Nanoporous Silicon Materials Achieved by Electrochemical Method and Applications

Abstract

Nanoporous materials have attracted extremely intense scientific attraction since the photoluminescence discovery at room temperature because of the quantum confinement effects. It is well known that in addition to the superior photoluminescence, nanoporous silicon materials prepared by the electrochemical method are promising materials for applications in catalysis, chemical, energy storage and biological sensing, due to its high porosity, modifiable surface, biocompatibility and biodegradability, which comprise with tunable optical porous Si structure and the applications such as biosensing, in vivo imaging, gas sensing and solar cells. Therefore, the facile electrochemical methods employed to synthesize the nanoporous materials are marked, especially for nanoporous silicon materials aim to provide the crucial information about the relevant techniques to consider the eco-friendly developments for the future environmental risks to diminish.
