HDT of the model diesel feed over Ir-modified Zr-SBA-15 catalysts
(Elsevier, 2019-03)
Iridium catalyst using different zirconium modified-SBA-15 supports were tested in the HDT of tetralin and typical sulfur and nitrogen compounds present in diesel feed. The zirconium modified-SBA-15 supports were synthesized ...
Characterization and catalytic performance of rhenium oxide-based catalysts supported on borated silica-alumina
(Elsevier Science BvAmsterdamHolanda, 2004)
In-Situ DRIFT Study of Au-Ir/Ceria Catalysts: Activity and Stability for CO Oxidation
(Springer/plenum Publishers, 2016-02)
Monometallic gold and iridium, and bimetallic gold-iridium on ceria catalysts were synthesized by deposition-precipitation with urea. The activity of these ceria supported catalysts for CO oxidation was: Au-Ir >> Au > Ir. ...
Pt–Ir/Al2O3 catalysts for the ring opening of naphthenes. Performance as a function of time
(Springer, 2019-06)
The catalytic performance of a Pt?Ir/Al2O3 catalyst for the selective ring opening of decalin was studied as a function of time. Fresh and used catalysts were evaluated with the reaction tests of cyclohexane dehydrogenation ...
Syntheses and characterization of binuclear Rh-2, Ir-2 and RhIr complexes containing dimethyl phosphonate and pyrazolate bridging ligands
(ROYAL SOC CHEMISTRY, 1996)
The reaction of [Ir(eta(5)-C(5)Me(5))I{PO(OMe)(2)}{P(OH)OMe)(2)}] with pyrazole (Hpz) in the presence of AgPF6 gave [Ir(eta(5)-C(5)Me(5)){PO(OMe)(2)}{P(OH)(OMe)(2)}(Hpz)]PF6 1. Deprotonation of 1 with sodium carbonate ...
Influence of metallic oxides on ethanol oxidation
(Elsevier, 2014-05-27)
An improvement in ethanol oxidation electrocatalysis is possible with multifunctional Ptbased combinations. Thus, the addition to Pt of Sn, Ir or Ni enhances the ethanol oxidation reaction (EO) and shifts the onset oxidation ...
Selective oxidation of ethanol on V-MCM-41 catalysts
(Elsevier Science, 2019-10-19)
Catalysts V-MCM-41 with different V contents (0.09-0.90 wt.%), synthesized by the template ion-exchange (TIE) method, have been investigated for acetaldehyde production by selective oxidation of ethanol, studying the effects ...
Ir-Sn-Sb-O Electrocatalyst for Oxygen Evolution Reaction: Physicochemical Characterization and Performance in Water Electrolysis Single Cell with Solid Polymer Electrolyte
(MDPI, 2020-05)
Mixed oxide Ir-Sn-Sb-O electrocatalyst was synthesized using thermal decomposition
from chloride precursors in ethanol. Our previous results showed that Ir-Sn-Sb-O possesses
electrocatalytic activity for an oxygen evolution ...
Preparation and evaluation of carbon-supported catalysts for ethanol oxidation
(Springer, 2013-06)
Supported PtSnIr/C, PtSn/C, and IrSn/C catalysts with potential application in a direct alcohol fuel cell were prepared by chemical reduction employing Pechini methodology. The catalyst particles were characterized by ...
Novel preparation of Titania-Modified CMK-3 nanostructured material as support for Ir catalyst applied in hydrodenitrogenation of indole
(Springer, 2017-04)
Iridium catalyst was prepared using a novel titanium oxide-CMK-3 support synthesized as a replica of Ti-SBA-15. The catalyst was applied in the hydrodenitrogenation of indole. The activity was compared with an iridium ...
