contactOxidation of silicon. Silicon's surface has a high affinity for oxygen and thus an oxide layer rapidly forms upon exposure to the atmosphere. The chemical reactions which describe this formation are: (7.11.1) Si (s) + O 2 (g) → SiO 2 (s) (7.11.2) Si (s) + 2 H 2 O (g) → SiO 2 (s) + 2 H 2 (g) In the first reaction a dry process is utilized ...
contactThese oxidation reactions are considerably improved by using phase-transfer catalysis (PTC) when the catalyst is an anionic oxo complex. PTC enhances the reactivity of transition-metal oxide anions by the introduction of a large organic cation such as R 4 N + (with long alkyl arms for R). This organic cation, the phase-transfer catalyst ...
