Preparation and nitrogen-doping of three-dimensionally ordered macroporous TiO2 with enhanced photocatalytic activity

Green Synthesis of High Temperature Stable Anatase Titanium Dioxide Nanoparticles Using Gum Kondagogu: Characterization and Solar Driven Photocatalytic Degradation of Organic Dye

“…These values correspond to (004), (200), (105), (211), (204), (116), (220), (215) and (224) crystallographic planes of anatase, respectively (JCPDS No. 01-071-1166), thus confirming the formation of TiO 2 nanoparticles in the anatase phase [29]. The average crystallite size of the NPs [i.e., the mean size of the ordered (crystalline) domains, which may be smaller or equal to the grain size] was calculated using the Scherrer formula [ d = 0.89λ/βcos θ ] to be 12.58 nm.…”

A facile one-step synthesis of three-dimensionally ordered macroporous N-doped TiO2 with ethanediamine as the nitrogen source

“…Moreover, the interconnected macroporous network might facilitate mass transfer and lead to easy accessibility of active sites for the reactant molecules. 44 In the photoreaction, the electrons existing on the wall surface would be collected by the adsorbed O 2 to generate superoxide (O 2 c À H 2 O 2 ). Alternatively, the two active species might produce a chemical reaction with each other to generate hydroxyl radicals (cOH) for reacting with RhB molecules and oxidizing water molecules.…”

Effects of pore size on the photocatalytic activity of mesoporous TiO2 prepared by a sol–gel process

“…Mesoporous TiO 2 composed of nanoparticles may have abundant active sites which are of great benefits for photocatalysis. Recently, it is reported that hierarchically macro-/mesostructured titania structure with open and accessible pores shows enhanced photocatalytic activity [14,15]. It suggests the accessibility of active sites in a photocatalyst is also very important.…”
