چکیده	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, inductively coupled plasma optical emission (ICP‐OES) and energy‐dispersive X‐ray spectroscopies, and scanning and transmission electron microscopies. Finally, this catalyst was applied as a moisture‐ and air‐stable heterogeneous material for the synthesis of 5‐substituted 1H–tetrazole derivatives. The leaching of palladium and heterogeneity of the catalyst were studied using hot filtration and ICP‐OES. This catalyst demonstrated remarkable recyclability. The novelty of this work is that it represents the first time an amino acid has been grafted on boehmite nanoparticles.
