This work focuses on the preparation of composite beads from alginate crosslinked with copper at several loading percent and also loaded with ZnNPs. Th obtained samples were applied as catalysts for the reduction of the organic polluants 4-NP, MB, OG, MO, and CR in simple and binary systems. XRD results and TEM images confirmed the presence of ZnNPs in the polymer matrix.

- The mesoporous silica MCM-41 was synthesized and modified with silver and copper for use as antibacterial/antifungal agents and catalysts to reduce various dyes like Methylene Blue and Congo Red.
- The catalysts were thoroughly characterized, revealing that calcination led to well-distributed copper oxide and silver nanoparticles, which significantly influenced their catalytic activity and efficiency in dye reduction.
- The Ag-Cu-MCM(0.05) catalyst exhibited the highest activity, especially in single-dye systems, and showed improved selectivity for Methylene Blue in binary systems, while uncalcined materials demonstrated superior antibacterial and antifungal properties due to the synergy between copper and silver species.
