Abstract:

The operable factors, including concentration/gas velocity of target, light transmission, relative humidity and reactor types of the heterogeneous photocatalytic degradation of VOCs, were discussed in this paper. The photocatalysis and photocatalytic degradation kinetics/mechanisms were described, and its limitation in both photon transfer and mass transfer were included. The important issues in future design and research was prospected.
