newline ix newlineAbstract newlineRecent time is the period of technological development which shows changes in the use of advance materials. Latest scientific skills are very much useful in the development of nanoparticles and nanocomposites. Multifunctional materials i.e. nanocomposites have the ability of combining the properties of two or more than two different materials. Thus, attempts have been made to synthesis the multifunctional nanocomposite with applicability in diverse fields. In present work, we have synthesized trimetallic nanoparticles and their novel nanocomposites which are used for different applications such as water purification, catalytic activities and antibacterial agents. newlineIn the presence study, the Fe/La/Zn TNPs, Fe/La/Znatand#946;-CD and Fe/La/ZnatGO TNCs were synthesised by using micro-emulsion method and used as a photocatalysts for the remediation of the organic pollutants. The prepared Fe/La/Zn TNPs and their nanocomposites, were characterized by mean of the X-Ray diffraction (XRD), fourier transform infra red spectroscopy (FTIR), scanning electron microscopy (SEM) and transmission electron microscopy (TEM). The potential applications of the TNPs and TNCs were explored for photodegradation of phenylhydrazine and amoxicillin in the presences of sunlight. The photocatalytic studies were performed under two sets of conditions: (i) equilibrium adsorption in dark followed by photocatalysis and (ii) simultaneously adsorptional/photocatalysis directly in sunlight. In case of phenylhydrazine it was observed that 63% reduction was achieved under sunlight in the presence of Fe/La/Znatand#946;-CD which higher when compared to Fe/La/Zn TNPs (52%) and Fe/La/ZnatGO TNCs (57%). Fe/La/Znatand#946;-CD is more effective in simultaneously adsorptional photocataytic conditions for amoxicillin remediation with a whopping 78% degradation achieved in 4 hours. The optical band gap of Fe/La/Zn TNPs, Fe/La/Znatand#946;-CD and Fe/La/ZnatGO TNCs was found to be 2.73 eV, 2.67 eV, and 2.30 eV which lies in semiconductor region. newlinex newlineThe catalytic nature of synthesized TNPs and TNCs were explored for oxidation and esterification reactions. It was observed that in the presence of acetonitrile with ratio 2:1 (BA:H2O2) and Temperature (80°C) Fe/La/Zn TNPs gives maximum yield 93.7% and Fe/La/ZnatGO TNCs also gives 93.7% yield at 100°C. newlineThe synthesized TNPs and TNCs showed the promising antimicrobial activity against E. coli and S. aureus. The against E.coli the inhibition zone was found to be maximum at 150 and#956;g/mL for Fe/La/Zn TNPs (19 mm), Fe/La/Znatand#946;-CD TNCs (16 mm) and Fe/La/ZnatGO TNCs (17 mm) and against S. aureus at concentration of 150 and#956;g/mL the inhibition zone was found to 18 mm for Fe/La/Zn TNPs, 14 mm for Fe/La/Znatand#946;-CD TNCs and 15 mm for Fe/La/ZnatGO TNCs. newlineThe present study revealed that the synthesized TNPs and TNCs is a new class of advanced multifunctional material which can be employed effectively for environmental remediation, in catalytic activities and antimicrobial studies. newlineKey words:- TNPs, TNCs, UV-Vis, FTIR, XRD, NPs, CDS, GO.
