Before revision: However, at higher temperatures (~>80 °C), hydrogen radicals react with siloxyl radicals, preventing the generation of H2 by this mechanism: ≡Si–O• + H• → ≡Si–O–H 2H• → H2 Oxidant Generation When oxygen reacts with silicon or oxygen radicals at the surface of crushed rocks, it can chemically adsorb to the surface: ≡Si• + O2 → ≡Si–O–O• ≡Si–O• + O2 → ≡Si–O–O–O• These oxygen radicals can then generate oxidants such as hydroxyl radicals and hydrogen peroxide: ≡Si–O–O• + H2O → ≡Si–O–O–H + •OH 2•OH → H2O2 Additionally, oxidants may be generated in the absence of oxygen at high temperatures: ≡Si–O• + H2O → ≡Si–O–H + •OH 2•OH → H2O2 H2O2 breaks down naturally in environments to form water and hydrogen peroxide : 2H2O2 → 2H2O + O2 Industry applications Fundamentals and applications ranging from nano materials to technology have been reviewed.
