In this study, natural surface-modified nano-clinoptilolite, NCP@SiO۳Pr(CH۲)۶N۴, 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.
