Porous silicon prepared from monolithic porous silica glass using a two‐step magnesiothermic reduction

“…[12][13][14] Since then, various types of silicon dioxides with nanometer-size structures have been successfully converted to silicon retaining morphologies similar to those of the original silicon dioxides. [12][13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28] Silicon dioxides can be obtained from natural resources [15][16][17][18][19][20] or by synthesis through various techniques, including the sol-gel and polymer-template methods. [21][22][23][24][25][26][27][28][29][30][31] For the porous silicon prepared from porous silicon dioxides, one of the most attractive uses is as anode materials for lithium-ion batteries.…”

[17][18][19]28,[32][33][34][35][36] We previously reported that we could obtain silicon from pulverized porous silica glass samples, which in turn were prepared from sodium borosilicate glass samples by the heat treatment for phase separation and acid leaching of the borate-rich phase.…”

“…Sandhage and coworkers applied the magnesiothermic reduction to nanostructured silicon dioxide microcrystallites from diatoms and obtained porous silicon with the nanostructure of the microcrystallites 12–14 . Since then, various types of silicon dioxides with nanometer‐size structures have been successfully converted to silicon retaining morphologies similar to those of the original silicon dioxides 12–28 . Silicon dioxides can be obtained from natural resources 15–20 or by synthesis through various techniques, including the sol‐gel and polymer‐template methods 21–31 .…”

Controlled preparation of silicon and magnesium silicide on silica glass substrate through magnesiothermic reduction

“…[2][3][4] Silicon dioxides are reduced to silicon with similar solid-state morphologies. 5 Therefore, various kinds of silicon dioxides with characteristic nano-to microstructures have been used as starting materials for the magnesiothermic reduction including natural [5][6][7][8][9] and synthesized silicon dioxides, 8,[10][11][12][13][14] such as silica diatom frustules, and porous silica glasses and fibers. [15][16][17][18] The obtained silicon has been reported to retain the original structures of the silicon dioxides.…”
