Preparation, characterization and photocatalytic application of TiO2–graphene photocatalyst under visible light irradiation

Enhanced sunlight-driven photocatalytic activity of graphene oxide/Bi2WO6 nanoplates by silicon modification

“…The band at 1100 cm À 1 is assigned to the Si-O vibration in silicates [26], further confirming the existence of Bi 12 SiO 20 . In addition, the bands peaking at 1640 cm À 1 and in the range of 3000-3500 cm À 1 indicate the existence of CQO [27] and -OH groups in GO [28]. After photocatalytic test, the collected samples display nearly unchanged adsorption peaks, suggesting a good photocatalytic stability of Si-GO/BWO nanoplates.…”

Synthesis of porous g-C3N4/La and enhanced photocatalytic activity for the degradation of phenol under visible light irradiation

“…TiO 2 has been the most widely used photocatalytic material for its chemical inertness, non-toxicity, low cost and high photocatalytic efficiency [2]. Nevertheless, TiO 2 suffers from two main problems including wide band gap and low quantum efficiency, and therefore it performs ineffectively in the practical applications [3].…”

Optimal TiO2–Graphene Oxide Nanocomposite for Photocatalytic Activity under Sunlight Condition: Synthesis, Characterization, and Kinetics

“…To examine the effect of GO content on the MB degradation mechanism, an appropriate model is required to analyze the concentration data. Normally, the photocatalytic activities of TiO 2 and TGO‐X nanocomposites were evaluated by the first‐order kinetic model as a follows :…”
