A dielectric barrier discharge (DBD) plasma reactor: an efficient tool to prepare novel RuO₂nanorods

Ultrafine Ruthenium Oxide Nanoparticles Supported on Molybdenum Oxide Nanosheets as Highly Efficient Electrocatalyst for Hydrogen Evolution in Acidic Medium

“…Figure d shows that the high‐resolution O 1s spectrum which is deconvoluted into two peaks at 529.4 and 531.1 eV. They are related to Mo−O/Ru−O bonds and chemisorbed water molecules on metal/metal oxide surfaces, indicating the presence of Ru and Mo oxides, respectively ,. Table gives a summary of the atomic percentage (at %) of Mo, Ru and O in MoO 3 , RuO 2 and MoO 3 @RuO 2 −40.…”

Dielectric Barrier Discharge (DBD) Plasma Assisted Synthesis of Ag2O Nanomaterials and Ag2O/RuO2 Nanocomposites

“…When the concentration of NaOH was increased from 0.75 to 1.0 M, the length and thickness of the particles also increased, resulting in a flower-like and leaf-like morphology, respectively. On the other hand, the synthesis of RuO 2 NMs (band gap of about 2.5 eV) by DBD plasma resulted in one dimensional structure such as nanosheets (see Figure S1b in Supplementary Materials) due to the potential gradient inside the reactor [ 15 ]. Accumulation of static electric charges results in the stacking and compression of the nucleated particles in response to the created electric potential, leading to sheet-like structures ( Figure 4 b).…”

“…Ruthenium (IV) oxide (RuO 2 ) itself is an excellent candidate material for catalysis, field emission displays, fuel cells and supercapacitor applications [ 6 , 7 , 8 ]. There are varieties of methods such as wet chemical [ 9 ], biological [ 10 ], thermal deposition [ 11 ], thin film-based and recently plasma-mediated routes [ 12 , 13 , 14 , 15 , 16 , 17 ] to prepare nanomaterials are currently used. The main advantage of applying plasma-based techniques to synthesize nanomaterials is the possibility of controlling the growth, surface chemistry and surface morphology.…”

Resolving ruthenium: XPS studies of common ruthenium materials

“…From the literature, it is apparent that many papers give little appreciation to the physics of the photoemission process and the resulting spin‐orbit splitting (SOS) of non s ‐levels, or satellite structure from screened states, often leading to poorly fitted spectra and potentially erroneous assignments …”

“…From the literature, it is apparent that many papers give little appreciation to the physics of the photoemission process and the resulting spin-orbit splitting (SOS) of non s-levels, or satellite structure from screened states, often leading to poorly fitted spectra and potentially erroneous assignments. [18][19][20] The purpose of this paper is therefore (i) to provide a selfconsistent aid in elucidation of ruthenium chemical states, (ii) expand on the available Ru(3d) binding energies by the addition of the 3p levels as determined from bulk standards and (iii) determine accurate core level binding energies and SOS through analysis with the latest generation of photoelectron spectrometer.…”
