A new TiO_2-β-SiC material for use as photocatalyst

摘要

A new medium surface area TiO_2-β-silicon carbide (β-SiC) material was obtained by the Shape Memory Synthesis (SMS) method in which a pre-shaped high surface area activated charcoal (AC) supporting TiO_2, obtained by a sol-gel process starting from an alkoxide precursor, was attacked by SiO vapor at 1300℃ under dynamic vacuum. A post-synthesis oxidation using the inertness of β-SiC towards oxidation led to the TiO_2-β-SiC material.
