In this paper, the potential use of either amine-functionalized or hydroxyl-functionalized magnesium ferrite (MgFe2O4) nanoparticles (NPs) as Congo red nanoadsorbents is explored and compared. The MgFe2O4 NPs (denoted MgFe2O4–NH2 NPs) were synthesized by a one-pot coprecipitation method using ethanolamine surface modifier, while MgFe2O4–OH prepared hydrothermal method. general, both can be successfully produced without calcination found to possess superparamagnetic properties with high...
Magnetic nanoadsorbent in the form of amine-functionalized MgFe<sub>2</sub>O<sub>4</sub>nanoparticles was successfully synthesized and adopted for Pb<sup>2+</sup>removal from scenario simulated wastewater.
Surface modification of silica-coated magnesium ferrite nanoparticles (MgFe2O4@SiO2 NPs) by 3-aminopropyltriethoxysilane (APTES) shows enhanced selectivity for the removal Congo Red (CR) from both single and binary aqueous dye solutions. Before coating surfaces amine-functionalized (MgFe2O4–NH2 with silica, control studies adsorption cationic, neutral, anionic dyes were performed using systems. The found that MgFe2O4–NH2 nanoadsorbent favors indigo carmine (IC) CR in solutions (>90%...
Active surface oxygen and hydroxyl groups play a decisive role in catalyzing the oxidation of 5-hydroxymethylfurfural (HMF) to 2,5-furandicarboxylic acid (FDCA) over β-MnO 2 .
The geometry, arrangement, and orientation of a quaternary ammonium surfactant flanked by two methyl groups, benzyl head, an octyl tail were assessed at the air–water air-deuterium oxide (D2O) interfaces using sum frequency generation vibrational spectroscopy. Remarkably, symmetric asymmetric N–CH3 stretches (at ∼2979 ∼3045 cm–1, respectively, in SSP polarization combination) visible water but negligible deuterium oxide. We concluded that D2O addition triggers average reorientation dimethyl...
Successive surface reactions on hydrophilic silica substrates were designed and performed to immobilize ethanolamine-modified magnetic ferrite-based nanoparticle (NP) for characterization. The various surfaces monitored using sum-frequency generation (SFG) spectroscopy. of the quartz substrate was first converted a vinyl-terminated by utilizing silanization reaction, then, functional groups carboxylic-terminated via thiol–ene reaction. appearance disappearance vinyl (═CH2) peak at ∼2990 cm–1...
Surface deposition of magnesium ferrite nanoparticles (MgFe2O4 NPs) with bimetallic gold/silver (Au/Ag) was conducted using the seed-mediated growth method to obtain magnetic–metallic composite catalysts for use in catalytic reduction nitroaromatics. Two types amine-functionalized MgFe2O4 and MgFe2O4@SiO2 NPs were used as magnetic supports surface process. The combination several characterization analyses (i.e., XRD, XPS, TEM, SEM, EDS, VSM) confirmed successful syntheses MgFe2O4/Au/Ag...
Lignin is a promising feedstock for renewable fuels and chemicals due to its aromatic skeleton natural abundance. can be converted diverse monomers as well dicarboxylic acids depending on the applied conversion technologies. Despite great potential, native processing-induced heterogeneity complexity limit efficiency product selectivity. In this study, magnesium ferrite (MgFe2O4) nanoparticle–peracetic acid (PAA) has been investigated an efficient catalyst–oxidant incorporation catalytic...
This work addresses the domain evolution processes in polycrystalline barium titanate (BaTiO3, BT)-based ceramics containing various amounts of gold nanoparticles (AuNPs) as an additive by using piezoresponse force microscopy (PFM). The obtained PFM images AuNPs-modified BT revealing change one spontaneously polarized state to another under applied direct current (DC) voltage are discussed terms their topology, phase shift and amplitude. In general, complex microstructures almost...

The catalytic deoxygenation of coconut oil was performed in a continuous-flow reactor over bimetallic NiCo/silicoaluminophosphate-11 (SAPO-11) nanocatalysts for hydrocarbon fuel production. conversion and product distribution were investigated NiCo/SAPO-11 with different applied co-reactants, i.e., water (H2O) or glycerol solution, under nitrogen (N2) atmosphere. hydrogen-containing co-reactants proposed here as in-situ hydrogen sources the deoxygenation, while reaction tests (H2) atmosphere...
