This paper deals a novel method for the synthesis of silver nanoparticles (AgNPs) by microwave assisted approach using silver nitrate and trisodium citrate. The formation of nanoparticles was confirmed by UV-visible spectral studies. Particle size and morphology was determined by P-XRD and HR-TEM studies which revealed the average particle size of synthesized nanoparticles 21.49 and 20.08 nm respectively with spherical shape. The synthesized nanoparticles were screened for antibacterial activity in vitro against gram-positive bacteria Staphylococcus aureus and Bacillus subtilis and gram-negative bacteria Escherichia coli and Klebsiella pneumoniae by adopting disk diffusion method. The results of antibacterial studies exhibited that AgNPs were potential antibacterial agent.

Silver nanoparticles have been synthesized from the ethanol extract of Myristica fragrans seed. The synthesized nanoparticles were characterized by UV-visible, FT-IR, XRD, SEM, TEM and AFM spectral studies. Formation of silver nanoparticles conform through colour change from pale yellow to brown when ethanol extract of Myristica fragrans was added dropwise to silver nitrate. The appearance of brown color in aqueous solution is due to excitation of surface plasmon vibrations of silver nanoparticles observed between 400 – 450 nm. Peak corresponding to 1741 cm -1 confirms the presence of aldehyde groups in the ethanol extract of Myristica fragrans which is responsible for the capping and stabilization of biosynthesised. AEM images of silver nanoparticles exhibit uniformly distributed, well defined regular nanostructures. Silver nanoparticles showed significant antibacterial action on both the gram classes of gram-negative Escherichia coli and gram-negative bacteria Bacillus cereus .

Article history: Received 20 March 2019 Accepted 29 April 2019 Available online 04 June 2019 Many challenges of core/shell nanostructures for various applications still exist. The structure including the diameter, length, spacing and the thickness of the core or shell is difficult to control precisely. Metal nanoparticles used as various types of catalysts adsorbents and sensors. They have applications in optical, electronic and magnetic devices. Majority of these applications significantly depend on the size of the nanoparticles. Therefore, the synthesis of nanoparticles with controlled grain size is important. In the present work, Cadmium sulfide (CdS) was used as the core material which coated by the polypyrrole (PPy). To form the core and the shell set, the diameter fixed and measured theoretically. The calculated amount is used to prepare the shell which is formed by addition polymerization. The XRD studies are used to determine the particle size of the core shell nanocomposite. The average particle size of CdS and CdS/PPy is 13 nm and 15 nm respectively. Fourier transform infrared (FTIR) spectra and UV-Vis spectra are used to characterize the structure and to calculate the band gap of the core/shell nanocomposite. The AFM studies give the surface morphology of the samples.

Article history: Received 20 March 2019 Accepted 29 April 2019 Available online 04 June 2019 Lignosulfonate doped poly(o-anisidine) and poly(o-anisidine)/lignosulfonate polymer composite protected silver nanoparticles (AgNPs) were synthesized by interfacial polymerization method by mixing of an equal molar ratio of o-anisidine and lignosulfonate using silver nitrite as oxidizing agent. The polymerization reaction was carried out under reflux condition at 80 °C for 3 hours. The resulting AgNPs nanocomposite was isolated and then characterized by using various instrument method including UV-visible spectroscopy, FT-IR, and FE-SEM analysis. The catalytic behaviour of the polymer protected silver nanoparticle was studied for the reduction of 4-nitrophenol (4-NP) and textile dyes like methylene blue (MB) and Congo Red. The reduction of 4-nitrophenol using AgNPs/poly(o-anisidine) nanocomposite reaction follow the pseudo first order kinetics and the resulting rate constant was found to be 10 min-1 for 4.0×10-4 M concentration of 4-NP using 10 mg/L of catalyst. On the other hand, the catalytic behaviour of the nanocomposite was investigated toward the degradation of some of the textile dyes such as MB and Congo Red. The percentage of degradation of dye was monitored by UV-visible spectral studies and found to be superior to the other catalyst used for the degradation studies. The present method was employed for the effective removal of textile dyes and reduction of 4-nitrophenol with a minimum amount of catalyst.

