“…The electron-rich feature of hydroxyl and sulfate ester groups on its surface endow CNs a good colloidal stability in water, which makes it well suitable for the preparation of metal NPs (Benaissi, Johnson, Walsh, & Thielemans, 2010;Hirai, Nakao, & Toshima, 1979;Lin et al, 2011). However, to date, the use of CNs in the biosynthesis of metal NPs is very limited.…”

“…Moreover, the low stability of these colloidal nanoparticles against agglomeration diminishes their reusability performances, which is one of the most important criterias in the heterogeneous catalysis. In this context, the generation of the metal nanoparticles on solid support materials has already been acknowledged for preventing aggregation of active metal nanoparticles and providing high reusability performances in the nitrophenols reduction [37][38][39][40]. Additionally, the use of supported metal nanoparticles as nanocatalyst in the reduction of nitrophenols may provide a kinetic control of the catalytic reaction, whereas it is almost impossible in the catalytic employment of colloidal metal nanoparticles.…”

a b s t r a c tToday, the reduction of nitro aromatics stands a major challenge because of the pollutant and detrimental nature of these compounds. In the present study, we show that nickel(0) nanoparticles (Ni-NP) decorated on electrospun polymeric (polycaprolactone(PCL)/chitosan) nanofibers (Ni-NP/ENF) effectively catalyze the reduction of various nitrophenols (2-nitrophenol, 2,4-dinitrophenol, 2,4,6-trinitrophenol) under mild conditions. Ni-NP/ENF nanocatalyst was reproducibly prepared by deposition-reduction technique. The detailed characterization of these Ni-NP/ENF based nanocatalyst have been performed by using various spectroscopic tools including ICP-OES, P-XRD, XPS, SEM, BFTEM, HRTEM and BFTEM-EDX techniques. The results revealed the formation of well-dispersed nickel(0) NP (d mean = 2.71-2.93 nm) on the surface of electrospun polymeric nanofibers. The catalytic activity of the resulting Ni-NP/ENF was evaluated in the catalytic reduction of nitrophenols in aqueous solution in the presence of sodium borohydride (NaBH 4 ) as reducing agent, in which Ni-NP/ENF nanocatalyst has shown high activity (TOF = 46.2 mol 2-nitrophenol/mol Ni min; 48.2 mol 2,4-dinitrophenol/mol Ni min; 65.6 mol 2,4,6-trinitrophenol/mol Ni min). More importantly, due to the nanofibrous polymeric support, Ni-NP/ENF has shown a flexible characteristics along with reusability property. Testing the catalytic stability of Ni-NP/ENF revealed that this new catalytic material provides high reusability performance (at 3rd reuse 86% for 2-nitrophenol, 83% 2,4-dinitrophenol and 82% 2,4,6-trinitrophenol) for the reduction of nitrophenols even at room temperature and under air. The present study reported here also includes the compilation of wealthy kinetic data for Ni-NP/ENF catalyzed the reduction of nitrophenols in aqueous sodium borohydride solution depending on temperature and type of support material (Al 2 O 3 , C, SiO 2 ) to understand the effect of the support material and determine the activation parameters.

“…Synthesis of platinum nanoparticles using Diopyros kaki leaf extract was reported by (Song et al, 2010) in which he has shown the dependency of size on the reaction temperature and the concentrations of leaf broth and PtCl 6 2-. In another effort, wood nanomaterials in aqueous phase was used to synthesize platinum nanoparticles with controlled shapes and sizes (Lin et al, 2011).…”

A rapid, reproducible single step method is proposed for synthesizing platinum nanoparticles using an invasive weed lantana (Lantana camara, L). The method involves mixing of platinum (VI) solution, lantana leaf extract and ascorbic acid in appropriate concentrations and keeping the mixture at 95°C for 8 min. The collective action of ascorbic acid and leaf extract reduced the chloroplatinic acid to platinum nanoparticles and leaf extract then served the additional purpose of stabilizing the nanoparticles. The resulting nanoparticles have an average size of 35 nm and crystallized in face centred cubic symmetry. The course of the synthesis was trekked by UV-visible spectrophotometry and the characterization of the nanoparticles was done with scanning electron microscopy and confocal laser Raman spectroscopy. Particle size distribution was estimated by dynamic light scattering and the crystal structure was determined by XRD. The purity of the product was checked by EDAX.
