Abstract
A method of making a zeolite USY/carboxylated cellulose nanocomposite (CCN) includes preparation of carboxylated cellulose nanofibers (CCNFs) by grinding date-palm tree leaflets into fine particles, oxidizing with HNOand NaNOat 80-90° C. for 8-12 hours, quenching, washing, and centrifuging to obtain the CCNFs. The method further includes preparation of zeolite USY nanoparticles by wet ball milling zeolite USY, washing, centrifuging, drying at 60-100° C. for 60-120 minutes, and crushing to obtain the zeolite USY nanoparticles. The method further includes the synthesis of the zeolite USY/carboxylated cellulose nanocomposite by mixing zeolite USY nanoparticles with CCNFs and triethylamine, autoclaving at 60-80° C. for 15-30 hours, cooling, centrifuging, and drying at 50-80° C. for 15-30 hours to form the zeolite USY/CCN.
