Title:
INDIUM-DOPED TITANIUM-BASED LEAD DIOXIDE ELECTRODE, AND MANUFACTURING METHOD THEREOF AND APPLICATION OF SAME
Document Type and Number:
WIPO Patent Application WO/2018/023912
Kind Code:
A1
Abstract:
An indium (In)-doped titanium-based lead dioxide electrode, and manufacturing method thereof, and an application of same in degradation treatment of highly concentrated pharmaceutical wastewater with low biodegradability. The electrode uses titanium as the matrix, and comprises an antimony tin oxide base layer, an α-PbO2 middle layer, and an In-doped, fluoride-containing β-PbO2 active layer, wherein the layers are coated onto a titanium matrix in that order. A structural design and surface doping of the electrode are used to modify the lead dioxide electrode. By adding the post-transition metal In and a fluoride polymer resin, micro-particle dispersion of PbO2 on the surface of the electrode becomes more compact and uniform, greatly improving a surface structure and property of the electrode and reducing an internal stress between the PbO2 active layer and the titanium matrix. The final electrode therefore has a higher oxygen evolution potential and electrochemical stability, effectively extending the service life of the electrode. The electrode has excellent catalytic performance, long service life, and strong potential applicability, and is easy to manufacture. The invention has great market prospects.
