%X Photocatalytic oxidation using semiconductor nanoparticles is an efficient, eco-friendly, and cost-effective process for the removal of organic pollutants, such as dyes, pesticides, phenols, and their derivatives in water. In the present study, nanosize Ag每N每P-tridoped titanium(IV) oxide (TiO2) was prepared by using sol每gel-synthesized Ag-doped TiO2 and soybean (Glycine max) or chickpea (Cicer arietinum) seeds as nonmetallic bioprecursors. As-synthesized photocatalysts were characterized using X-ray diffraction, Fourier transform infrared, and ultra violet (UV)每visible spectroscopic techniques. Average crystallite size of the studied photocatalysts was within 39每46 nm. Whereas doped Ag in TiO2 minimized the photogenerated electron每hole recombination, doped N and P extended its photoabsorption edge to visible region. Tridoping of Ag, N, and P in TiO2 exhibited synergetic effect toward enhancing its photocatalytic degradation of 4-nitrophenol (4-NP), separately, under UV and visible irradiations. At three hours, degradations of 4-NP over Ag每N每P-tridoped TiO2 under UV and visible radiations were 73.8 and 98.1%, respectively
