Abstract
We report a systematic study of the chemical properties of porous silicon as a moderate reducing agent and a nano-structure template for the reductive formation of nano-metal cluster aggregates. This study investigates the consequences of the interaction of silver ions in aqueous solution with porous silicon. The nature of the redox reaction, especially the role of surface hydrogen and silicon atoms, is established through the study of the morphology, structure, and electronic and optical properties of Ag on porous silicon. The specimens were characterized with SEM and X-ray absorption fine structure (XAFS) spectroscopy using synchrotron radiation
