摘要

具有不同尺寸、形状、组成和形态的杂化纳米材料在众多的物理、化学、电和磁尖中具有重要的意义。多壁碳纳米管(MWCNTs)可以用各种金属装饰，以产生纳米杂化物，以获得领先的高科技应用所需的特性。本研究包括一种低成本的湿化学方法来制备赤铁矿基(α-Fe2O3- MWCNTs)纳米杂化物。采用XRD、FTIR、SEM、VSM和EDX等方法对其理化性质进行了研究。结果表明，MWCNTs表面形成了装饰良好的赤铁矿纳米晶体(尺寸约26nm)。磁性行为表明，该铁磁性材料的饱和、剩余磁化强度和矫顽力分别为~ 1.2 emu/g、0.5 emu/g和200 Oersted，这使其成为先进储能器件的合适竞争者。

Hematite Decorated MWCNT Nanohybrids: A Facile Synthesis

Hybrid nanomaterials with different sizes, shapes, compositions, and morphology have gained importance for numerous physicochemical, electrical and magnetic acumens. Multi-Walled Carbon nanotubes (MWCNTs) can be decorated with various metals to produce nanohybrids to attain desired features for leading high-tech applications. The presented research work comprises a cost- effective wet chemical method to fabricate Hematite based (α-Fe2O3- MWCNTs) nanohybrids. Physicochemical characteristics were studied by XRD, FTIR, SEM and VSM, and EDX, respectively. Results showed well-decorated hematite nanocrystals (size ~ 26nm) on the surface of MWCNTs. Magnetic behaviors exhibited a ferromagnetic material with saturation and remnant magnetization and coercivity of ~ 1.2 emu/g, 0.5 emu/g and 200 Oersted respectively, which makes it a suitable contender in advanced energy storage devices.
