Synthesis and characterization of NiFe2O4–Pd magnetically recyclable catalyst for hydrogenation reaction

Impact of Covalent Functionalization on the Aqueous Processability, Catalytic Activity, and Biocompatibility of Chemically Exfoliated MoS2 Nanosheets

“…For example, the catalytic activity of acetic acid-functionalized ce-MoS 2 towards 4-NP reduction after three months (~2 h -1 ) lay in the lower range of values typically documented for catalysts based on expensive noble metal (e.g., Pt or Pd) NPs, [41][42][43][44][45][46] whereas it was similar to or somewhat higher than that of non-noble metal (e.g., Cu) NP-based catalysts [47][48][49][50] but much higher than that of novel metal-free catalysts based on heteroatom-containing carbon materials, such as nitrogen-doped reduced graphene oxide. [51][52][53][54][55] In the case of 4-NA reduction, the long-term catalytic activity of the functionalized nanosheets (27.6 h -1 ) was comparable to the values typically reported with noble metal NP-based catalysts [56][57][58][59][60][61][62] and much higher than that of nitrogen-doped reduced graphene oxide 21 (data for catalysts based exclusively on non-noble metal NPs are not available for this reaction in the literature). The abundant presence of covalently grafted acetate groups on ce-MoS 2 can also be beneficial towards the production of hybrids with metallic or semiconducting NPs, because the carboxylate moieties can act as effective anchoring sites that favor the nucleation and/or attachment of such NPs onto the nanosheets.…”

Novel magnetic NiFe2O4/multi-walled carbon nanotubes hybrids: Facile synthesis, characterization, and application to the treatment of dyeing wastewater

“…Among those MeFe 2 O 4 , NiFe 2 O 4 with a narrow band gap of 2.19 eV exhibits characteristics of excellent visible-light response, favorable magnetism, as well as good photochemical stability [5]. Recently, NiFe 2 O 4 has been used as photocatalyst for the hydrogenation reaction [9,10] and effective removal of environmental pollutants, such as organic dyes [11,12] and di-n-butyl phthalate [5].…”

“…Then all produced active species oxidized further the broken CR molecules to all kinds of inorganic small molecular such as CO 2 , H 2 O and other small molecule byproducts(9).…”

Magnetic nickel ferrite nanoparticles as an efficient catalyst for the preparation of polyhydroquinoline derivatives under microwave irradiation in solvent-free conditions

“…Nickel ferrite MNPs are inexpensive, air-stable, magnetically separable, and economical catalysts [41][42][43][44]. There are very limited and there are less references about catalytic properties of nickel ferrite MNPs [45][46][47]. These spinel-type bimetal oxides, have shown great potential in the field of use for catalysis, although they have so far been less investigated.…”
