Preparation And Application Of Macroporous Ato/Sio2 Electrode In Electrochemical Degradation Of 4-Chlorophenol, Zhang-Lin Chai, Rui-Feng Zhang, Tong-Hu Xiao, Yun-Xiao Liang
Journal of Electrochemistry
The macroporous ATO/SiO2 materials were prepared through multiple steps of hydrolysis deposition in ethylene glycol and acetonitrile mixed solutions of SnCl2/SbCl3 and subsequent calcination at high temperature. The structures of the obtained materials were characterized by means of SEM and XRD. The results showed that the nano-ATO chemically deposited on the SiO2 support underwent well-controlled aggregation and recrystallization to form a sandwich structure (ATO-SiO2-ATO). Through four times loading of ATO the volume resistivity and the specific surface area reached 10 ??cm and 77 m2?g-1, respectively. The oxygen evolution potential on macroporous ATO/SiO2 anode was 2.5 V in acidic condition and …
