The invention discloses a method for preparing ti-based nanometer lead dioxide, belonging to the field of inorganic nano-material synthesis. The method comprises the following steps of polishing the surface of a titanium sheet; preparing a ti-based aluminum membrane in an organic solution through an electro-deposition method, wherein an electroplate solution adopts the nonaqueous solution of an AlCl3-LiAlH4 system, and the solvent adopts tetrahydrofuran and benzene; then preparing a ti-based AAO (anodic aluminum oxide) template in an oxalic acid solution through a two-step anodic oxidation method, and removing a barrier layer through a certain mass fraction of phosphoric acid so as to expand a duct to reach a titanium substrate; finally, depositing PbO2 nano particles into the AAO template by the electro-deposition method, removing the rest aluminum membrane with a certain mass fraction of sodium hydroxide solution, and obtaining the ti-based nanometer lead dioxide. The method has low requirement on equipment, has low cost, and can be applied to fields such as gas sensors, electrochemistry electrodes, photoelectric devices and the like.

The invention discloses a preparation method of a ternary modified titanium electrode. The preparation method includes the steps: grinding ternary bases, soaking the grinded ternary bases into oxalatesolution, performing water bath acid corrosion for 1 hour at the temperature of 90 DEG C, and cleaning and storing the ternary bases for standby application; taking SnCl2*2H2O to place the SnCl2*2H2Ointo a container, sequentially adding n-butyl alcohol and Ti(OC4H9)4 solution into the container, uniformly mixing materials, and dissolving the mixed materials under ultrasonic conditions to obtainSn/Ti coating liquid; coating the surface of a pretreated titanium sheet with the Sn/Ti coating liquid, and drying the titanium sheet; soaking the dried titanium sheet into Pb(NO3)2 solution for 30-50seconds, taking out the soaked titanium sheet to dry the titanium sheet, firing the titanium sheet for 1-1.5 hours at the temperature of 300-600 DEG C, and cooling the fired titanium sheet to reach the indoor temperature to obtain the ternary modified titanium electrode. Good integrity is kept after a PbO2 active layer is repeatedly used by the ternary modified titanium electrode, the electrode is durable, and aniline dye wastewater is efficiently degraded by the electrode.
