Pt-Ir/HY and Pt-Mg-Ir/Al2O3 catalysts were studied and tested in the reaction of ring opening of decalin.The acidity of the alumina support was modified by addition of 3% Mg and the acidity of the zeolite by ion exchange ...

The electro-oxidation of methanol at Pt-Ir and Pt deposits, and at Pt, Ir, and Pt-Ir wires in sulfuric acid solution was studied by cyclic voltammetry (CV), and in the case of Pt-Ir and Pt electrodeposits, also with the ...

The influence of Ir content on the properties of Pt-Ir/Al2O3 and Pt-Ir/TiO2 catalysts for selective ring opening of naphthenes was studied. It was found that these catalysts display a strong Pt–Ir interaction but only a ...

The aim of this study was to study the ring opening of decalin at 300 and 350 °C using Pt-Ir/HY zeolite catalysts. Monometallic Ir(x = 1.0, 1.5%wt) and Pt(y = 1.0, 1.5%wt) and bimetallic Ir(1.0)Pt(y = 0.5, 1.0, 1.5%wt), ...

The influence of the supports (Al2O3, TiO2 and SiO2) on the activity and selectivity of Pt-Ir catalysts for the ring opening of decalin was studied. It was found that the properties of the supports strongly influence the ...

The electro-reduction of nitrate ions in acid medium on Pt, Ir and on a 70:30 Pt, Ir alloy was studied by cyclic voltammetry. The alloy has a higher activity than the pure metals, which was interpreted as being due to ...

This study investigates the promoting effect of PtSnIr/C (1:1:1) electrocatalyst anode, prepared by polymeric precursor method, on the ethanol oxidation reaction in a direct ethanol fuel cell (DEFC). All of the materials ...
