Abstract

Noble metal nanoparticles on silicon wafers can form microstructures not only by electroless deposition of themselves but also by their catalytic activity for etching of silicon and initiation of electroless metal deposition. We fabricate various noble metal nanoparticles on silicon by electroless displacement deposition and apply them to metal-assisted hydrofluoric acid (HF) etching of silicon autocatalytic electroless deposition of metal on silicon, solar-hydrogen production using photoelectrochemical cells, and noble metal recovery from waste electrical and electronic equipment. In this presentation, noble metal nanoparticles and nanostructures formed on silicon surfaces by these processes are described.
