Figure 1. Morphological and physicochemical properties of mesoporous silicon microparticles (MS-MPs).

Figure 1

(A) SEM image of MS-MPs (bar is 200 µm); (B) particle size distribution of the different MS-MP prototypes measured with a particle size analyzer; (C) example of a SEM image of the surface of MS-MPs (corresponding to prototype A, bar is 800 nm); (D) N2 adsorption isotherms, volume adsorbed vs. relative pressure (P/P0), for the different MS-MP prototypes.
