Particle size dependence of oxygen evolution reaction on nanocrystalline RuO2 and Ru0.8Co0.2O2−x

Beyond the volcano limitations in electrocatalysis – oxygen evolution reaction

“…4) cation modified ruthenia materials show a greater activity compared with conventional ruthenia. 21 The results of the DFT modelling rationalize the effect of the introduction of Ni or Co on the ruthenia surface. The presence of Ni or Co at the cus positions has only negligible effect on the binding properties of the predominantly Ru composed surface.…”

The Role of TiO2Doping on RuO2-Coated Electrodes for the Water Oxidation Reaction

“…8 In particular, RuO 2 exhibits high catalytic performance for water oxidation with a moderate overpotential and RuO 2 coated electrodes are, thus, one of the most studied catalytic metal oxides for the oxygen evolution reaction (OER). [9][10][11][12][13][14][15][16][17] Moreover, RuO 2 exhibits various interesting properties such as metallic conductivity, low resistivity (3-5 10 -5 Ω cm 18 ), high thermal stability, and high resistance to chemical corrosion, which provides reasonable long-term stability. 22 complemented with the chemically sensitive X-ray photoelectron spectroscopy (XPS), which is extensively used for material characterization.…”

Effect of Adding CeO2 to RuO2–IrO2 Mixed Nanocatalysts: Activity towards the Oxygen Evolution Reaction and Stability in Acidic Media

“…IrO 2 has al ower activity than RuO 2 ,b ut is often preferred, as its long-terms tabilityi s significantly highert han that of RuO 2 .B oth catalysts synthesized by using different methods have largely been studied individually or in mixed oxides. [7,[10][11][12][13][14][15][16] Furthermore, somei nvestigationsh ave aimed at decreasing the amounts of ruthenium and iridium noble and scarce metals used by adding am ore abundant third" diluting" elementt om inimize the cost of the anode catalystw hile maintaining the catalytic properties. [14,[17][18][19][20][21] In our previousw ork, we described an environmentally friendly synthesis approach that avoids the use of any toxic solvent, [22] so as to obtain ruthenium-iridium-oxidea node materials that show high electrocatalytic activities and improved stabilities for ruthenium compositionsh ighert han 70 mol %.…”
