Functionalization of silicon has become an interesting research topic due to the excellent combination of properties of functionalized Silicon that could be used in many applications, e.g. in energy conversion based on its good thermoelectric properties. One type of functionalized silicon is its nanoporous form that can be produced by subtractive or additive manufacturing at the nanoscale. However, due to the high cost, the search for cost efficient technologies is currently under way. One promising route is offered by Metallothermic Reduction Reaction (MRR) from silica. Here we report the characterization of nanoporous Silicon produced from diatomite earth via Magnesiothermic Reduction Reaction. The methods used include Raman Spectroscopy, Scanning Electron Microscopy and X-ray Diffraction.
