Energy storage type TiO2/CNX/WO3 composite material photo-anode and preparation method thereof

The invention discloses an energy storage type TiO2/CNX/WO3 composite material photo-anode and a preparation method thereof. The preparation method comprises the following steps: preparing a WO3 nanorod by a hydrothermal method; adding the WO3 nanorod and an anionic surfactant into water, carrying out ultrasonic treatment, adding pyrrole, stirring, dropwise adding an initiator solution under an ice bath condition, stirring, and reacting to obtain a WO3/PPy compound; adding the WO3/PPy compound and an anionic surfactant into an alcoholic solution, carrying out ultrasonic treatment, stirring, adding tetrabutyl titanate, glacial acetic acid and acetone, dropwise adding an aqueous solution of alcohol, transferring into a hydrothermal reaction kettle, and carrying out a reaction, so as to obtain a precursor TiO2/PPy/WO3 compound after the hydrothermal reaction; and the precursor TiO2/PPy/WO3 compound is loaded on the conductive substrate. The excellent continuous photoelectric cathode protection performance of TiO
