摘要
本文研究了用杏仁胶介导的绿色溶液燃烧法制备Bi2O3/MgO/Fe2O3 (BMF)异质结纳米复合材料。利用光谱技术研究了纳米复合光催化剂的光学性质和结构特征;P-XRD研究证实了NPs的物相形成和结晶性质,发现其平均粒径为28 nm。合成的纳米复合材料的表面形貌包括可见的孔隙、空隙和团聚体。利用电化学分析(CV和EIS技术)在0.01 ~ 0.05 V/s扫描速率下,对制备的BMF纳米复合材料-石墨膏电极在0.1 M KCl溶液中的有效电位进行了研究。此外,BMF材料的传感器活性首次用于碱性介质中浓度为1-5 mM的扑热息痛传感器研究。在紫外光的照射下,用50 mg的BMF纳米复合材料对20 ppm的Fast Orange Red (for)染料进行了光催化降解。这些分析开始为设计用于环境清理的多功能长期应用材料提供一些见解。
Enhanced electrochemical sensor and photodegradation of industrial wastewater by Almond gum assisted synthesis of Bi2O3/MgO/Fe2O3 nanocomposites
The present investigation focused on a development of Bi2O3/MgO/Fe2O3 (BMF) heterojunction nanocomposites by Almond gum mediated green solution combustion process. The optical and structural characterizations of nanocomposite-photocatalysts were studied by spectral techniques; P-XRD study confirms the phase formation and crystalline nature of NPs with its average particle size was found to be 28 nm. The surface morphology of synthesized nanocomposites comprises visible pores, voids and agglomeration obtained by SEM technique. The effective potential investigation of prepared BMF nanocomposite-graphite paste electrode in 0.1 M KCl solution was achieved using electrochemical analysis (CV and EIS techniques) in the different scan rates 0.01–0.05 V/s. Further, the sensor activity of BMF material was examined first time towards paracetamol sensor studies in alkaline medium for quantities of 1–5 mM concentrations. The photocatalytic degradation activity was carried out for 20 ppm of Fast Orange Red (FOR) dye with 50 mg of BMF nanocomposite under irradiation of UV light. These analysis initiates to provide some insights into the design of material for multifunctional long-term applications for environmental clean-up.
