Clay minerals and their derivatives are valued for unique, low-dimensional nanostructures. It is imperative to explore the characteristics of nanoclay-based matrix materials green synthesis functional composites. This study reveals defect-induced semiconductor-like optical properties kaolinite clay-derived silica nanosheets (SiNSs) employs SiNSs as a sustainable support photoinduced reducing agent photochemical supported metal nanoparticles (NPs). Results show that feature defects UV absorption ability, band gap 2.99 eV, higher photogenerated carrier separation efficiency than fumed nanosilica. Consequently, photoexcited electrons under irradiation efficiently reduce Ag/Cu-amine precursors produce SiNS-supported Ag-only AgCu-alloy NPs. Furthermore, impact intensity on Ag/Cu ratio composition alloy NPs due metal–support interaction alloying effect clarified. The optimal AgCu/SiNS-5 composite consisting Ag0.35Cu0.65 (∼12 nm) exhibits superior catalytic activity p-nitrophenol reduction within 40 s with turnover frequency 4.36 min–1 owing high adsorption reactivity interfacial active sites, multiple electron transport pathways enabled by Ag0/Cu+/Cu0/(AgCu)0. work indicates great potential SiNS's in catalysts, emphasizing key roles catalysis.
