In this research, initially, modified surface multiwall carbon nanotubes clinoptilolite with Fe2O3 were synthesized. Then, genuinely eco-friendly, low-cost magnetic nanocomposite and fast approach for synthesizing diverse chromeno[4,3-b]chromene-6,8-dione derivatives in the presence of synthetic functionalized Fe2O3@CNT/COOH as novel heterogeneous and reusable Nanocatalyst was developed [1-2]. This green procedure encompasses multiple advantages, including excellent product yields, simple workup, short reaction times, high catalytic activity, and reusability of the Nanocatalyst. The structure of this synthetic Nanocatalyst is fully characterized with different techniques, including FT-IR, XRD, SEM, EDS, BET, and TGA analyses.
