Growth of RuO2 by electrochemical and gas-phase oxidation of an Ru(0001) surface

Hydrogen Evolution Electrocatalysis on AgPd(111) Alloys

“…Figure 3 shows a characteristic voltammogram of the Ru (0001) electrode, used as substrate for the AgPd(111) alloys (thin line). The curve agrees with literature data for Ru (0001) in sulfuric acid [20,21], indicating a clean system and a well-ordered electrode surface. Sulfate is adsorbed in an ordered layer in the negative potential region [22] until surface oxidation starts at about 0.2 V vs. SCE.…”

Raman scattering characterization of well‐aligned RuO2 and IrO2 nanocrystals

“…Different RuO 2 phases have been prepared by MOCVD, 31,32 RFMS, 33,34 pulsed laser deposition, 35 molecular beam epitaxy, 36 electroplating followed by annealing, 37 pyrolysis of metalorganics, 38 reduction of RuO 4 26 and electrochemical oxidation of Ru metal surface. 39 In the following section, we will summarize the Raman scattering results of nanoscale RuO 2 deposited by MOCVD and RFMS techniques.…”

Coadsorption of oxygen, gold and carbon monoxide on Ru(0001) and CO2 formation: A thermal desorption study

“…O(1 · 1)/Ru(0 0 0 1) surface can accommodate additional oxygen in subsurface region with apparent coverages of several monolayers [25,26] after adsorption at temperatures above 600 K. Ruthenium oxide formation, observed at very high oxygen exposures, is achieved by using exposures of several thousands of Langmuirs of NO 2 [26,27] or several millions of Langmuirs of molecular oxygen [11] at elevated temperatures. Oxide grows as striped domains of RuO 2 (1 1 0) phase that coexist with O(1 · 1) on the Ru(0 0 0 1) surface [11,28].…”
