Wicker-shaped silver

WICKER-SHAPED SILVER PARTICLES PREPARED BY EXTRACTION INTERFACE REDUCTION... 

Wicker-shaped silver partieles are obtained by interface reduction during the extraction process. The primary amine N1923 is used as extractant and reductant of silver. The silver particles were characterized by X-ray diffraction and transmission electron microscopy. It is shown that silver particles are wicker-shaped and uniformly dispersed and the wicker-shaped silver is composed by spherical particles of silver average diameter ca. lOnm. 

It is well known that silver (I) can be reduced to the metallic state with various organic substances and thus agitation of silver (I) with some extractants may reduce it. In the literature, the solvent extraction-reduction process possesses metallic ions were extracted form an aqueous solution to organic solvents and then the ions were reduced in the organic phase by reductant or radiation. In this work, we report a new strategy to prepare wicker-shaped silver. The primary amine N1923 is used as extractant and reductant. 

In summary, the wicker-shape silver is prepared by extraction-reduction. In the process of the preparation, the primary amine N1923 act as the reductant, extractant and template and the conditions of the extractants are also important.
