摘要

•Natural formed anodic film has dual effects on reducing Pb-contamination release.•Dense and reticular structure of film possessed better physical protection for Pb.•Anodic film with Mn3+ and oxygen vacancy accelerated OER and inhibit MOR.•Dynamic mechanism was deduced by experimental results and DFT calculations.
