Photocatalytic activity of anatase-brookite TiO2 nanoparticles synthesized by sol gel method at low temperature

Chitosan-Mediated Coupling of MgFe2O4–TiO2 Nanocomposites for Efficient Methylene Blue Photodegradation

“…At 500 °C, the polymer medium for loading metal oxide was thermally degraded; however, the agglomeration that reduces the XRD intensities derived from the as-mentioned thermal sintering process still occurs. Interestingly, within 600–900 °C, the highly clarified intensities of the XRD pattern suggest that the optimal formation of ferrite oxide-coupling material and enhanced thermal sintering process driven by temperature have resulted in a spreading larger crystal to the desired dimension and impressive crystallographic phase. − …”

Cellulose-templated Bi2SiO5nanorods with enhanced UV/vis light utilization efficiency for high-performance photocatalytic degradation of organic contaminants

“…Comparisons of photocatalytic efficiencies of the present catalyst with those of other previously reported semiconductor catalysts are shown in Fig. 6f and Table S3,† including Bi 2 S 3 /Bi 4 O 7 , 46 C–WO 3 , 47 Fe-g-C 3 N 4 , 48 Au–SiO 2 /g-C 3 N 4 , 49 p -ZnO, 50 Fe 3 O 4 /SiO 2 /TiO 2 , 51 TiO 2 /WO 3 − x , 52 TiO 2 /ZnO-g-C 3 N 4 , 53 ZnO–SiO 2 , 54 TiO 2 , 55 B/W–TiO 2 , 56 ZnO/G/C 3 N 4 , 57 and WO 3 /g-C 3 N 4 . 58 The comparison results showed that the CBSO catalyst in this study showed an excellent RhB degradation efficiency, which was much higher than that of the other reported photocatalysts within the same reaction period.…”

Bismuth tungstate Bi2WO6: a review on structural, photophysical and photocatalytic properties

“…However, titanium dioxide (TiO 2 ) has emerged as a popular choice for environmental remediation due to its chemical stability, low cost, and strong oxidizing power, as documented in studies conducted by ref. 11–14. Nonetheless, TiO 2 has certain limitations, such as its high gap ( E g = 3.2 eV), which restricts UV radiation absorption to only 4% of the solar spectral band, or 387.5 nm, as observed in studies by ref.…”
