Ru-specific promotion in electrodeposited Pt-based bimetallic catalysts for isopropanol electrooxidation [PDF]

RSC Advances
Isopropanol/acetone is a promising electroactive liquid organic hydrogen carrier pair due to its high hydrogen storage capacity (3.4 wt%), low toxicity, and large-scale availability.

Carbon dioxide conversion to fuel over alumina-supported ruthenium catalysts [PDF]

Heliyon
In this study, ruthenium-based catalysts were prepared for CO2 hydrogenation. Incipient-wetness-impregnation of the alumina-support with ruthenium (III) nitrosyl nitrate solution to achieve 0.5 wt% Ru loading on supports was used to prepare these ...

Study on the Reaction Mechanism of RuO_x and Its Enhanced Hydrogen Evolution Reaction Activity. [PDF]

Adv Sci (Weinh)
In situ Raman spectroscopy and DFT calculations reveal that, prior to the onset of HER, the surface of RuOx undergoes reversible reduction and structural reconstruction. The resulting Ru(II)O/Ru(IV)O2 configuration is identified as the true catalytically active species.

CO₂ Hydrogenation: Na Doping Promotes CO and Hydrocarbon Formation over Ru/m-ZrO₂ at Elevated Pressures in Gas Phase Media

Nanomaterials, 2023
Sodium-promoted monoclinic zirconia supported ruthenium catalysts were tested for CO2 hydrogenation at 20 bar and a H2:CO2 ratio of 3:1. Although increasing sodium promotion, from 2.5% to 5% by weight, slightly decreased CO2 conversion (14% to 10%), it ...

Moving from Classical Ru-NHC to Neutral or Charged Rh-NHC Based Catalysts in Olefin Metathesis

Molecules, 2016
Considering the versatility of oxidation states of rhodium together with the successful background of ruthenium-N-heterocyclic carbene based catalysts in olefin metathesis, it is envisaged the exchange of the ruthenium of the latter catalysts by rhodium,
