“…The refluxing time duration was extended, and the peak at 318 nm gradually declined and vanished within 30 min, indicating that the Ru(III) ions were completely reduced. In this case, the color of reaction mixture changed from dark red to yellow, then to deep green, and ultimately to brown, ending in the dark-black coloring of the Ru(0) species …”

Polyol techniques have recently emerged as viable soft chemical approaches for the production of ultrafine metal crystals. In this work, we described a simple method of ruthenium nanochains ornamented on an octahedral palladium (RuNCs@Oct-Pd) hybrid nanonet assembly synthesized by using polyvinylpyrrolidone (PVP, stabilizing agent) and 1,2-propanediol (1,2-PD, reducing solvent). The prepared nanonet assembly plays a vital role for reduction of toxic nitro substances such as (4-nitrophenol, 4-NP) and hazardous antimicrobial agents (nitrofurantoin, NFT). The morphology of the nanonet assembly was tested by XRD, SEM, FE-TEM, XPS, and UV−vis spectral techniques. The RuNCs@Oct-Pd nanonet assembly demonstrates enhanced catalytic reduction of 4-NP and NFT using NaBH 4 (reductant) at ambient temperature. The RuNCs@Oct-Pd hybrid nanonet assembly exhibited a higher rate constant (k app = 0.4332 s −1 ) and turnover frequency (TOF = 5.0 × 10 −2 s −1 ) than commercial catalysts like Ru/C and Pd/C because of substantial catalytic active sites, high surface-to-volume ratio, rapid surfacehydrogen transfer, and superior stability. Furthermore, the hybrid catalyst in this combination showed outstanding durability and reusability, making it suitable for real-world applications.

“…A bimetallic Re−Ru@f-MWCNT catalyst has recently been reported as a novel sensing platform for nitrofurantoin (NFT, antibiotic) and flutamide (FLT, antitestosterone) medicines by our group (Figure 20). 182 The particle sizes were calculated for Re NP (1.5−2.8 ± 0.1 nm) and Ru NP (1.8 ± 0.2 nm) using FE-TEM data. The ultrafine Re−Ru NPs have a stronger interaction with f-MWCNT support, resulting in synergetic interaction that boosts electroanalytical behavior.…”

In this review, ruthenium nanoparticles (Ru NPs)-based functional nanomaterials have attractive electrocatalytic characteristics and they offer considerable potential in a number of fields. Ru-based binary or multimetallic NPs are widely utilized for electrode modification because of their unique electrocatalytic properties, enhanced surface-area-to-volume ratio, and synergistic effect between two metals provides as an effective improved electrode sensor. This perspective review suggests the current research and development of Ru-based nanomaterials as a platform for electrochemical (EC) sensing of harmful substances, biomolecules, insecticides, pharmaceuticals, and environmental pollutants. The advantages and limitations of mono-, bi-, and multimetallic Rubased nanocomposites for EC sensors are discussed. Besides, the relevant EC properties and analyte sensing approaches are also presented. On the basis of these insights, we highlighted recent results for synthesizing techniques and EC environmental pollutant sensors from the perspectives of diverse supports, including graphene, carbon nanotubes, silica, semiconductors, metal sulfides, and polymers. Finally, this work overviews the modern improvements in the utilization of Ru-based nanocomposites on the basis for electroanalytical sensors as well as suggestions for the field's future development.

“…2,3 Distinctively, antibiotic drugs used to treat infectious diseases in both animal husbandry and humans are considered one of the key aquatic and food contaminants. 4–6 Nitrofurantoin (NFT) is an antibiotic drug that is produced through a chemical process strategy by 5-nitro-2-furaldehyde and 1-aminohydantoin sulfate, 7,8 and it shows notable activity against Gram-negative and Gram-positive microbes. 9 In line with this, NFT reacts over some bacteriophages, salmonella, Escherichia coli , and Enterobacter.…”
