Study on hydrogen reactivity with surface chemical species of nanocrystalline porous silicon

Influence of palladium particles impregnation on hydrogen behavior in meso-porous silicon

“…Since the surface of PS formed by electrochemical etching is covered with SiH x silane groups, there is a potential application of this material as a solid state hydrogen reservoir. The most widely used methods for H 2 production from PS are heating [14,15], photodesorption [16] and chemical reaction with water [15,[17][18][19]. The creation of a palladium/silicon meso-porous composite is expected to modify the hydrogen desorption properties of PS.…”
