WitrynaDescription. Also called silica sand or quartz sand, silica is made of silicon dioxide (SiO 2 ). Silicon compounds are the most significant component of the Earth’s crust. Since sand is plentiful, easy to mine and relatively easy to process, it is the primary ore source of silicon. The metamorphic rock, quartzite, is another source. WitrynaN2 - The catalytic activity of Pd core-porous SiO2 shell catalysts (Pd@SiO2) with different Pd particle size was evaluated for the direct synthesis of hydrogen peroxide from hydrogen and oxygen. In the synthesis of palladium nanoparticles, the Pd particle size increased with the decrease of the ratio of polyvinylpyrrolidone (PVP) to Pd.
