“…Chemical reduction methods are commonly used to synthesize the silver nanoparticles. Typical reducing agents are polyols, [18,19] NaBH 4 , [20][21][22] N 2 H 4 , [23] sodium citrate, [24] polymeric thiols, [25] triton X 100, [26] and amino acids. [27][28][29][30] Polyvinyl-pyrrolidone and polyvinyl alcohol are biologically friendly polymers, as it is water soluble, and has extremely low cytotoxicity.…”

A simple one-step rapid green microwave irradiation method is described for the synthesis of silver nanospheres (Ag NS) using threonine as a reducing and polyvinyl-pyrrolidone as a capping agent. UV-Visible spectrum and photoluminescence spectrum confirmed the formation of Ag NS. High-resolution transmission electron microscopy and high-resolution scanning electron microscopy was used to find the morphology of the synthesized sample, which has sphere-like morphology. The elemental composition of the Ag NS was determined by energy dispersive X-ray analysis. Antibacterial experiments showed that the prepared Ag NS had better antibacterial activities than silver nitrate in the same concentration.

Alcohol-Selective Oxidation in Water under Mild Conditions via a Novel Approach to Hybrid Composite Photocatalysts

et al. 2015

View full text Add to dashboard Cite

The oxidation of alcohols to carbonyl compounds in a clean fashion (i.e., with water as a solvent or under solvent‐free conditions, and using O2 or H2O2 as the primary oxidant) is the subject of considerable research efforts. A new approach for the selective oxidation of soluble aromatic alcohols in water under mild conditions via a novel composite photocatalyst has been developed. The catalyst is synthesized by grafting 4‐(4‐(4‐hydroxyphenylimino)cyclohexa‐2,5dienylideneamino)phenol and silver nanoparticles onto the surface of moderately crystalline titanium dioxide. The titanium dioxide‐based composite was first extensively characterized and then employed in the catalytic oxidation of 4‐methoxybenzyl alcohol to 4‐methoxybenzaldehyde under UV irradiation in water at room temperature. The corresponding aldehyde was obtained with unprecedented high selectivity (up to 86 %). The method is general and opens the route to fabrication of photocatalytic composites based on titanium dioxide functionalized with shuttle organic molecules and metal nanoparticles for a variety of oxidative conversions.
