In this paper, using L., a leaf-extracted, assisted microwave method (MM) was used to synthesize nickel oxide formation. We synthesized nickel oxide nanoparticles (NiO) with a crystal size in the range of 15-16 nm by a leaf-assisted microwave method (LAMM). The synthesized materials show that an X-ray diffraction (XRD) study confirmed the formation of a single phase structure exhibiting a crystallite size in the range of 15-16 nm using Scherrer's method. The nickel oxide prepared by the MM had a surface area of 60.35 m²/g, pore volume of 0.9427 cm³/g and an average pore diameter of 13.27 Å. Surface morphology was analyzed by the scanning electron microscope (SEM), X-ray photoelectron spectroscope, Brunauer-Emmett-Teller (BET) analysis, and the vibrating sample magnetometer (VSM). Catalytic activity (CA) tended toward the oxidation of styrene to benzaldehyde. The inexpensive catalyst tested is likely effective as a catalyst due to synergistic interactions between metal oxides with high dispersion. In comparison with other findings, LAMM is easy and eco-friendly. The current study obtained nanocrystalline NiO that was suitable for potential applications in catalysis. The synthesized NiO could potentially be used in therapeutic field due to their competent antibacterial activity.
在本文中，采用从树叶中提取的辅助微波法（MM）合成了氧化镍。我们通过树叶辅助微波法（LAMM）合成了晶体尺寸在15 - 16纳米范围内的氧化镍纳米颗粒（NiO）。合成材料的X射线衍射（XRD）研究表明，使用谢乐法证实形成了单相结构，其微晶尺寸在15 - 16纳米范围内。通过MM制备的氧化镍的表面积为60.35平方米/克，孔体积为0.9427立方厘米/克，平均孔径为13.27埃。通过扫描电子显微镜（SEM）、X射线光电子能谱仪、布鲁诺尔-埃米特-泰勒（BET）分析和振动样品磁强计（VSM）对表面形态进行了分析。催化活性（CA）倾向于将苯乙烯氧化为苯甲醛。由于高分散金属氧化物之间的协同相互作用，所测试的这种廉价催化剂可能是一种有效的催化剂。与其他研究结果相比，LAMM方法简便且环保。当前的研究获得了适用于催化潜在应用的纳米晶NiO。合成的NiO因其具有良好的抗菌活性，有可能用于治疗领域。
