Photocatalytic Degradation of Chlorobenzene by in High-Temperature and High-Pressure Water
Figure 6
Schematic energy-level diagram showing photoreduction and photooxidation at the
TiO2-aqueous solution interface. Symbols hν denote
the photon energy of near-UV light, and
the conduction-band electron and positive hole, respectively. a;
H+/H2, b; H+,
O2/H2O, and c; Ag+/Ag:
electronic redox levels. (a) Aqueous solution in ambient conditions;
T = 25°C,
P = 0.1 MPa.
(b) Aqueous solution in hydrothermal conditions;
T = 100–400°C,
P = 30 MPa.
