In this study, a high-performance heterogeneous nanocatalyst was synthesized by anchoring silver nanoparticles onto SBA-15 mesoporoussilica modified with ionic liquids. The material was comprehensively analyzed through several analytical instruments, including X-ray diffraction (XRD), field emission scanning electron microscopy (FE-SEM), energy dispersive X-ray spectroscopy (EDX), Fourier transform infrared spectroscopy (FT-IR), transmission electron microscopy (TEM), wavelength dispersive Xray spectroscopy (WDX), inductively coupled plasma optical emission spectroscopy (ICP-OES), and Brunauer–Emmett–Teller (BET) surface area analysis. These analyses confirmed the uniform dispersion and strong interaction of silver nanoparticles with the functionalized SBA-15 support. The catalytic efficiency of the synthesized material was tested through the reduction of 4- nitrophenol to 4-aminophenol under mild aqueous conditions. The catalytic enhancement is due to the synergy between ionic liquid functionalities and silver nanoparticles, which facilitates efficient ele
