“…Further bio-based fabrication is reproducible and resulting nanoparticles are hydrophilic, which enhances its applicability in bioremediation. A comparison of these results with earlier reports [11,12] indicated that enzymes/ proteins, amino acids, polysaccharides, alcohols, phenols, and alkanes in Parthenium may be participating in the process. P. hysterophorus leaves contain myricyl alcohol, campesterol, stigmasterol, β-sitosterol, free amino acids, ursolic acid, 2β, 13α-dimethoxydihydroparthenin, salicylic acid, and protocatechuic acid [13].…”

In the present work, we have reported a sustainable and effective method for the degradation of a textile dye Reactive Red 31 (RR31) using synthesized titanium nanoparticles. Titanium dioxide nanoparticles were synthesized using a noxious weed, Parthenium hysterophorus, as reducing and capping agent for the first time. The synthesized nanoparticles were characterized and confirmed as TiO 2 nanoparticles by using X-ray diffraction spectroscopy, Fourier transformation infrared spectroscopy, and scanning electron microscopy analysis. A glass reactor was designed and developed for the degradation of dye under solar radiations. Photocatalytic degradation of Reactive Red 31 was carried out at different concentrations using synthesized nanoparticles. UV-vis spectroscopy, total organic carbon, and total inorganic carbon analysis were carried out for the determination of dye degradation. The results reveal that biogenic TiO 2 nanomaterial acts as a good photocatalyst for the degradation of textile dye Reactive Red 31.

Titanium dioxide nanoparticles (TiO2 NPs) are considered to be among the best photocatalytic materials due to their long-term thermodynamic stability, strong oxidizing power, and relative non-toxicity. Nano-preparations with TiO2 NPs are currently under investigation as novel treatments for acne vulgaris, recurrent condyloma acuminata, atopic dermatitis, hyperpigmented skin lesions, and other non-dermatologic diseases. The present study was to investigate the acaricidal and larvicidal activity of synthesized TiO2 NPs utilizing leaf aqueous extract of Mangifera indica L. (Anacardiaceae) against hematophagous parasites. The anti-parasitic activity of TiO2 NPs against the larvae of Rhipicephalus (Boophilus) microplus, Hyalomma anatolicum anatolicum and Haemaphysalis bispinosa (Acari: Ixodidae), fourth instar larvae of Anopheles subpictus, and Culex quinquefasciatus (Diptera: Culicidae) were assessed. The green synthesized TiO2 NPs were analyzed by UV-Vis, FTIR, X-ray diffraction (XRD), AFM, SEM, and TEM. The XRD analysis of synthesized TiO2 NPs revealed the dominant peak at 2θ value of 27.81 which matched the 110 crystallographic plane of the rutile structure indicating the crystal structure. The FTIR spectra exhibited a prominent peak at 3,448 cm(-1) and showed OH stretching due to the alcoholic group, and the OH group may act as a capping agent. The SEM images of TiO2 NPs displayed spherical, oval in shape, individual, and some in aggregates. Characterization of the synthesized TiO2 NPs using AFM offered three-dimensional visualization and uneven surface morphology. The TEM micrograph showed agglomerates, round and slight elongation with an average size of 30 ± 5 nm. The maximum efficacy was observed in synthesized TiO2 NPs against the larvae of R. microplus, Hyalomma anatolicum anatolicum, Haemaphysalis bispinosa, A. subpictus, and Culex quinquefasciatus with LC50 value of 28.56, 33.17, 23.81, 5.84, and 4.34 mg/L, respectively. In the present study, a novel, simple, and eco-friendly approach has been suggested to control blood-feeding parasites.

“…All these methods are very expensive, it takes high pressure, requires high energy or causes environmental pollution while the green synthetic method is found to be advantageous over other methods reported. Green synthesis method provides the nano range (10-100 nm) of the nanoparticles using the plant extracts and also parts of plants like leaves, flowers, fruits, seeds, fungi, yeast, algae and bacteria [18,19]. The plant extract plays a role in reducing and capping agents on the surface of the nanoparticles.…”

An ecofriendly TiO 2 from a plant extract of Averrhoa bilimbi with cost effective and non-toxic with cis dithiocynato-N, N-bis(2,2-bipyridyl-4,4-dicarboxylic acid)ruthenium(II) (N3 dye) in dyesensitized solar cells (DSSC) reports better efficiency of 5.2%. The green synthesized TiO 2 nanoparticles along with 2,4-Diamino-6-Phenyl-1-3-5-Triazine (DPT) doped Poly(ethylene glycol) (PEG)/KI/I 2 /Pt shows better efficiency in dye-sensitized solar cells. The green TiO 2 was characterized with XRD, UV, FTIR, SEM, TEM and EDX techniques confirm the band gap of 3.2 eV and 15 nm size for TiO 2 . The mechanical and electrical properties of DPT doped PEG/KI/I 2 polymer electrolyte were characterized with XRD, FTIR, EIS, DSC and TGA and it was confirmed that the DPT well miscible with PEG polymer electrolyte and improves the electrical conductivity and enhances the efficiency of DSSC.
