Selective deposition of silver dendritic structures and its catalytic property

The fabrication of different silver nanostructures is important for their applications. Herein, silver dendritic nanostructures were electroless deposited on the top of silicon pyramids created by anisotropic etch in KOH solution. The formation mechanism of silver dendritic nanostructures was clarified based on the investigation with scanning electronic microscopy (SEM). The results show that silver dendritic structures can be used for catalytic reduction of 4-nitroaniline and this structures might be used for the micro-functional devices in the future.
