Enhanced the photocatalytic degradation of titanium dioxide nanoparticles synthesized by different plant extracts for wastewater treatment

Sustainable approaches towards green synthesis of TiO2 nanomaterials and their applications in photocatalysis‐mediated sensing to monitor environmental pollution

“…The obtained result showed that TiO 2 NPs based on a green synthesis route was able to remove organic pollutants from wastewater. [ 31 ] In continuation, Goutam and co‐workers synthesized TiO 2 NPs using Jatropha curcas L. (biodiesel plant) leaf extracts to study its permeability for tannery wastewater. [ 32 ] Furthermore, synthesized TiO 2 NPs were utilized to remove chemical oxygen demand (COD) as well as chromium (Cr) simultaneously from secondary treated tannery wastewater.…”

“…[30] Recently, Mousa and colleagues reported photocatalytic effectbased degradation of methyl orange (dye) as a water contaminant. [31] This study included three diverse aqueous extracts derived from pomegranate, Beta vulgaris and Seder that acted as reducing agents to produce TiO 2 NPs. The obtained result showed that TiO 2 NPs based on a green synthesis route was able to remove organic pollutants from wastewater.…”

Fabrication of a zinc oxide/alginate (ZnO/Alg) bionanocomposite for enhanced dye degradation and its optimization study

“…which are intensively used due to its strong absorption in the UV and visible region. [13][14][15][16][17] So far, some of the materials used as photocatalysts to remove various pollutants are TiO 2 and ZnO and has been utilized in varied elds such as catalysis, solar energy conversion, optoelectronics, and biolabeling. [18][19][20] Many areas can benet from the eco-friendly qualities of nanoscale zinc oxide, which is affordable, non-toxic, and antibacterial.…”

“…They discovered that green-generated TiO 2 NPs had higher photocatalytic activity and efficiency in photodegrading MO in the presence of UV light than chemically synthesized TiO 2 NPs samples. 13 Another study reported on a simple method was used to prepare ZnO@SiO 2 nanomaterials for photocatalytic degradation of organic dyes methylene blue and eosin under UV light. In this study, the estimation of chemical oxygen demand (COD) for the dye solution before and after the photocatalytic reaction was found to be 97% in MB and 92% in eosin dye.…”

A type II heterojunction α-Fe2O3/g-C3N4 for the heterogeneous photo-Fenton degradation of phenol

“…Thus, constructing a composite with a suitable band energy gap is a mainstream approach to widen the light absorption region and reduce the charge recombination. [16][17][18][19][20] Graphitic carbon nitride (g-C 3 N 4 ), as a two-dimensional layered semiconductor, has drawn particular attention in photocatalysis due to its element abundance, facile preparation, great visible light activity, high thermal and outstanding chemical stabilities, and excellent electronic structure. 21 Recently, the composite photocatalysts combining a-Fe 2 O 3 and g-C 3 N 4 have been successfully fabricated and showed great performance in water splitting, 22 carbon dioxide reduction, 23 photochemical reaction, 24 and heavy metal ion reduction.…”
