gravimetric analysis and vibrating sample magnetometer measurements. The catalytic behavior of the prepared nanohybrid as an efficient catalyst was successfully probed in the oxidation of sulfides, oxidative coupling of thiols and synthesis of 5-substituted 1H-tetrazoles. This method was found to have significant advantages, including high yield, green reaction conditions, short reaction time, easy separation
摘要 在本研究中,通过将镍固定在有机改性磁铁矿纳米颗粒的表面上,可以轻松制备可磁回收的催化剂。所制备的纳米结构的表征通过多种物理化学技术进行,例如傅立叶变换红外光谱,扫描电子显微镜,透射电子显微镜,能量色散X射线光谱,电感耦合等离子体发射光谱,X射线衍射,热重量分析分析和振动样品磁力计测量。在硫化物的氧化,硫醇的氧化偶联和5-取代的1H-四唑的合成中成功地探索了制备的纳米杂化物作为高效催化剂的催化行为。发现该方法具有明显的优势,包括高产量, 图形概要
