| Description |
Copper nanoparticles (CuNPs) confined in hollow silicalite-1 powders were synthesized by a selective ``desilication-recrystallization'' method using tetraethlyorthosilicate (TEOS), tetrapropylammonium hydroxide (TPAOH) and cupric chloride (CuCl2) as precursors. The synthesized product was characterized by XRD, Raman, XPS, FESEM, TEM and N-2 adsorption-desorption studies. The presence of CuNPs of size 10-40 nm in the hollow silicalite-1 was confirmed by TEM. The BET surface area of the powders was 247 m(2) g (1) composed of micropores and mesopores. The prepared CuNPs confined in hollow silicalite-1 showed excellent catalytic performance for the reduction of 4-nitrophenol (4-NP) to 4-aminophenol (4-AP) with apparent rate constant and activity parameter values of 5.6 x 10(-3) s(-1) and 44.09 s(-1) g(-1), respectively for 1 mg of catalyst.
