(a) TEM image of mesoporous silica; scale bar 10 nm. (inset: high magnification image indicating the sizes of pores and walls; scale bar 5 nm); (b) TEM image of the mesoporous silica after magnesiothermic reduction; scale bar 10 nm. (inset: high magnification image indicating the (111) lattice of silicon and the (200) lattice of magnesium oxide (MgO); scale bar 5 nm) (c) TEM image of pure silicon nanoparticles; scale bar, 10 nm. (inset: high magnification image of the (111) lattice spacing of crystalline silicon of pure silicon nanoparticles; scale bar 5 nm.) The red arrow indicates the location of a silicon nanoparticle; scale bar 10 nm. (d) High magnification TEM image of pure silicon nanoparticles showing ca. 10 nm size; scale bar 5 nm.
