Nickel‐anchored curcumin‐functionalized boehmite nanoparticles (BNPs@Cur‐Ni) as a robust and versatile nanocatalyst was synthesized and well‐characterized by using Fourier transform infrared (FT‐IR), transmission electron microscopy (TEM), scanning electron microscopy (SEM), energy dispersive X‐ray (EDX), X‐ray mapping, thermogravimetric analysis (TGA), differential thermal analysis (DTA), Brunauer–Emmett–Teller (BET), X‐ray diffraction (XRD), and inductively coupled plasma optical emission spectroscopy (ICP‐OES). The synthesis of 5‐substituted 1H‐tetrazoles and the oxidation of sulfides were conducted by BNPs@Cur‐Ni with excellent turnover number (TON) and turnover frequency (TOF) outcomes. Also, the catalyst was reused for several sequential runs without Ni leaching or decreasing in reaction yield. Utilizing the curcumin and boehmite with a natural source as well as poly(ethylene glycol) (PEG) as a solvent in this simple protocol can be based on green chemistry rules.

勃姆石纳米颗粒/镍姜黄素作为一种强大而高效的绿色纳米催化剂，可合成5-取代的1H-四唑和硫化物的氧化

通过傅立叶变换红外光谱（FT-IR），透射电子显微镜（TEM），扫描电子显微镜（SEM）合成了镍锚固姜黄素官能化勃姆石纳米颗粒（BNPs @ Cur‐Ni），它是一种功能强大且用途广泛的纳米催化剂。 ），能量色散X射线（EDX），X射线映射，热重分析（TGA），差热分析（​​DTA），Brunauer-Emmett-Teller（BET），X射线衍射（XRD）和感应耦合等离子体光学发射光谱（ICP-OES）。5取代1 H的合成BNPs @ Cur-Ni进行了四唑和硫化物的氧化，具有优异的周转率（TON）和周转率（TOF）。而且，该催化剂可重复使用几次，而不会发生镍的浸出或反应产率的降低。在此简单协议中，将姜黄素和勃姆石与天然来源以及聚乙二醇（PEG）用作溶剂可以基于绿色化学规则。
