Ruthenium Nanoparticles In article number 2206806 by Alexis Bordet, Walter Leitner, and co-workers, the aqueous phase hydrogenation of CO2 to formate using Ru nanoparticles immobilized on supported ionic liquid phases ([email protected]) is reported. A synergistic enhancement catalyst activity productivity observed for sulfonic acid-functionalized [email protected](SO3H-X) materials, rationaliz...

Ni(OH)2 have emerged as important functional materials for solar fuel conversion because of their potential as cost-effective bifunctional catalysts for both hydrogen and oxygen evolution reactions. However, their roles as photocatalysts in the photoinduced charge separation (CS) reactions remain unexplored. In this paper, we investigate the CS dynamics of a newly designed hybrid catalyst by in...

Carbon nanotubes (CNTs) have been investigated in recent years as a catalyst support for proton exchange membrane fuel cells. Improved catalyst activities were observed and attributed to metal-support interactions. We report a study on the kinetics of methanol electro-oxidation on CNT supported Pt-Ru alloy nanoparticles. Alloy catalysts with different compositions, Pt53Ru47/CNT, Pt69Ru31/CNT an...

A highly sensitive sandwich-type electrochemiluminescence (ECL) immunosensor was proposed for the quantitative determination of alpha fetoprotein (AFP) using gold nanoparticles decorated black carbon intercalated reduced graphene oxide (Au-rGO@CB) as sensing platform and nanoporous silver (NPS) loaded Ru(bpy)3(2+) as labels. In this work, intercalation of CB inhibited the accumulation of rGO an...

This paper focused on a novel method of electroless plating ruthenium (Ru) on solid or porous substrates like porous stainless steel (PSS) discs or ceramic tubes. A novel complexing plating bath of Ru was developed. It is proven that Ru can be deposited directly on these substrates by the bath at a temperature of 328 K and strong alkaline environment. TGA, SEM, EDX and XRD confirmed the success...

Developing highly efficient, cost-effective, and stable electrocatalysts for hydrogen evolution reaction (HER) is of considerable importance but remains challenging. Herein, we report the fabrication a robust Ru-based electrocatalyst, which comprises heterostructured Ru-Ru2P nanoparticles that are embedded in N,P-codoped carbon nanofibers (CNFs), through synthetic strategy involving electrospin...

In the last two decades, the only inorganic non-oxide materials that have attracted significant attention for incorporation in low power electrochromic displays are those belonging to the metal hexacyanoferrate (HCNF) family. In the HCNF family, Prussian Blue (PB) is by far the most studied electrochromic material. In contrast, Ruthenium Purple (RuP) has not been explored for electrochromic dis...

Ru/CNF catalysts of different Ru nanoparticle (NP) sizes (0.9-2.7 nm) were assessed for their performance in continuous supercritical water gasification (SCWG) glycerol. A structure sensitivity was demonstrated, with high initial turnover frequencies (TOF) NPs smaller than 1.2 nm. Deactivation happens essentially through: 1) coking, which occurs more readily at low surface densities and is limi...

Development of high-performance pH-universal electrocatalyst for hydrogen evolution reaction (HER) is a vital step towards economy but remains major challenge. Herein, the Ru decorated Co nanoparticles supported by N-doped carbon sheets (Ru/[email protected]) are prepared galvanic exchange and display remarkable performance HER. In 1.0 M KOH, 0.01 PBS 0.5 H2SO4, respectively, Ru/[email protecte...
