A simple one step green procedure is intended to investigate for the first time by employing ruthenium oxide nanoparticles (RuO₂ NPs) derived from Catharanthus roseus (CR) and Moringa oleifera (MO) leaves and evaluate their catalytic—degradation of MB dye, antibacterial screening and in vitro antioxidant assays. The as-synthesized RuO₂ NPs were characterized by XRD, HR-TEM, FT-IR, EDX and UV–Visible spectrometer. The HR-TEM image reveals spherical morphology with average particle size 5.6 nm (CR-RuO₂ NP) and 4.6 nm (MO-RuO₂ NP). The research findings of the current study elucidates the superiority of CR-RuO₂ NPs and well exhibited towards scavenging activity, admirable anti-bacterial effect against K. pneumonia (21.6 ± 0.24 mm), and catalytic degradation percentage as 79.02%. The adsorption kinetics indeed suggest more impressive pseudo-second-order kinetic model than Lagergren first-order kinetics at 10 ppm concentration of MB dye. Our results thus provide a platform for further research on the applications of RuO₂ NPs as disinfectant and better catalyst.

一种简单的一步绿色程序旨在通过使用源自长春花（CR）和辣木（MO）叶片的氧化钌纳米颗粒（RuO ₂ NPs）进行首次研究，并评估它们的催化降解MB染料，抗菌筛选和体外抗氧化剂测定。通过XRD，HR-TEM，FT-IR，EDX和紫外可见光谱仪对合成的RuO ₂ NP进行了表征。HR-TEM图像显示出球形形态，平均粒径为5.6 nm（CR-RuO ₂ NP）和4.6 nm（MO-RuO ₂ NP）。本研究的研究结果阐明了CR-RuO ₂的优越性NPs和NPs具有清除活性，对肺炎克雷伯菌具有令人钦佩的抗菌作用（21.6±0.24 mm），催化降解率为79.02％。实际上，在10 ppm的MB染料浓度下，吸附动力学确实比Lagergren一级动力学更令人印象深刻的伪二级动力学模型。因此，我们的结果为进一步研究RuO ₂ NP作为消毒剂和更好的催化剂的应用提供了平台。
