Abstract

The present invention relates to a Z-type heterojunction photoanode film used for the photocathode protection of a reinforcing bar, the preparation method thereof and a method for the corrosion inhibition of mental materials from concrete structures in marine engineering by using the Z-type heterojunction photoanode film used for the photocathode protection of a reinforcing bar. The preparation method includes steps of preparing FeOon the conducting surface of a clean conductive substrate through the hydrothermal process, preparing FeO-PANI composite photoanode film by depositing polyaniline on the surface of FeOthrough the electrochemical synthesis and preparing Ru-FeO-PANI composite photoanode film on the surface of the FeO-PANI composite photoanode film through the in situ chemical reduction method. The technical solution in the present invention can achieve highly effective photocathode protection of a reinforcing bar from concretes in marine engineering and improve the durability of concrete structures in marine engineering.
