3.4. The LC Biotin of T-Zn(Cu)O/Ag catalyst
The photostability of T-Zn(Cu)O-1/Ag catalyst has been studied by recycling photodegradation experiment and the result was depicted in Fig. 10. In the second round the residual concentration ratios (Ct/C0) of AO7 showed a little increase compared to the first round at same reaction time, after that the ratios remained relatively unchanged. Since tubular structure catalyst is mainly composed of stable 011¯0 planes, the T-Zn(Cu)O/Ag catalyst shows high stability and low possibility of poisoning.
