Optimization of the selective effect of zeolite in the synthesis of Cu2O Nanoparticles

This is the authors' abstract. We don't add key points for this paper.

In this study, we exhibit a novel method for synthesizing Cu 2 O nanoparticles by employing ion exchange within the synthetic nanozeolite 4A matrix. The nanoparticles showed a consistent particle size, predominantly around 6 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 cm − 1 was observed in the FTIR spectrum, potentially indicating an aspect of zeolite downsizing related to symmetric stretching of the Si-O bond post-milling. Furthermore, a distinctive band corresponding to Cu(I)-O stretching vibrations was identified around 600 cm − 1 . Additionally, optical absorption analyses in the UV-Vis spectrum revealed two characteristic bands attributable to Cu 2 O nanoparticles, positioned at 370 nm and 470 nm, respectively. These findings lead to advancements in resource use and promote sustainable and environmentally friendly production practices.
