“…210), (020), and (110) reflections of the crystal RuO2 phase, respectively [26]. The obtained reflections suggest that Oxide A and Oxide B have an orthorhombic structure (JCPDS No: 88−0323), which is in agreement with those previously reported by Refat et al [31] and Alibrahim et al [32]. The D value for oxides A and B was calculated based on the intense Bragg's diffraction line detected in the oxides' XRD diffractograms using Debye-Scherrer's law [27].…”

ABSTRACT. Two mixed-ligand complexes of Ru(III) ions were synthesized and used to generate nanostructured RuO2 oxide. Complex A contains gatifloxacin (L1), the amino acid glycine (L2), and Ru(III) ions in a 1:1:1 ratio. Complex B contains gatifloxacin (L1), the amino acid alanine (L3), and Ru(III) ions in a 1:1:1 ratio. The synthesized complexes were characterized using UV-Visible and IR spectroscopies, molar conductance, elemental analyses, thermogravimetry, XRD, and SEM-EDX techniques. In both complexes, the L1 ligand acts as a bidentate and uses the nitrogen atoms of the piperazine ring to capture the Ru(III) ions, while the L2 and L3 ligands capture the Ru(III) ions using their oxygen atom of the carboxylate group and the nitrogen atom of the amino group. The atmosphere around the Ru(III) ion is octahedral, and the complexes were formulated as [RuL1L2(H2O)2]Cl2 and [RuL1L3(H2O)2]Cl2 for Complex A and Complex B, respectively. Complex A was directly decomposed in air at 600 °C for 3 h to produce RuO2 oxide (Oxide A), and complex B was decomposed under the same conditions to produce RuO2 oxide (Oxide B). Morphologically, oxide A and oxide B have a coral reef-like texture with large holes and cavities. KEY WORDS: Gatifloxacin, Ru(III) ion, Glycine, Alanine, Morphology, RuO2 oxide Bull. Chem. Soc.

“…It has been claimed that both the synthetic method and the precursor of choice have a strong influence on the final performance of rutile-type RuO 2 catalysts in terms of stability and electrocatalytic activity for the water splitting reaction. In fact, it has already been revealed that the synthesis procedure clearly influences the obtained RuO 2 [ 24 , 25 , 26 ], although just a few recent examples have used Ru(II) and Ru(III) complexes as precursors [ 27 , 28 ]. In this sense, we have recently reported the use of Pd and Ru excess in surplus coordination/organometallic complexes prepared in research laboratories [ 29 , 30 ] as precursors for Pd/PdO and Ru/RuO 2 materials.…”

Bifunctional P-Containing RuO2 Catalysts Prepared from Surplus Ru Co-Ordination Complexes and Applied to Zn/Air Batteries

An innovative synthetic route that involves the thermal treatment of selected Ru co−ordination complexes was used to prepare RuO2-based materials with catalytic activity for oxygen reduction (ORR) and oxygen evolution (OER) reactions. Extensive characterization confirmed the presence of Ru metal and RuP3O9 in the materials, with an improved electrocatalytic performance obtained from calcinated [(RuCl2(PPh3)3]. A mechanistic approach for the obtention of such singular blends and for the synergetic contribution of these three species to electrocatalysis is suggested. Catalysts added to carbon−based electrodes were also tested in all−solid and flooded alkaline Zn/air batteries. The former displayed a specific discharge capacity of 10.5 A h g−1 at 250 mA g−1 and a power density of 4.4 kW kg−1 cm−2. Besides, more than 800 discharge/charge cycles were reached in the flooded alkaline Zn/air battery

In this work, the reaction between the drug gatifloxacin (as a ligand) with Ru(III) ions was investigated and the resulting complex was structurally and morphologically characterized. The structural properties of the complex were assessed using elemental analyses, molar conductance, thermogravimetry, UV-Vis, and IR spectroscopies, where the morphological characteristics were evaluated using SEM-EDX and XRD methods. The analyses suggested that two ligand molecules were coordinated to the Ru(III) ion via the nitrogen atoms of piperazine rings. The complex was formulated as [Ru(L)2(Cl)2]Cl, where the Ru(III) ion has a six-coordinate mode, and the coordination sphere is complemented by chlorine atoms. The interaction of the ligand with the Ru(III) ions leads to the product having an organized smooth plate-like structure with a main diameter of 39.42 nm. The RuO2 oxide in the nanoscale range was generated by the thermal decomposition of the [Ru(L)2(Cl)2]Cl complex at 600 oC for 3 hours. SEM micrographs indicated that the RuO2 material possesses uniform and organized microstructures with many internal cavities enabling it to be used as a catalyst for the heterogeneous degradation of dyes and organic pollutants.
