چکیده
Triangular gold nanoplates in CTAB solution were selectively precipitated on a glass wall in ambient conditions and the nanoplates could be easily recovered by a brief sonication.

One-pot synthesis of triangular gold nanoplates allowing broad and fine tuning of edge length.
A photocatalytic approach was used to synthesize triangular nanoplates in aqueous solution. The synthesis is based on the reduction of a gold salt using a tin(iv) porphyrin as photocatalyst, cetyltrimethylammonium bromide (CTAB) as a stabilizing agent, and triethanolamine (TEA) as the final electron donor. The average edge length of the triangular nanoplates can be easily changed in the range 4...
متن کاملHigh-yield synthesis of triangular gold nanoplates with improved shape uniformity, tunable edge length and thickness.
We report the synthesis of uniform triangular gold nanoplates by a modified seeded growth method. The concentration of cetyltrimethylammonium bromide (CTAB) in the growth solution and the time interval between multiple steps of growth were important factors which determined the formation of uniform triangular Au nanoplates. In addition, by further isotropic overgrowth, the thickness of triangul...
متن کاملShape separation of colloidal gold nanoparticles through salt-triggered selective precipitation.
Highly effective separation of colloidal gold nanorods/nanoplates from co-produced isotropic nanoparticles has been achieved by selective precipitation triggered by salt.
متن کاملFacile synthesis of concave gold nanoplates in hexagonal liquid crystal made of SDS/water system.
Concave gold nanoplates are obtained in hexagonal liquid crystal (LLC) made of SDS (sodium dodecyl sulfate)/glycine/HAuCl(4) aqueous solution system where glycine plays the key role. All plates are single-crystals, characterized by {111} facets, with concave centers of regular hexagonal or triangular shapes, and with better electrocatalytic activity than gold nanoplates.
متن کاملGold Nanoplates for a Localized Surface Plasmon Resonance-Based Boric Acid Sensor
Localized surface plasmon resonance (LSPR) properties of metallic nanostructures, such as gold, are very sensitive to the dielectric environment of the material, which can simply be adjusted by changing its shape and size through modification of the synthesizing process. Thus, these unique properties are very promising, particularly for the detection of various types of chemicals, for example b...
