Iron oxide nanoparticles–cellulose: a comprehensive insight on nanoclusters formation

A Novel Recyclable Magnetic Nano-Catalyst for Fenton-Photodegradation of Methyl Orange and Imidazole Derivatives Catalytic Synthesis

“…cotton spectrum shows the appearance of two characteristic bands around 883 and cm −1 , ascribed to the stretching and bending vibrations of C-Cl, respectively [25]. T changes confirm the substitution of hydroxyl groups by chlorine atoms in (6-CDC) The intense band recorded at approximately 590 cm −1 is ascribed to the Fe-O stretc vibration [47]. This peak proves the successful coating of Fe3O4 nanoparticles on the m ified cotton surface [48].…”

“…Numerous studies have reported that Fe 3 O 4 nanoparticles exhibit direct band gap values ranging from 2.02 eV to 2.69 eV [ 44 , 45 ]. According to Deotale et al [ 46 , 47 ], the bandgap of nanoparticles may be influenced by three factors: surface and interface effects, changes in the crystal structure due to heat treatment, and the Lattice strain within the sample.…”

“…Numerous studies have reported that Fe 3 O 4 nanoparticles exhibit direct band gap values ranging from 2.02 eV to 2.69 eV [44,45]. According to Deotale et al [46,47], the bandgap of nanoparticles may be influenced by three factors: surface and interface effects, changes in the crystal structure due to heat treatment, and the Lattice strain within the sample. The designed photocatalyst and its corresponding ligand (CDC) showed maxima absorptions at ~360 and 438 nm, with absorption edges in the ranges of 320-380 and 340-500 nm, respectively, indicating that both synthesised materials are photolytically active in both the UV and visible regions.…”

Microbial synthesis of titanium dioxide nanoparticles and their importance in wastewater treatment and antimicrobial activities: a review

“…Nanotechnology and nanoscience have gained huge importance in the last few years due to their exceptional features (Ray and Bandyopadhyay, 2021 ; Modi et al, 2022b ; Zanata et al, 2022 ). Nanoparticles (NPs) have gained attention in the fields of environmental cleanup, electronics, research, medicine, etc.…”
