“…The present CoONPs shows 92.20% DE of MX at neutral pH with visible light irradiation indicates faster degradation rate. On the flipside, most of the reported conventional catalysts for the degradation of TY are TiO 2 or ZnO based nanoparticles induced by UV light [46][47][48] . Recently, Pal et al [45] have reported an efficient photocatalyst, ZnO nano particles synthesized by using Moringa Oleifera leaf extract which degrades TY about 96.0% under 60 min visible light irradiation in the pH range 2.0-12.0.…”

Considering the impact of organic dyes as industrial effluents on the environment, this research study describes the synthesis, structural and morphological characterization, and visible light induced photo-catalytic studies of cobalt oxide nanoparticles (CoONPs). In order to synthesize the CoONPs, a tetra-nuclear cobalt(III)-Schiff base complex was prepared in crystalline phase and employed to produce CoONPs through thermal decomposition of the synthetic precursor. The morphology of the nanoparticle has been delineated with different spectroscopic and analytic methods. Scanning and transmission electron microscopy (FE-SEM and HR-TEM) analyses estimate the cauliflower structured CoONPs with an average size ~80 nm. The photo-catalytic behavior of CoONPs has been tested against murexide and titan yellow dye in aqueous phase. This CoONPs ensure more than 90% of degradation for murexide while ~60% degradation has been observed for titan yellow (TY) in aqueous phase for a same time interval. MX and TY adopt different structures which bring the variation in rate of photosensitization for the synthetic CoONPs photocatalyst and account on the different photocatalytic efficiency towards the degradation of MX and TY in presence of visible light.

“…Furthermore, the use of these materials can improve the pharmacological and photocatalytic properties of the NPs produced. Bio-mediated TiO2 NPs have also been reported from Azadirachta indica [15], Morinda citrifolia L. [16] and Tamarindus indica [17] extracts. Fungi, actinomycetes, bacteria and plant extracts [18] have replaced chemical agents in the green synthesis materials [19].…”

The surface chemistry of nanostructures concerning their smaller sizes, unique optical and electronic properties continue to benefit organic medicinal chemistry and biosynthesis of active titania nanoparticles with metabolites present in plant extracts. Deinbollia pinnata ethyl acetate leave extracts with sol-gel method afforded titania nanoparticles (TiO2 NPs-anatase) with photodegradation performance at 98.7% of methyl orange (MO) conversion within 150 mins. Together with observed participation of π-π* transition state more than that of η-π* state. The GC-MS spectrum revealed classes of compounds which include long-chain fatty acids, galloyl ester, long-chain esters, tetraterpenoids, triterpenoids, sesquiterpenoid terpenoid (isoprenoids) with a correlation maximum of stigmasterol (94%)as phytochemical contents of the crude extracts. The physiochemical analysis using X-ray diffraction (XRD) showed average crystallite size in the range of 19 – 21 nm, field emission scanning electron microscopy (FESEM) displayed uniform semi-spherical shape in the size range of 33 – 48 nm, energy dispersive X-ray (EDX) spectra depicted main elements of Ti (61 Wt.%) and O (35 Wt.%), UV-Vis spectroscopy exhibited band-gap energy of 3.2 eV, nitrogen sorption analysis specified type IV isotherm and BET surface area of 31.77 m2/g. The super-striking green TiO2 NPs photodegradation in this work with wide-ranged transitional states involvement, can, in turn, be used as bio-mediated TiO2 NPs in medicinal chemistry to enhance pharmacokinetics, pharmacological properties and replace chemical agents thereby reducing side effects at drug delivery site actions. Thus, natural products continue to integrate research advances and innovation.

The biosynthesis procedure for nanomaterial preparation is a promising alternative due to its simplicity and environmental friendliness. In this work, TiO2 NPs were biosynthesized using the aqueous leaf extract of Azadirachta indica. The influence of the extract volumes, solvents, and acetic acid on the properties of TiO2 NPs was studied. Phytochemical screening and ATR-FTIR spectrum confirmed the presence of phenolic compounds in the leaf extract. XRD patterns showed that the samples were mainly in the anatase phase. However, for the water-based samples and when 1 and 2 mL of extract volumes were used, anatase/brookite mixture was observed. FESEM images displayed almost spherical and agglomerated NPs. UV-Vis-NIR studies showed that the samples’ bandgaps values are within the range of anatase TiO2. The photocatalytic activity of the TiO2 NPs was evaluated in the photodegradation of methyl orange (MO) under UV light irradiation. The water-based sample synthesized using 2 mL of the extract achieved 98.62% of MO degradation within 270 min and demonstrated the highest pseudo-first-order photodegradation kinetic constant of 0.0147 min-1. These results indicate that the use of the plant-based biosynthesis method with water as the solvent successfully produced TiO2 NPs with good physicochemical properties and photocatalytic activity in the photodegradation of organic dye.
