Synergistic effect of Cu adsorption on the enhanced photocatalytic degradation of bisphenol A by TiO2/titanate nanotubes composites

Heterostructured ZnFe2O4/TiO2 nanocomposites with a highly recyclable visible-light-response for bisphenol A degradation

“…The slight decrease in k obs is attributed to the accumulation of inter mediates aer photocatalytic degradation of BPA and loss of the trace amount of photocatalyst during separation. [44][45][46][47] In addition, the released aqueous concentrations of Zn and Fe aer 10 cycles are 32 and 21 mg L À1 , respectively, which are far lower than the standards of Zn (5 mg L À1 ) and Fe (0.3 mg L À1 ) in drinking water. These results indicate that ZnFe 2 O 4 -TiO 2 is an environmentally friendly and stable photocatalyst, which can maintain the highly recyclable photoactivity under visible light irradiation conditions.…”

Simultaneous Recovery of Display Panel Waste Glass and Wastewater Boron by Chemical Oxo-precipitation with Fluidized-Bed Heterogeneous Crystallization

“…This result clearly indicates the nonporous nature of silica sand, and the hysteresis loop at a high P / P 0 range is mainly attributed to the interparticle voids of silica sand. In contrast to silica sand materials, the adsorption–desorption isotherm of MAS material follows a type IV physisorption isotherm with an H3 hysteresis loop in the P / P 0 range of 0.4–0.98, which is mainly attributed to the capillary condensation in mesoporous structures . Moreover, the pore size distribution of MAS exhibits a sharp peak at 3.9 nm and then follows a broad pore size distribution in the mesoporous region (2–50 nm).…”

The peak of 3.9 m is mainly attributed to the hierarchically pore structure of nanoparticles, while the broad distribution is from the voids of the interparticles of MAS.…”

One-Pot Synthesis of Titanate Nanotubes Decorated with Anatase Nanoparticles Using a Microwave-Assisted Hydrothermal Reaction

“…A vast number of structure-property relationship studies led scientists not only to apply these materials in various fields but also to understand the basic mechanism of the phase transformation between crystalline phases of titania and titanates, as well as to the possibility to generate new functional materials with tailored properties [4]. Formation of a TiO 2 -(anatase-) trititanate heterostructure is one example, which has been a hot topic recently because of its increased efficiency in photocatalysis and photodegradation [5]. These properties have been associated with different structural and electronic properties, such as the band gap and the surface area [5,6].…”

These properties have been associated with different structural and electronic properties, such as the band gap and the surface area [5,6]. TiO 2 -(anatase-) trititanate heterostructures are easily interconverted by low-energy-requiring pathways as predicted by calculations because of the structural similarity between trititanate and TiO 2 (anatase) [7].…”
