Degradation of sulfamethazine using sludge-derived photocatalysts from dyeing industry and livestock farm: preparation and mechanism

Enhanced Solar‐Photo(Electro)catalysis of Microwave‐Hydrothermal Synthesized BiVO4, ms‐BiVO4/Reduced Graphene Oxide/Ag3PO4 Nanohybrid: Crystalline Phase‐Dependent Interfacial Charge Carrier Dynamics

“…The light irradiated on RhB could excite electrons from the LUMO of RhB*, and their generated electrons are captured by CB of the ms ‐BiVO 4 /RGO/Ag 3 PO 4 composite system; consequently, the dissolved O 2 in water gives •O 2 − to degrade RhB. [ 72–75 ] The incorporation of reduced GO could considerably enhance photogenerated charge carrier separation and transfer ability with effective inhibition of the recombination of photoinduced electron and hole pairs at their interface of Ag 3 PO 4 and ms ‐BiVO 4 , which improves the photocatalytic efficiency for RhB degradation. The free radical tests with various hole scavengers are depicted in Figure S17a, Supporting Information.…”

Fabrication of two 2D Cu-based coordination polymers via a secondary ligand adjustment and a derived Cu/Cu2O heterojunction for an enhanced dye removal capacity

“…Cu-based materials not only possess dye adsorption properties, but also can be used as catalysts for the photocatalytic degradation of dyes. 8,9 The UV-vis spectra of the title materials are shown in Fig. 8 and S14–S19 †.…”

“…7 They have routinely been prepared by pyrolysis followed by physical or chemical activation of the organic precursors. 8 Although the resultant activated porous carbons possess a high surface area, their structures are disordered with a broad pore size distribution which thereby limits their utilization in dealing with molecular discrimination. Meanwhile, most Cu( i )-based materials are considered as p-type semiconductors, which have received much attention in recent years because of their excellent photocatalytic activity.…”

Ag–Cu Embedded SDS Nanoparticles for Efficient Removal of Toxic Organic Dyes from Water Medium

“…Numerous domestic and industrial activities, such as cleaning, cooking, agriculture, and product development, require water . Anthropogenic actions have depreciated freshwater bodies and therefore the uncontrolled release of effluent and unmaintainable exploitation of water is presently the “hottest subject” for water management . Since industrialization and urbanization is rising uncontrollably, the demand of water is increasing promptly.…”

“…1 Anthropogenic actions have depreciated freshwater bodies 2 and therefore the uncontrolled release of effluent and unmaintainable exploitation of water is presently the "hottest subject" for water management. 3 Since industrialization and urbanization is rising uncontrollably, the demand of water is increasing promptly. Consequently, the limited capitals of the water should be used vigilantly in order to meet the rising demand of it in different sectors.…”
