Bimetallic Core-Shell Nanorings

What is it about?

Results are one-pot approach for synthesis of bimetallic core-shell nanorings at room temperature using ascorbic acid. We have addressed the role of ascorbic acid for the first time which will certainly add within the context of the existing scientific literature. In-depth investigation using transmission electron microscopy and associated techniques reveals that single crystalline Ag nanoparticles led to the formation of continuous Au nanorings with single crystalline walls and the voids spaces

Why is it important?

Despite the significant amount of work has already been carried out on noble metal core-shell nanostructures following different synthetic method like: photo-induced process, thermal process, sonochemical process, a very little has been done on core-shell nanoring following the solution method at room temperature. In this article we have presented the room temperature synthesis of Au-ring in presence and absence of ascorbic acid. Au-core and Ag-shell nanorings produced using continuous Au-ring a
