“…Moreover, phenol and carboxylic acids were also observed to be present in Co 3 O 4 :PdO/Pd and Co 3 O 4 :NiO signifying the presence of plant phenolic compounds. The identified functional groups have been reported as stabilizing agents of synthesized nanomaterials 1,2,12,30–34 . Consequently, FTIR analysis showed stabilization of Co 3 O 4 by phytochemicals having hydrocarbon and amine functional groups while Co 3 O 4 :PdO/Pd and Co 3 O 4 :NiO were incorporated with phenolic compounds as stabilizing agents.…”

BACKGROUND: During recent years, great efforts have been devoted towards the functionalization of metal oxide nanomaterials with various carbonaceous groups to enhance their catalytic performance for environmental remediation applications such as dye degradation. Here, we synthesized Co 3 O 4 , Co 3 O 4 :NiO and Co 3 O 4 :PdO/Pd nanomaterials via organic compounds of Abies pindrow Royle following a hydrothermal route and then investigated them as catalysts for the degradation of methyl orange in aqueous solution in the presence of solar light as well as under dark ambient conditions. RESULTS: The chemical composition and phase analysis of Co 3 O 4 , Co 3 O 4 :NiO and Co 3 O 4 :PdO/Pd were confirmed using X-ray diffraction, energy-dispersive X-ray spectroscopy and Raman spectroscopy, while spherical nanostructures were observed using field emission scanning electron microscopy. Carbon-and oxygen-containing functional groups were revealed using Fourier transform infrared spectroscopy and gas chromatography-mass spectrometry. The catalytic efficiency of the functionalized nanocatalysts was enhanced to 99% and 98% by incorporation of NiO and PdO/Pd, respectively, within 15 min in the presence of solar light. Whereas, under dark conditions, the degradation efficiency of Co 3 O 4 :PdO/Pd and Co 3 O 4 :NiO was calculated as 75% and 77%, respectively. The catalysts demonstrated excellent reusability in four cycles of experiments with pseudo-firstorder kinetics (R 2 < 1) in the light and under dark conditions. CONCLUSIONS: The findings demonstrated an efficient and sustainable bio-templated synthesis of nanocatalysts for removal of organic dyes from aqueous environment. The excellent photocatalytic potential of phytosynthesized Co 3 O 4 :PdO/Pd and Co 3 O 4 : NiO was attributed to nanostructures as well as to incorporated carbonaceous compounds.

To deal with fossil fuel depletion and the rise in global temperatures caused by fossil fuels, cheap and abundant materials are required, in order to fulfill energy demand by developing high-performance fuel cells and electrocatalysts. In this work, a natural organic agent has been used to synthesize nanostructured ZnO/Mn 3 O 4 with high surface area and enhanced electrocatalytic performance. Upon preannealing treatment, mixed metal oxide precipitates are formed due to the complex formation between a metal oxide and organic extract. The thermally annealed mixed oxide ZnO/Mn 3 O 4 was characterized by XRD diffractometer, Fourier transform infrared spectroscopy (FTIR), X-ray photoelectron spectroscopy (XPS), field emission scanning electron microscopy (FE-SEM), transmission electron microscopy (TEM) and energy dispersive X-ray spectroscopy (EDX). Gas chromatography-mass spectrometry (GC-MS) identified methyldecylamine as a major stabilizing agent of the synthesized nanomaterial. Using a Tauc plot, the calculated band energy for the synthesized ZnO/Mn 3 O 4 mixed metal oxide was 1.65 eV.Moreover, we have demonstrated the effects of incorporated organic compounds on the surface chemistry, morphology and electrochemical behavior of ZnO/Mn 3 O 4 . The phyto-functionalized ZnO/ Mn 3 O 4 was deposited on Ni-foam for electrocatalytic studies. The fabricated electrode revealed good performance with low over-potential and Tafel slope, suggesting it to be suitable as a potential catalyst for water splitting application, in particular for the oxygen evolution reaction (OER). The overall findings of the current study provide a cost-effective and efficient organic template for functionalization and sustainable fabrication of ZnO/Mn 3 O 4 nanomaterial for application as an electrocatalyst.

: The Fungal infections are diseases that are considered neglected although their infection rates have increased worldwide in the last decades. Thus, since the antifungal arsenal is restricted and many strains have shown resistance new therapeutic alternatives are necessary. Nanoparticles are considered important alternatives to promote drug delivery. In this sense, the objective of the present study was to evaluate the contributions of newly developed nanoparticles to the treatment of fungal infections. Studies have shown that nanoparticles generally improve the biopharmaceutical and pharmacokinetic characteristics of antifungals, which is reflected in a greater pharmacodynamic potential and lower toxicity, as well as the possibility of prolonged action. It also offers the proposition of new routes of administration. Nanotechnology is known to contribute to a new drug delivery system, not only for the control of infectious diseases, but for various other diseases as well. In recent years, several studies have emphasized its application in infectious diseases, presenting better alternatives for the treatment of fungal infections.
