Recent advancements in supporting materials for immobilised photocatalytic applications in waste water treatment

TiO2/rGO/CuS Nanocomposites for Efficient Photocatalytic Degradation of Rhodamine‐B Dye

“…There are several methods developed to purify the contaminated water namely, filtration, coagulation, ion exchange, adsorption, biodegradation, chemical oxidation and photocatalysis . Among these approaches the photocatalysis is simple, cost effective and further solar energy can be harvested to degrade effluents in large scale, hence it is the most effective solution to environmental pollution and the energy crisis …”

Reactive Magnetron Sputter Deposition of Bismuth Tungstate Coatings for Water Treatment Applications under Natural Sunlight

“…Bismuth tungstate coatings are often described as efficient visible light-activated photocatalytic materials [15], however, they are usually produced by chemical methods, e.g., hydrothermal methods [13,14] or electrospinning [22]. Use of photocatalyst-coated particulates is frequently reported for water treatment applications, however, chemical methods are typically used for the coating's deposition [23][24][25]. The establishment of a reactive sputter deposition method as a technique for the production of bismuth complex oxides [15,21,26] allows some limitations of these chemical deposition methods, such as the use of hazardous precursors or byproduct formation, to be overcome and provides a simple, yet efficient and readily up-scalable deposition technique.…”

Removal of methylene blue from aqueous solution by electrophoretically deposited titania‐halloysite nanotubes coatings

“…However, the practical applications of the suspensions are limited due to the difficulty in the filtration and reuse of titania nanoparticles. The filtration step can be eliminated by immobilizing the titania nanoparticles on an appropriate supporting material . Several methods have been used to immobilize photocatalyst titania nanoparticles on the supporting materials such as sol–gel, chemical vapor deposition (CVD), thermal spray, and spray pyrolysis .…”

“…The filtration step can be eliminated by immobilizing the titania nanoparticles on an appropriate supporting material. 66 Several methods have been used to immobilize photocatalyst titania nanoparticles on the supporting materials such as solgel, 67,68 chemical vapor deposition (CVD), 69 thermal spray, 70,71 and spray pyrolysis. 72 Electrophoretic deposition (EPD) is a colloidal processing method which has been widely used to deposit ceramic particulate layers on metallic substrates.…”
