Boehmite nanoparticles are aluminium oxide hydroxide (γ‐AlOOH) particles, which were prepared using a simple and inexpensive procedure in water at room temperature and further modified using arginine. Subsequently palladium particles were immobilized on their surface to prepare Pd‐Arg@boehmite. This novel nanostructured compound was fully characterized using thermogravimetric analysis, X‐ray diffraction
勃姆石纳米颗粒是氢氧化铝(γ-AlOOH)颗粒,使用简单且廉价的方法在室温下于水中制备,然后使用精氨酸进一步改性。随后,将钯颗粒固定在其表面上以制备Pd-Arg @ boehmite。通过热重分析,X射线衍射,电感耦合等离子体光学发射(ICP-OES)和能量色散X射线光谱学以及扫描和透射电子显微镜学对这种新型纳米结构化合物进行了全面表征。最后,该催化剂被用作湿气和空气稳定的非均相材料,用于合成5取代的1 H–四唑衍生物。使用热过滤和ICP-OES研究了钯的浸出和催化剂的非均质性。该催化剂显示出显着的可回收性。这项工作的新颖之处在于,它是首次将氨基酸接枝到勃姆石纳米颗粒上。
