Based on a brief review of semiconductor photocatalytic mechanism and researches in the past 30 years on TiO2 heterogeneous photocatalysis, this paper emphasizes that the natural vanadiferous rutile and its modified products, which have not been investigated by either Chinese or foreign research groups, degrade halogenated organic contaminants. By means of grinding, heating in situ, heating, quenching and electron irradiation, the natural rutile could be modified.

The conducting wall in micro-tube preheats the inlet mixture by axial heat transfer. The existence of conducting wall will help to reach full reaction in the micro-tube. As the inlet velocity increases, both the existence of the surface catalytic combustion and the gas phase combustion become the limiting factors on combustion. Wall material and equivalence ratio of hydrogen/air mixture have important influence on catalytic combustion of hydrogen.
