In this work, Cu 2 S ultrasmall nanoparticles were synthesized in a zeolite 4A nanoreactor (ZA) by the ion exchange method, which consisted of two steps: (1) the ion exchange of Na + , located in ZA, for Cu + and Cu 2+ , and (2), formation of Cu 2 S nanoparticles, using Na 2 S by metathesis reaction (double displacement reaction). The molecular structure of ZA was verified by FT-IR and XRD and the formation of Cu 2 S nanoparticles in the ZA matrix by DSC, UV–Vis, Raman, TEM, and HRTEM characterizations. The results showed a non-modified molecular structure of the Z4 by synthesis of Cu 2 S nanoparticles with a size distribution of 4–8 nm.
