In the present work, we describe a cost-effective, simple, rapid and environmentally gracious biogenic fabrication of nickel/nickel oxide nanoparticles (Ni/NiO NPs) using Gymnema sylvestre as a natural fuel. The textural characteristics of as-prepared Ni/NiO NPs were explored using X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), diffuse reflectance spectra (DRS), photoluminescence spectroscopy (PL), field-emission scanning electron microscope (FESEM), energy dispersive X-ray analysis (EDX), and high-resolution transmission electron microscopy (HRTEM). XRD affirmed the crystalline nature and phase formation of Ni/NiO NPs. The FTIR spectrum ascertains the formation of Ni/NiO NPs, and the band gap of 4.29 eV is revealed from DRS studies. Ni/NiO NPs display an intense emission peak at 576.2 nm in their PL...

The known conventional routes for the production of NPs are complicated, noxious, expensive and not safer to human and environment. To overcome these threats, natural precursors such as biopolymers, plant, fungi, and bacteria have been used to fabricate the calcium oxide nanoparticles (CaO-NPs). The shape, size, and applications of the CaO-NPs are prominently affected by the reaction parameters under which they are synthesized. Moreover, the CaO-NPs synthesized by green approach have found potential applications in a wide spectrum of areas including, catalysis, bio-ceramics, additive in refractory, biodiesel production, adsorbent, antimicrobial agent, removal of Cr(VI) and trans esterification of oils.

catalytic applications are gaining significant enthusiasm in the field of nanochemistry.
Homogeneous catalysis is crucial due to its inherent benefits like high selectivity and mild
reaction conditions. Nevertheless, it endures with serious disadvantages of catalysts and/or
product separation/recycles compared to their heterogeneous counterparts restricting
their catalytic applications. The utilization of catalysts in the form of nano-size is an elective
methodology for the combination of merits of homogeneous and heterogeneous catalysis.
Magnesium oxide (MgO) NPs are important as they find applications for catalysis, organic
transformation, and synthesis of fine chemicals and organic intermediates. The applications
of MgO NPs in diverse organic transformations including oxidation, reduction, epoxidation,
condensation, and C-C, C-N, C-O, C-S bond formation in a variety of notable heterocyclic
reactions are also discussed. The use of MgO NPs in organic transformation is advantageous
as it mitigates the use of ligands; the procurable separation of catalyst for recyclability
makes the protocol heterogeneous and monetary. MgO NPs gave efficacious catalytic
performance towards the desired products due to high surface area. By considering these
efficient merits, scientists have focused their attentions towards stupendous applications of
MgO NPs in selective organic transformation. In the current review article, we summarized
the synthesis of MgO NPs and numerous characterization techniques, whereas the
application section illustrates their utility as a catalyst in several organic transformations.
We believe this decisive appraisal will provide imperative details to further advance the
application of MgO NPs in selective catalysis.

In this review, we summed up the general protocols and mechanisms of green synthesis routes, especially for silver (Ag), silver oxide (Ag 2 O), cadmium (Cd), copper (Cu), copper ferrite (CuFe 2 O 4), palladium (Pd), aceprophyline, cellulose and graphene nanomaterials/nanoparticles using cow urine. Importantly, we explored the main role of biological constituents which has existed in cow urine. These essential biomolecules act as reducing/stabilizing agents in solvent systems. The stability, phase formation, and surface morphology of NMs using characterization techniques are also discussed. Finally, we covered the eclectic applications of such synthesized NMs in terms of anti-asthma, antimicrobial, antituberculosis, antioxidant, anticancer activity, catalytic activity, and removal of pollutants dyes.

The prepared CuO NPs were characterized using X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM), energy-dispersive X-ray spectroscopy (EDX), Fourier transform infrared spectroscopy (FT-IR), UV-visible diffuse reflectance spectroscopy (UV-DRS), and photoluminescence (PL) analysis. The CuO NPs showed antifungal activity against Candida albicans, Aspergillus niger, Aspergillus clavatus, Trichophyton mentographytes, and Epidermophyton floccosum. The results revealed the successful synthesis of CuO NPs by simple green chemistry approach may provide a useful tool in the field of nanotechnology.

This has ameliorated an immense development of different synthetic pathways for SeNPs production. Preparation of SeNPs depends largely on the known chemical and physical methods that involved noxious chemicals and harsh reaction conditions which have been identified as a major disadvantage and potential threats to environment, health and its usage. Alternatively, biogenic synthesis has gained popularity as it is eco-benign, cheap, clean, and safe, generating minimal waste. In this review, we summarized recent literature on green synthesis of the SeNPs using various plants and plant parts which have revolutionized technique of fabrication for their applications in various fields. Due to the biocompatibility of the SeNPs, it has found its stupendous applications in biomedical field. The protocol, characterization techniques and biosynthesis of SeNPs along with various recent applications were also discussed. where he is working on synthesis of metal and metal oxide nanomaterials for biological & catalysis applications.

Currently, the sustainable improvement of synthesizing NPs by distinctive parts of plant extract has become a major focus of scientists and researchers, because these NPs have a minimum detrimental effect on ecosystem and minimum noxiousness for the human health. Among the metal oxide nanoparticles, alumina nanoparticles (Al 2 O 3 NPs) draw a special attention due to their significant applications in ceramics, textiles, drug delivery, catalysis, waste-water treatment and biosensor. Many natural biomolecules in plant extracts such as saponins, tannins, alkaloids, amino acids, enzymes, proteins, coumarins, polysaccharides, polyphenols, steroid and vitamins could be participated in bioreduction and stabilization of Al 2 O 3 NPs. In the last decade, innumerable efforts were made to develop a sustainable eco-accommodating method of synthesis to avoid the perilous byproducts. This review focuses on the plants used for the green fabrication of Al 2 O 3 NPs, their characterization methods and applications.

X-ray diffraction (XRD) pattern revealed the crystal planes and size of the synthesized CeVO 4 NPs. The morphological shape and the crystalline nature of the NPs were examined by field emission scanning electron microscopy (FESEM). Energy-dispersive X-ray spectroscopy (EDX) affirmed the presence of elemental composition and purity of the fabricated NPs. Fourier transform infrared spectroscopy (FT-IR) confirmed the conceivable stretching frequency on the surface of CeVO 4 NPs. UV-visible diffuse reflectance spectroscopy (DRS) absorption spectrum indicated that the band gap is about 3.2 eV and the synthesized tetragonal CeVO 4 NPs exhibited a broad photoluminescence in the UV-visible region. Besides, these CeVO 4 NPs evinced antifungal activity against Candida albicans, Aspergillus niger, Aspergillus clavatus, Trichophyton rubrum, Trichophyton mentographytes, Epidermophyton floccosum and Microsporum gypseum. The studies describing the synthesis of CeVO 4 NPs by simple sol-gel auto combustion method followed by the investigation of antifungal activities may be useful for the research activities to open a new horizon in the field of nanotechnology.
