Abstract

Pd nanoparticles (NPs)/reduced graphene oxide (RGO) nanocomposite was prepared in a one-pot process by using Euphorbia stenoclada extract as antioxidant media in the absence of any surfactant, dangerous reactants or using external energy input. Catalytic potential of the fabricated Pd-RGO nanocomposite was examined for the degradation of environmental contaminants including Cr(VI), 4-nitrophenol (4-NP), Congo red (CR), methylene blue (MB) and methyl orange (MO). The Pd-RGO nanocomposite has been thoroughly characterized by employing X-ray diffraction, UV–Vis and TEM studies. Furthermore, recyclability and reusability aspects of the nanocomposite were monitored for multiple uses without much change in catalytic activity.

摘要

在没有任何表面活性剂，危险反应物的情况下或使用外部能量输入的情况下，使用大戟甜菊提取物作为抗氧化剂介质，通过一锅法制备Pd纳米颗粒（NPs）/还原氧化石墨烯（RGO）纳米复合材料。检查了制备的Pd-RGO纳米复合材料的催化潜力，以评估环境污染物的降解情况，包括Cr（VI），4-硝基苯酚（4-NP），刚果红（CR），亚甲基蓝（MB）和甲基橙（MO）。Pd-RGO纳米复合材料已通过X射线衍射，UV-Vis和TEM研究得到了充分表征。此外，对纳米复合材料的可回收性和可重复使用性方面进行了多次使用监测，而催化活性没有太大变化。
