▎ 摘　　要

NOVELTY - Photoelectric energy storage material comprises tungsten trioxide/reduced graphene oxide nanorod composite and titanium dioxide powder in the mass ratio of 1:1. USE - The photoelectric energy storage material and electrode is useful for anti-corrosion protective film for suppressing and inhibiting metal corrosion and protecting in dark state (all claimed). ADVANTAGE - The material: has good continuous cathode protection function induced potential and photo generated current density in the dark after illumination; and method is simple, and solves problem of continuous cathode protection under cloudy and dark conditions. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) preparing storage material, comprising (i) adding graphene oxide to ethanol to form a stable dispersion, (ii) dissolving tungsten hexachloride and zinc chloride with a mass ratio of 8:1-10:1 in a mixed solution of ethanol and polyethylene glycol under magnetic stirring, (iii) mixing the solutions obtained in step (i) and (ii) to obtain homogeneous solution under magnetic stirring, and heating at 170-190 degrees C for 22-26 hours to obtain blue precipitate tungsten trioxide/reduced graphene oxide nanorod composites, and (iv) taking titanium dioxide-tungsten trioxide/reduced graphene oxide composite photoelectric energy storage material; and (2) tungsten trioxide/reduced graphene oxide composite photoelectric energy storage electrode is obtaioned by uniformly grinding titanium dioxide tungsten trioxide/reduced graphene oxide composite photoelectric energy storage material tungsten trioxide/reduced graphene oxide nanorod composite and titanium dioxide powder coating on the surface of conductive substrate with an equal proportion of area.
