Abstract: Silver dendritic structures were electroless deposited on the top of silicon pyramids which were obtained by anisotropic etch in KOH solution. More details of the silver dendritic structures were observed by scanning electronic microscopy (SEM) and X-ray diffraction (XRD) were performed to further investigate the silver dendritic structures; the peaks observed are consistent with the JCPDS card (JCPDS No. 420783). Furthermore, the formation mechanism of silver dendritic structures has been clarified base on the model of galvanic cell and the diffusion-limited aggregation (DLA). The results show that the effect of point plays an important role in the selective deposition of silver dendritic structures. The 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.

Key words: silver dendritic structures, selective electroless deposition, catalytic property
