Abstrakt

Using a magnesiothermic reduction process, the successful conversion of hierarchically organized meso/macroporous silica monoliths to self-supporting macroporous silicon networks comprising interparticle mesoporosity has been demonstrated. By careful variation of reaction time and temperature, the final network structure can be controlled to a large degree. Scanning and transmission electron microscopy images indicate that the cellular silicon structure is built up from aggregated 1-15 nm sized crystalline silicon particles aggregated to struts that form macropores of approximately 2 mu m diameter.
