摘　　要：纳米银由于体积小、比表面积大及物理和化学性能独特而受到广泛关注[1,2].研究结果表明,纳米银的光学、电学和催化活性与粒子的粒径、形貌和结构之间存在强烈的依赖关系[3].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.
