9.1 Introduction

The open porous structure and very large specific surface area of porous silicon (PSi) have driven scientists to introduce different foreign substances into its pores to fabricate PSi-based composite and hybrid materials (Hérino et al. 1997; Hérino 2000). Under this approach, PSi plays a role of host material, which receives foreign substances as “guests”: metals, semiconductors, and carbon-containing materials (polymers, fullerenes, carbon nanotubes, and graphene). Nowadays in most cases, PSi is considered a template, that ...
