Energy-Efficient CuO/TiO2@GCN Cellulose Acetate-Based Membrane for Concurrent Filtration and Photodegradation of Ketoprofen in Drinking and Groundwater

“…As the weight loading of CuO/TiO 2 @GCN was increased the hydrophilic nature of modified CA films increased. The co-existence of highly hydrophilic CuO/TiO 2 @GCN surface properties contributed to an increase in the hydrophilic properties of the modified CA films [3,49].…”

“…The consequences of their hydrophobicity and propensity to foul are that their separation efficiency is reduced and so is their water flux, resulting in high electrical energy consumption (E EC ) as high pressure is required. Additionally, this leads to high running expenses and the lifespan of the membranes is significantly reduced [3]. Attempts have been made to regenerate 2 of 19 membranes, but these processes usually involve the use of harsh chemicals and/or physical and electrical processes that can damage and contaminant the membrane [4].…”

A review on the potential of photocatalysis in combatting SARS-CoV-2 in wastewater

“…The technology of photocatalysis that employs carbon-based photocatalyst has attracted much attention due to the zero risk of metal leaching into the water system and optimum natural light-harvesting capability [ [77] , [78] , [79] ]. The non-metal photocatalysts that have been developed for virus disinfection include carbon-based materials such fullerene [ 80 , 81 ] carbon nanotube [ 82 ], carbon dot [ 83 , 84 ], and graphitic carbon nitride (g-C 3 N 4 ) [ 78 , 85 , 86 ].…”

Fabrication and characterization of a TiBs@MCN cable-like photocatalyst with high photocatalytic performance under visible light irradiation

“…Many strategies have been proposed to improve the visible-light photocatalytic efficiency of TiO 2 such as ion doping materials, metal loading materials, heterojunction hybrids, and sensitization. 14–18 Among them, heterojunction formation with the use of narrow bandgap semiconductors is considered to be one of the most effective methods to address the above-described limitations of TiO 2 . 19…”
