What is Photocatalytic H2 evolution of porous silicon derived from magnesiothermic reduction of mesoporous SiO2 about?
In this work, porous silicon (PSi) was synthesized by magnesiothermic reduction of mesoporous SiO 2 (MCM-41) and its photocatalytic hydrogen evolution performance was investigated. The unique mesoporous structure of PSi expands the band gap of silicon and shifts its conduction band to a more negative position. As a result, excellent photocatalytic water splitting efficiency of 604.7 mmol h À1 g À1 under visible-light radiation is recorded for the synthesized PSi photocatalysts without loading noble metal cocatalysts. This study presented a promising visible light response photocatalysts for the generation green renewable hydrogen energy basing on PSi material deriving from simple magnesiothermic reduction of mesoporous SiO 2 .