Article history: Received 20 March 2019 Accepted 29 April 2019 Available online 04 June 2019 The present study describes the process for the formation of PANI nanocomposite incorporated with metal (Cd, Bi, Ba) molybdates of binary metal oxide. The PANI and its nanocomposites were prepared by 0.1 M aniline in 100 mL of 1 M sulphuric acid in the presence or absence of 50 mg of metal molybdate by chemical polymerization using 0.1 M APS as oxidant in 100 mL of 1 M sulphuric acid. The polymerisation yields are increased due to incorporation of metal molybdates. The growth of polymerization is also enhanced. The interaction of metal molybdates into PANI matrix leads to increase in very high conductivity, heavy interaction between the two-polymer chain lead to increase in stability of the polymer. In the incorporation of metal molybdate into the polymer matrix leads to increase in conductivity of about 5, 4 and 2 times with respect to the original sample (PANI) as in PANI-CdMoO4, PANI-BiMoO4 and PANI-BaMoO4 respectively. The incorporation of metal molybdates is confirmed by XRD and UV-VIS spectral studies. The XRD studies are also suggested the presence of chemical interaction between polymer chain and incorporated metal molybdates. The antimicrobial activity of the synthesized material PANI and PANI-nanocomposites were tested against four bacteria, Escherichia coli, Staphylococcus aureus, P. aeruginosa and Proteus vulgaris using disc diffusion method. The nanocomposite doped polymer possesses excellent antibacterial property. The results on MB dye degradation showed that PANI-SO4/CdMoO4 photocatalyst, under visible light degraded 80.2 % of MB dye after 180 min. The photo-degradation study, thus, suggests that the light absorption of PANI and catalytic role of CdMoO4 could be coupled for high photo-catalytic functionality. This work opens a new avenue for the design of new modified photo-catalysts with high activity for the large-scale water treatment and other applications.
文章历史:2019年3月20日接收2019年4月29日接受2019年6月4日在线提供2019年6月4日本研究描述了与金属(Cd, Bi, Ba)钼酸盐的二元金属氧化物结合的聚苯胺纳米复合材料的形成过程。以0.1 M苯胺为氧化剂，在100 mL 1 M硫酸中，以0.1 M APS为氧化剂，在50 mg钼酸盐存在或不存在的情况下，在100 mL 1 M硫酸中进行化学聚合，制备聚苯胺及其纳米复合材料。由于金属钼酸盐的掺入，聚合收率提高了。聚合的生长也得到了增强。金属钼酸盐与聚苯胺基体的相互作用增加了聚合物的高导电性，双聚合物链之间的相互作用增加了聚合物的稳定性。金属钼酸盐掺入聚合物基体后，其电导率比原样品(PANI)分别提高了约5倍、4倍和2倍，如PANI- cdmoo4、PANI- bimoo4和PANI- bamoo4。通过XRD和UV-VIS光谱研究证实了金属钼酸盐的掺入。XRD研究表明，聚合物链与掺入的金属钼酸盐之间存在化学相互作用。采用圆盘扩散法测定合成的聚苯胺及其纳米复合材料对大肠杆菌、金黄色葡萄球菌、铜绿假单胞菌和寻常变形杆菌的抑菌活性。纳米复合掺杂聚合物具有优异的抗菌性能。对MB染料的降解结果表明，PANI- so4 /CdMoO4光催化剂在可见光下180 min后对MB染料的降解率为80.2%。因此，光降解研究表明，PANI的光吸收和CdMoO4的催化作用可以耦合在一起，从而获得较高的光催化功能。本研究为设计新型改性高活性光催化剂用于大规模水处理及其他应用开辟了新的途径。

In this present work, we have synthesized transition metal ion nickel doped CdS nanocrystals via coprecipitation method. The objective of this research is to investigate the photocatalytic activity of pure and nickel doped CdS nanocrystals for the degradation of methylene blue and to provide an experimental base for further study and practical application in textile effluent and wastewater treatment processes. Many factors can influence the performance of photocatalytic activity such as phase composition, crystallite size, morphology, and energy gap. The structural and optical properties of as-synthesized materials were studied by XRD, EDAX, SEM, UV, PL, and FTIR. Photocatalytic degradation of methylene blue was performed by using nickel doped CdS nanoparticles in a photoreactor vessel irradiated by visible light from the tungsten lamp (λmax=400 nm).
