UV-visible absorption measurements of re-dispersible silver particles that were obtained by reduction of silver myristrate (product-IV) and silver nitrate (product-I) showed surface plasmon resonance absorption peak at 400 nm. The powder XRD pattern of fcc zero-valent silver resulted in diameters in the range of about 25-30 nm. TEM analysis showed particle diameter similar to that was observed by the XRD. FTIR spectroscopy revealed that the organics from the carboxylate group are retained by the nano-particles in case of product-IV however, presence of TOP is observed in product-I. It is found that when silver nitrate is reduced by TOP, spherical silver nano-particles with poor redispersity are formed but extended heating results in formation of long silver rods of micrometer size however, the re-dispersible nano-particles are easily formed when silver carboxylates are reduced by TOP.</p>10aChemical synthesis10aNanocrystalline10anoble metal10aXRD1 aCharan, Shobhit1 aSingh, Narendra1 aKhanna, P., K.1 aPatil, K., R.  uhttps://library.ncl.res.in/content/direct-synthesis-nanocrystalline-silver-reaction-between-silver-carboxylates-and-n-002051nas a2200277   4500008004100000022001400041245009600055210006900151260008600220300001200306490000700318520111200325653001001437653002301447653001601470653001601486653002101502100001901523700001401542700001701556700001801573700002001591700001801611700001701629856012701646       2007                        eng d  a1553-317400aOne-step preparation of nanosized Ag-PdCo-powder and its alloy formation at low temperature0 aOnestep preparation of nanosized AgPdCopowder and its alloy form  a325 CHESTNUT ST, SUITE 800, PHILADELPHIA, PA 19106 USAbTAYLOR & FRANCIS INCcSEP  a531-5390 v373 a<p>Nano-sized silver-palladium co-powder has been synthesized from silver nitrate-palladium chloride by wet chemical method. The present experimental conditions are applied for the first time for Ag-Pd co-powders wherein sodium formaldehyde sulfoxylate (SFS) has been used as an external reducing agent to simultaneously reduce respective metal salts. SFS reduces the metal salts at room temperature thus prevents formation of bigger particles of the respective metals in co-powder. Powder X-ray diffraction measurements ( XRD) and Transmission electron microscopy ( TEM) suggest the formation of nano-sized Ag-Pd co-powder with particle diameter in the range of about 25 nm. SEM shows that the powder morphology changes with temperature. Heat treatment of 90: 10 (Ag:Pd) composition showed shift in XRD peaks indicating alloy formation of Ag/Pd at lower temperature. Thick-films generated by use of the co-powder resulted in Ag/Pd alloy at about 500 degrees C as confirmed by the XRD. Thermal analysis showed that Ag/Pd co-powders initially gain the weight due to oxidation followed by the weight loss.</p>10aalloy10aChemical synthesis10anano-powder10anoble metal10aTransition Metal1 aKhanna, P., K.1 aSingh, N.1 aKulkarni, D.1 aMarimuthu, R.1 aCharan, Shobhit1 aPatil, K., R.1 aJain, G., H.  uhttps://library.ncl.res.in/content/one-step-preparation-nanosized-ag-pdco-powder-and-its-alloy-formation-low-temperature-0
