Photocatalytic antifouling PVDF ultrafiltration membranes based on synergy of graphene oxide and TiO2 for water treatment

Preparation and Performance of Visible‐Light‐Driven Bi2O3/ZnS Heterojunction Functionalized Porous CA Membranes for Effective Degradation of Rhodamine B

“…For Bi 2 O 3 /ZnS‐CA membranes, the amelioration in cross‐sectional structure could be noted clearly from the SEM images. This phenomenon could indicate the stronger hydrophilicity of Bi 2 O 3 /ZnS than that of Bi 2 O 3 and ZnS particles . These results were also consistent with the porosity and pore size data of membranes in Table .…”

“…The surface hydrophilicity of the photocatalytic membranes was an important factor in measuring the permeability, which can be analyzed by the sessile drop technique. In general, smaller water contact angle means higher hydrophilicity . As shown in Figure , the original CA membranes presented the mean water contact angle of 72°, which was lower than Bi 2 O 3 ‐CA (81°) and ZnS‐CA (79°) membranes.…”

Ag modified g-C3N4 composite entrapped PES UF membrane with visible-light-driven photocatalytic antifouling performance

“…Flux recovery ratio (FRR) is an important parameter to characterize the antifouling property of membranes and it is generally believed that the higher FRR means better antifouling performance. 32,33 As shown in Fig. 10, the FRR of M0 was as low as 41% and all composite membranes had higher FRR than pristine PES membrane (without light).…”

A review on organic–inorganic hybrid nanocomposite membranes: a versatile tool to overcome the barriers of forward osmosis

“…149,150 As an acknowledged photocatalytic material, TiO 2 has been extensively used in disinfection and decomposition applications; these characteristics also make TiO 2 a promising anti-fouling modier. 25,151 Moreover, due to the chemical stability, controllable morphology, surface properties, photocatalytic function and antifouling performance of TiO 2 nanoparticles, they are useful in membrane processes. [152][153][154][155][156] Numerous studies regarding the introduction of TiO 2 nanoparticles into membranes have conrmed its viability and effectiveness, leading not only to enhanced hydrophilicity and water permeability, but also to sterilization and antibiofouling abilities.…”

Amini's group 4 introduced TiO 2 nanoparticles into a polysulfone support layer to reduce the structural parameter and alleviate the ICP of FO membranes.…”
