Abstract

In this research, using powder technology manufacturing is as a pioneering, low cost, a simple and safe method for the fabrication of nano-porous silicon (NPS-powder). It's attractive carriers for targeted in several research fields. It's prepared using a combination of alkali chemical etching process and ultra-sonication technique; through the utilization of commercial silicon powder; with high yield efficiency (81.43%). Several 3D-NPS-shapes (nanorods array, nanosheets, and nanoclusters) are fabricated. It's a mixture of microporous and mesoporous silicon powder {pore size (28-140 nm)}. The main factors which affect the production of NPS-powder are (KOHconc.), sonication time, separation process and drying velocity.
