Titanium dioxide/magnetic metal-organic framework preparation for organic pollutants removal from water under visible light

Enhanced photocatalytic activity of TiO2/UiO-67 under visible-light for aflatoxin B1 degradation

“…Besides, the peak of Zr–O stretching vibration at 768 cm −1 , 670 cm −1 are not obvious in T-10%U, which may be attributed to its replacement by a wide absorption peak of TiO 2 appearing at the range of 500–800 cm −1 . 31 From all observations mentioned above, it can be concluded that the T-10%U is effectively composited by UiO-67 and TiO 2 .…”

“…TiO 2 /UiO-67 photocatalyst (named as T- X U, where X is the mass ration of the UiO-67 ( X = 2.5%, 10%, 10%, 30%) with respect to tetrabutyl titanate) was synthesized by a simple in situ solvothermal method according to previous references. 31 In the prepared process, 0.2 mL tetrabutyl titanate, 30 mL ethanol and 3 mL acetic acid were mixed to form transparent homogeneous solutions. Then different mass ratio UiO-67 was dispersed to the above solutions and stirred for 30 min.…”

“… 30 Zhang et al synthesized TiO 2 /mag-101(Cr) combined the advantages of TiO 2 , MOFs and Fe 3 O 4 to improve photocatalysis degradation efficiency of organic pollutants. 31 In recent years, UiO-67, one of the Zr-MOFs, has large surface area, good photocatalysis activity and lower bandgap (3.14 eV), 32 which has better light response than TiO 2 . 33 Therefore, designing TiO 2 /UiO-67 heterostructures is a feasible approach for improving the photocatalytic activities of TiO 2 .…”

A Review of Metal–Organic Framework‐Based Compounds for Environmental Applications

“…In recent years, MOF-based compounds have been widely applied in many research fields due to their good optical performance, huge surface area, high catalytic performance, etc. [384,385] In this part, we summarize the MOF-based compounds for various environmental applications, including organic pollutant removal, [386,387] toxic and hazardous gas capture, [388,389] heavy metal ion detection, [390,391] gas separation, [392,393] water harvesting, [394,395] air purification, [396,397] and CO 2 RR.

Advances in the Application of Nanocatalysts in Photocatalytic Processes for the Treatment of Food Dyes: A Review

“…Meanwhile, Zhang et al [155] synthesized a catalyst consisting of TiO 2 /mag-MIL-101 (Cr) nanoparticles under visible light. The magnetic property of this TiO 2 -loaded composite enhanced its adsorption and photocatalytic efficiency with a forbidden band value of 1.61 eV.…”
