Abstract
This study presents a novel method for synthesizing Cu2O nanoparticles by employing ion exchange within a modified nanozeolite 4A matrix. The nanoparticles had a consistent particle size, predominantly around 6[Formula: see text]nm, with a narrow distribution. Nanosizing of the zeolite was achieved through high-energy milling treatments, thereby enhancing the surface-to-volume ratio. A band close to 700[Formula: see text]cm[Formula: see text] was observed in the FTIR spectrum, potentially indicating that zeolite downsizing was related to symmetric stretching of the Si–O bond postmilling. Furthermore, a distinctive band corresponding to Cu(I)–O stretching vibrations was identified at approximately 600[Formula: see text]cm[Formula: see text]. Additionally, optical absorption analyses of the UV-Vis spectrum revealed two characteristic bands attributable to Cu2O nanoparticles at 370[Formula: see text]nm and 470[Formula: see text]nm. These findings have led to advancements in resource use and promoted sustainable and environmentally friendly production practices.
