New water based EPD thin BiVO4 film: Effective photocatalytic degradation of Amoxicillin antibiotic

An Exploration of the Four‐Decade‐Long History of Photocatalytic Water Treatment: Analysis of Key Advancements, Underlying Relationships, and Failures along the Way

“…[103] Despite the advances above, researchers have abandoned TiO 2 -based treatments, and there has been increasing attention on exploring new photocatalysts other than TiO 2 and ZnO. [104] The non-TiO 2 -based photocatalysts are categorized as1) metal oxides such as ZnO and BiVO 4 ; [105] 2) metal sulfides, such as CdS (high occurrence), Cu 7 S 4 , ZnS, Bi 2 S 3 , PdS, [106] and NaBiS 2 ; [107] 3) bismuth metalates, such as Bi 2 WO 6 ; [108] 4) graphene-based photocatalysts, such as graphene-TiO 2 , under solar light irradiation; [109] and 5) carbon nitride photocatalysts, such as TiO 2 -based composites loaded with g-C 3 N 4 . [47] Hence, discovering new potent photocatalysts and lacking convincing technical applications have rendered TiO 2 irrelevant to research.…”

Ag2O@UiO-66 new thin film as p–n heterojunction: permanent photoreduction of hexavalent Cr

“…Previous studies have reported the p-n junction of Ag 2 O and UiO-66. 34,35 Following our previous studies on the design and synthesis of new photocatalysts, 10,[36][37][38][39] in this work, for the rst time, a Ag 2 O@UiO-66 thin-lm was deposited on a steel mesh by electrophoretic deposition. This resulted in a metal-organic framework thin-lm composite which we used as an efficient visible light active photocatalyst for the reduction of toxic chromium(VI) to non-toxic chromium(III) in aqueous solution.…”

In situ synthesis of holey g-C3N4 nanosheets decorated by hydroxyapatite nanospheres as efficient visible light photocatalyst

“…7,8 Recently, because of diminishing photocatalytic activities, researchers have switched their routes to the synthesis of nanocomposites or immobilized forms on supports. 9,[11][12][13] Immobilized photocatalysts could improve charge separation and enhance degradation performance. Considering this effective remediation method, graphitic carbon nitride (g-C 3 N 4 ) was introduced in 2009 as an excellent photocatalyst with eco-friendly characteristics, nontoxicity, thermal and chemical stability, low-cost preparation, and easy cut-rate fabrication.…”
