A novel composite derived from a metal organic framework immobilized within electrospun nanofibrous polymers: An efficient methane adsorbent

“…While the large surface area predicted by RSM under optimal conditions could be considered as a promising sign that the synthesized Ta‐MOF can be a good candidate for CH 4 adsorption, the study of the mechanical properties of the produced MOF nanostructures is of great importance for developing a highly efficient adsorption process for trapping methane. Biocompatibility and biodegradability are critical properties of adsorbents for the development of eco‐friendly adsorption/separation processes . Most of the studied MOFs did not exhibit sufficient biocompatibility/biodegradability properties, therefore the manufacture of highly efficient MOF absorbents with such properties is still a profound challenge in the development of MOF‐based eco‐friendly adsorption processes.…”

Review of the Advancements on Polymer/Metal Oxide Hybrid Nanocomposite‐Based Adsorption Assisted Photocatalytic Materials for Dye Removal

“…Such polymer properties are essential to recycle the photocatalyst without losing its catalytic activity. [82,83] In addition, their porous structure and the presence of some functional groups also enhance surface adsorption, which makes the dye molecules easily accessible on the surface of the photocatalyst. [58,84,85] Thus, the photocatalytic dye degradation reaction by such polymer/metal oxide hybrid nanocomposite is solely sensitized by metal oxides.…”

[86] The photocatalytic degradation of congo red by barium crosslinked alginate/carboxymethyl cellulose/TiO 2 , [63] methyl orange by Polyether sulfone/TiO 2 , [82] TiO 2 /chitosan, [86] and zein/ poly (propylene carbonate)/TiO 2 (zein/PPC/TiO 2 ), [87] malachite green by polymeric poly (dl-lactide-co-glycolide)-zinc oxide nanocomposite (PLGA-ZnO-N C ), [84] Methylene blue by ZnOpoly (methyl methacrylate) (ZnO-PMMA), [88] acid yellow and acid blue by zein/TiO 2 , [83] neutral red and crystal violet by polyacrylamide/calcium alginate/TiO 2 (PAM/CA/TiO 2 ), [85] acid red 14 (AR14) by chitosan/polyvinyl alcohol/TiO 2 (CS/PVA/ TiO 2 ), [58] Rhodamine B by chitosan/CdO/NiO, [29] methylene blue by poly(acryl nitrile)/ZnO(PAN/ZnO), [53] and acid black 1 by gelatin assisted TiO 2 /BiOI (g-TiO 2 /BiOI), [89] are among polymer/ metal oxide hybrid composites which prevent nanoparticle agglomeration, improve stability and recyclability of the catalyst and increase adsorption of dye molecules to the catalyst surface.…”

Trypan blue removal from water with zein sorbents and laccase

“…Different sorbents have been proposed for the removal of dyes from water, including sulfuric acid treated sawdust [ 18 ], apple pomace and wheat straw [ 19 ], immobilized fungi [ 20 ], activated carbon, bagasse, husk, date pits, corncob, pinewood and pith [ 21 ], and sunflower stalks (used to remove direct blue dye) [ 16 ]. Nanoparticles have also been used for the removal of dyes, including TiO 2 nanoparticles (which have been investigated for their sorption capacity and photocatalytic efficiency [ 22 ]) and hollow zein nanoparticles for the removal of reactive blue [ 23 ]. Polyvinyl alcohol membranes containing scleroglucan, cellulose microfibers, or zein have been used for the removal of crystal violet [ 24 ].…”
