摘要: The visible-light-driven photocatalytic degradation of Bisphenol A (BPA) was investigated using the binary composite alkaline treated g-C3N4 (HT-g-C3N4) deposited over commercial TiO2 (Evonik Degussa GmbH, Essen, Germany). existence and contribution both g-C3N4/HT-g-C3N4 in confirmed through various analytical techniques including powder X-ray diffraction (XRD), high-resolution transmission electron microscopy (HRTEM), field emission scanning (FESEM), Fourier transform infrared spectroscopy (FTIR), photoelectron (XPS), ultraviolet-visible diffuse reflectance spectra (UV-vis-DRS), photoluminescence (PL) analysis. results showed that titania exhibited pure rutile anatase phases. morphological analysis indicated spongy “morel-like” structure turned to nanotube form after hydrothermal treatment thereby decreased specific surface area HT-g-C3N4. low HT-g-C3N4 dominates its promising optical property effective charge transfer, resulting a deprived efficiency BPA two times lower than g-C3N4. HT-g-C3N4/TiO2 excellent with 2.16 higher enhanced activity mainly due band gap heterojunction interface, favorable area, good separation.
