Temperature-Scanning Method for the kinetic studies of CO oxidation over ceria-zirconia supported gold catalysts
(ELSEVIER SCIENCE SA, 2015-12-15)
The experimental data of CO oxidation over the series of 2 wt.% Au/Ce1-xZrxO2 (x=0, 0.25, 0.5, 0.75, 1) catalyst were analyzed using a variation of the Temperature Scanning Method with the aim of catalyst's composition ...
Additively manufactured geopolymer structured heterogeneous catalysts for biodiesel production
(2021-06-01)
The manufacturing of non-stochastic (lattice) scaffolds by Direct Ink Writing is attractive for catalytic fluid flow applications, as it enables the optimization of not only the desired chemically active formulation but ...
An optimization study of PtSn/C catalysts applied to direct ethanol fuel cell: Effect of the preparation method on the electrocatalytic activity of the catalysts
(ELSEVIER SCIENCE BVAMSTERDAM, 2012)
The aim of this work was to perform a systematic study of the parameters that can influence the composition, morphology, and catalytic activity of PtSn/C nanoparticles and compare two different methods of nanocatalyst ...

(2021-11-01)
Greener materials have been used in the construction of electrochemical devices, becoming one of the main strands of this scientific development area. Thin films based on natural and renewable sources, such as propolis, ...
Biomass valorization derivatives: Clean esterification of 2-furoic acid using tungstophosphoric acid/zirconia composites as recyclable catalyst
(Elsevier, 2015-07-17)
2-Furoic acid esters, which are biomass derived, are used in the flavoring and fragrance industry or as synthesis intermediates in the pharmaceutical industry. A series of zirconia samples modified with different contents ...
Spectroscopic and catalytic characterization of Pd-In and Pt-In supported on Al2O3 and SiO2, active catalysts for nitrate hydrogenation
(Elsevier Science, 2008-09)
Bimetallic Pt-In and Pd-In catalysts supported on alumina or silica were studied for the reduction of nitrate to N2 in water, using H2 as reducing agent. Characterization results indicate that bimetallic particles with the ...
Trivalent chromium ion removal from aqueous solutions using low-cost zeolitic materials obtained from exhausted FCC catalysts
(Sage Publications, 2011-07)
The hydrothermal treatment of exhausted FCC catalysts with zeolite was optimized by varying the chemical composition of the synthesis mixture. The zeolitic products obtained were used to evaluate their ability for the ...
Bioadditives synthesis from selective glycerol esterification over acidic ion exchange resin as catalyst
(Elsevier Ltd, 2018-04)
In this work, fuel bioadditives production from glycerol esterification with acetic acid was performed over acidic ion exchange resin as acid catalyst in a batch reactor. The influence of several parameters such as ...
