“…It has been reported that the dye degradation is associated with the breakdown of chromophoric group of the methylene blue and the transformation of dye into the low molecular weight by-products. The results are consistent with previous studies reported the degradation of methyl orange and methylene blue using FeNPs synthesized from Amaranthus spinosus (Garole et al 2018 ).The mechanism of degradation of dye took place due to the generation of surface plasmons under resonant excitation with molecular environment (Tsibul’nikova et al 2015 ). It was also described by Maji et al ( 2007 ) that the mechanism of degradation of dye might be due to photo-absorption, electrons and holes generation, charge carriers transfer and the recombination of carrier with the dye molecules.…”

The present study was investigated to synthesis the iron nanoparticles (FeNPs) using the leaf extract of Phyllanthus reticulatus . The phytosynthesized FeNPs exhibited UV–visible absorption peaks at 229 nm and its crystalline nature was confirmed through XRD. FT-IR analysis revealed the presence of various functional groups which are responsible for the bioreduction of FeNPs. The SEM results showed that FeNPs were aggregated, irregular sphere shaped with rough surfaces and EDX spectrum recorded densely occupied iron nanoparticles region. The particle size range of the synthesized iron nanoparticles was 185.6 nm. The FeNPs showed potential methylene blue decolourisation activity which was visually observed by gradual colour change in the dye solution from deep blue to colorless. The control exhibited no change in coloration during exposure to sunlight and the iron nanoparticles completely disintegrated the methylene blue within 10 s in 10 mg/L methylene blue (98%), whereas the color change was decreased when the concentration of the dye increased. In addition, the phyto-synthesized FeNPs exhibited extensive antibacterial and antifungal activity against the selected pathogens. Phytotoxicity assay confirms the potential of biosynthesized iron nanoparticles as a fertilizer for the growth of green gram seeds. Thus the present study leads to development of cost-effective green synthesis, reduction of toxic chemicals and its extensive applications in the biological sciences.

“…The small bands from 1,075.63 to 1,373.78 cm −1 correspond to ─C═O stretching of ether, ─C─O vibrations of carboxylic acid, ─C─N vibrations of primary amines . Small peaks obtained around 600–800 cm −1 occurred due to aromatic phosphate stretching (P─O─P) or monosubstituted aromatic rings . FTIR spectra of the plant extract confirmed the affluence of active biomolecules.…”

Present work deals with the facile and ecologically viable production of iron nanoadsorbents by utilizing different waste plant biomass, orange peel, flower waste, and environmentally harmful Alligator weed. The as‐prepared nanoadsorbents were applied for the aqueous phase minimization of toxic dyes, alizarin red S and tartrazine. Different techniques, namely, X‐ray diffraction, Fourier transform infra‐red spectroscopy, scanning electron microscopy, dynamic light scattering and magnetic properties measurement system, were applied to characterize the synthesized material. Impact of various experimental conditions like pH, adsorbent dose, contact time, and temperature on removal trend was examined. The acidic medium positively favored the process of sorption. Kinetic analysis revealed that the adsorption of both the dyes followed pseudo‐second‐order kinetic model. Equilibrium sorption data were fitted better to Freundlich model as compared with Langmuir model. The maximum adsorption capacities at 50°C were 42.58 and 68.78 mg g–1 for alizarin red S and tartrazine at pH 4.0 and 2.0, respectively. Thermodynamic parameters exhibited that the sorption of both the dyes onto nanoadsorbent was spontaneous and endothermic with increased randomness at the solid–liquid interface. Desorption experiment demonstrated that the regenerated adsorbent can be recycled efficiently up to three times. Overall, the prepared nanomaterials exhibit remarkable removal competency for both dyes tested like alizarin red S and tartrazine.

Catalysis represents the cornerstone of chemistry, since catalytic processes are ubiquitous in almost all chemical processes developed for obtaining consumer goods. Nanocatalysis represents nowadays an innovative approach to obtain better properties for the catalysts: stable activity, good selectivity, easy to recover, and the possibility to be reused. Over the last few years, for the obtaining of new catalysts, classical methods—based on potential hazardous reagents—have been replaced with new methods emerged by replacing those reagents with plant extracts obtained in different conditions. Due to being diversified in morphology and chemical composition, these materials have different properties and applications, representing a promising area of research. In this context, the present review focuses on the metallic nanocatalysts’ importance, different methods of synthesis with emphasis to the natural compounds used as support, characterization techniques, parameters involved in tailoring the composition, size and shape of nanoparticles and applications in catalysis. This review presents some examples of green nanocatalysts, grouped considering their nature (mono- and bi-metallic nanoparticles, metallic oxides, sulfides, chlorides, and other complex catalysts).
