• Organic-inorganic hybrids of polythiophene (PTh) decorated ZnFe 2 O 4 nanoparticles. • Microwave-assisted catalytic degradation of Isoniazid drug. • 94% degradation in 24 min. • Analysis of degraded fragments. • Fukui index and proposed degradation pathay. This present work reports for the first time, microwave-assisted catalytic degradation of isoniazid drug using organic–inorganic hybrids of polythiophene (PTh) decorated ZnFe 2 O 4 nanoparticles. The hybrids were characterized using fourier transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD) and scanning electron microscopy along with energy dispersive spectra (SEM-EDS). The nanohybrids were used as catalysts for the degradation of isoniazid (ISN) drug under microwave irradiation. Almost 94% degradation of isoniazid was attained within 24 min using 100 mg of the catalyst. The degraded drug fragments were analyzed using LCMS and a tentative mechanism of degradation was proposed. [ABSTRACT FROM AUTHOR]

The development of multifunctional materials, specially nanocomposites, exhibit new and interesting properties which can extend the applicability ranges to diverse fields. In this way, the use of tri metallic nanoparticles, and derives, demonstrated higher efficacy for purification, catalytic activities and as antibacterial agents. This work is concentrated on the fabrication of Fe/La/Zn trimetallic nanoparticles (TNPs) and Fe/La/Zn@GO trimetallic nanocomposite (TNC) using the micro-emulsion method, specially indicated as photocatalysts for remediation of the organic pollutant. An intense characterization was performed by employing techniques as scanning electron microscopy (SEM), X-Ray diffraction (XRD), transmission electron microscopy (TEM) and Fourier transform infrared spectroscopy (FTIR). The potential applications of the Fe/La/Zn TNPs and Fe/La/Zn@GO TNC were explored for the photodegradation of phenylhydrazine in the presences of sunlight. Furthermore, the photocatalytic studies were performed under different conditions: (a) adsorption (in dark) followed by photocatalysis, and (b) simultaneously adsorptional-photocatalysis straight way in sunlight. It was observed that a reduction of 52% and 57.91% was achieved under sunlight using Fe/La/Zn TNPs and Fe/La/Zn@GO TNC, respectively. The optical band gap of Fe/La/Zn TNPs, and Fe/La/Zn@GO TNCs was found 2.73 eV and 2.30 eV, which lies in semiconductor region. On the other hand, the antimicrobial nature of TNPs and TNC was checked for E. coli and S. aureus. The inhibition zone exhibited a maximum at 150 μg/mL for Fe/La/Zn TNPs (19 mm), and Fe/La/Zn@GO TNC (17 mm). This study revealed that resulting materials can be defined as a novel class of advanced multifunctional materials which can be employed effectively for environmental remediation and antimicrobial studies.

In the present work, we synthesized La/Cu/Zr trimetallic nanoparticles (TNPs) by microwave method, which is applied as an effective nanophotocatalyst for the removal of a ampicillin antibiotic from aqueous media. The prepared nanomaterial was characterized by Fourier transform infrared (FTIR) spectroscopy, X-ray diffraction (XRD), scanning electron microscopy (SEM), and transmission electron microscopy (TEM). The experimental results showed that prepared nanoparticles have high photodegradation tendency for the removal of ampicillin antibiotic from the aqueous solution. The pseudo-first-order equation represents the better kinetics of the photocatalytic process. The feasibility of ampicillin antibiotic adsorption onto La/Cu/Zr TNPs was also studied and the results showed that the adsorption was supported with spontaneous photodegradation process. A photocatalytic degradation 86% of the antibiotic has been observed. [ABSTRACT FROM AUTHOR]

Iron molybdophosphate (FeMoPO) nanoparticles have been fabricated using simple co-precipitation method. The nanoparticles showed promising ion exchange nature with ion exchange capacity of 1 meq g − 1 .The synthesis on nanoparticles has been ascertained by characterizing the material using various techniques including Fourier transform infrared spectroscopy (FTIR) scanning electron microscopy (SEM) and transmission electron microscopy (TEM). To investigate the ion exchange behavior of FeMoPO nanoparticles its physicochemical properties has been studied in detail such as thermal stability, pH titrations, and elution behavior. FeMoPO nanoparticles have been explored as potential candidature for photocatalytic remediation of malachite green (MG) dye from aqueous system. It has been observed that FeMoPO nanoparticles efficiently photodegraded 77% of hazardous MG dye in 5 h of photo-exposure. [ABSTRACT FROM AUTHOR]
