton-type treatment
(Royal Society of Chemistry, 2016-05)
The influence of the synthesis procedure of supported Prussian blue nanoparticles (PBNP) on their activity and stability as a Fenton-type catalyst is studied. Hence, two catalysts are synthesized by adsorbing onto a support ...
The Role of Heterogeneous Catalysts in Converting Cellulose to Platform Chemicals
(2020-01-01)
In times of rethinking production processes and consumption habits to minimize the effects of global warming, it is crucial to find alternatives that lead to replacing fossil fuels by renewable materials. The development ...
EQCM and RDE/RRDE Study of Soluble Iron Phthalocyanine Bifunctional Catalyst for the Lithium-Oxygen Battery
(Electrochemical Society, 2017-12)
Soluble iron phtalocyanine (FePc) has been studied as a bifunctional catalyst for the oxygen reduction reaction (ORR) and oxygenevolution (OER) in lithium air cathodes by means of electrogravimetry with shear wave dissipation, ...
Evaluation of KHSO4 as a recyclable catalyst in the production of dehydrated castor oil to be applied in alkyd resins
(Elsevier, 2021-12)
Due to its lower solubility, this work proposes the use of KHSO4 as a re-usable heterogeneous catalyst in the dehydration of castor oil. Refined and degummed castor oil were considered to determine the effect of the ...
PtSn/SiO2 catalysts prepared by surface controlled reactions for the selective hydrogenation of cinnamaldehyde
(Elsevier Science, 2010-05-24)
Tin-modified platinum catalysts were prepared by means of a controlled surface reaction, varying the Sn:Pt atomic ratio between 0 and 0.8. The addition of tin caused a noticeable change both in product distribution and the ...
