Application of deep eutectic solvent for conjugation of magnetic nanoparticles onto graphene oxide for lead(II) and methylene blue removal

A eutectogels-catalyzed one-pot multi-component reaction: access to pyridine and chromene derivatives

“…The aforementioned explanation applies to the adsorption bands within the spectral range of 3600 to 3000 cm −1 . The FT-IR analysis of ETG-acetamide revealed new peaks at 866 cm −1 , 953 cm −1 and 1394 cm −1 , indicating the presence of C-N + stretching and CH 3 bending from DES, 15,[39][40][41] conrming the successful incorporation of ETG-acetamide.…”

Design Strategy and Application of Deep Eutectic Solvents for Green Synthesis of Nanomaterials

“…Applying DESs for graphene oxide functionalization and nanoparticle conjugation has recently been investigated and applied in drug delivery, water treatment, catalysis, and biosensor application [ 199 , 200 ]. The modification and addition of functional groups to the surface of graphene were investigated with eighteen different types of ammonium- and phosphonium-salt-based DESs [ 200 ].…”

“…The study indicated the change in the surface chemistry of materials after DES functionalization according to the new hydrophilic functional groups and different reducing abilities of the used DESs. In another work, DES-based ChCl and U have been used to control the Fe 3 O 4 conjugate in graphene oxide (GO) ( Figure 7 b) [ 199 ]. The nanohybrid DES/GO-Fe 3 O 4 exhibited good characteristics of organic dye absorbents.…”

Recent Advances in the Synthesis of Inorganic Materials Using Environmentally Friendly Media

“…Among all the literature, although reline still plays an important role (since it features in approximately one out of four studies (80/343) on both traditional liquid-phase syntheses and electrodeposition), the interest in new methods has grown significantly and NADESs are becoming more and more important every day. Among the newest and most interesting investigations using “traditional” ChCl:urea, the latter DES was used: in the field of metal oxides synthesis, to prepare nontoxic photoluminescent SnO nanoparticles for cell imaging [ 87 ], in the solvothermal synthesis of iron oxide from iron monitored in operando by SANS and EXAFS [ 88 ], in the synthesis of ceria nanoparticles in a continuous microreactor [ 89 ], to conjugate Fe 3 O 4 nanoparticles on graphene oxide [ 90 ], to obtain NixCo 2 -x(OH) 3 Cl nanoparticles with an optimal Ni/Co ratio suitable for use as cathodic materials [ 91 ], as a solvent and nitrogen source for preparing fluorescent carbon dots [ 92 ], and for the synthesis of titanomagnetite NPs with enzyme-like activity [ 93 ]. Finally, reline was also used very recently as a template to prepare polyacrylates/nanohydroxyapatite scaffolds and polycrystalline sub-nanometrical chalcogen nanoparticles (SeTe) with high activity towards tumor cell lines [ 94 ].…”
