synthesis and characterization of the aminated nano-zeolite: a green heterogeneous nanocatalyst for the synthesis of valuable organic compounds

In this study, natural surface-modified nano-clinoptilolite, ncp@sio3pr(ch2)6n4, was synthesized and fully characterized using various analytical techniques, including ft-ir, xrd, sem, eds, tem, and tg-dta analyses. additionally, this aminated nanocatalyst was evaluated for the effective synthesis of α,β-unsaturated carbonyl compounds containing valuable substances such as barbituric acid moiety under solvent-free conditions. this catalyst obtained desired products with excellent yields, high purity, and short reaction times. furthermore, the synthetic, non-toxic heterogeneous nanocatalyst is easily recycled and can be reused several times.
