摘要: Abstract Here, we report the synthesis of bare Ag2S nanoparticles (NPs), SiO2 and TiO2 capped nanocomposites (NCs) by a simple one-pot hydrothermal method. The NCs, prepared treatment, could be maintained uniformly distributed on surface precursors. physicochemical properties photocatalysts were characterized XRD, SEM, TEM, TGA, FTIR, zeta potential, PL, UV–vis DRS. synthesized NPs, NCs showed strong spectral absorption capabilities in visible regions. diameter are observed to range 10–30 nm. Consequently, they exhibited prominent photocatalytic behavior samples for degradation Eosin Y (EY) Safranin O (SO) dyes under sunlight irradiation. It shows that has an excellent activity EY (96.41%) SO (91.38%) than NPs NCs. extent was confirmed performing TOC analysis, over 85% removal achieved. followed pseudo-first order kinetics. composite materials present which highly promising environmental clean-up applications.
