Abstract

The α-Al₂O₃ nano-sized particles were generated employing a combustion reaction using sucrose and graphene oxide as fuel precursors. The synthesized α-Al₂O₃ material was analyzed using scanning electron microscopy (SEM), brunauer-emmett-teller (BET), X-ray diffraction (XRD), dynamic light scattering (DLS), and high-resolution transmission electron microscopy (TEM) techniques. XRD study identified α-Al₂O₃ nanocrystals from aluminum oxide. The results of the SEM and TEM investigations demonstrated that the sucrose samples had particle sizes in the nanoscale range. The study found that higher sucrose concentrations resulted in smaller α-Al₂O₃ particles. The α-Al₂O₃ nano-powder had an average diameter of less than 30 nm. Sucrose and GO were coupled for the first time to fabricate nanosized α-Al₂O₃ powders. The findings may pave the way for new methods of producing stable aluminum nanoparticles in α-phase, which might be useful in a variety of applications.

以蔗糖和氧化石墨烯为燃料前驱体，通过燃烧反应合成纳米α-Al2O3

以蔗糖和氧化石墨烯为燃料前驱体，通过燃烧反应制备α-Al2O3纳米颗粒。采用扫描电镜（SEM）、布鲁诺尔-埃米特-泰勒（BET）、x射线衍射（XRD）、动态光散射（DLS）和高分辨率透射电镜（TEM）等技术对合成的α-Al2O3材料进行了分析。XRD研究发现氧化铝中存在α-Al2O3纳米晶。SEM和TEM的研究结果表明，蔗糖样品的粒径在纳米级范围内。研究发现，蔗糖浓度越高，α-Al2O3颗粒越小。α-Al2O3纳米粉体的平均粒径小于30 nm。首次将蔗糖和氧化石墨烯偶联制备纳米α-Al2O3粉体。这一发现可能为制备α-相稳定的铝纳米颗粒的新方法铺平道路，这可能在各种应用中都是有用的。

期刊介绍： The journal offers a common reference and publication source for workers engaged in research on the experimental and theoretical aspects of crystal growth and its applications, e.g. in devices. Experimental and theoretical contributions are published in the following fields: theory of nucleation and growth, molecular kinetics and transport phenomena, crystallization in viscous media such as polymers and glasses; crystal growth of metals, minerals, semiconductors, superconductors, magnetics, inorganic, organic and biological substances in bulk or as thin films; molecular beam epitaxy, chemical vapor deposition, growth of III-V and II-VI and other semiconductors; characterization of single crystals by physical and chemical methods; apparatus, instrumentation and techniques for crystal growth, and purification methods; multilayer heterostructures and their characterisation with an emphasis on crystal growth and epitaxial aspects of electronic materials. A special feature of the journal is the periodic inclusion of proceedings of symposia and conferences on relevant aspects of crystal growth.
