摘要
BIPT-6, a new Ce -based metal-organic framework containing two types of corrosion inhibitors, was designed for complex corrosion protection of AA2024. Synthesized by a facile one-pot solvothermal method, BIPT-6 consists of Ce ions (III/IV) and 2,5-furandicarboxylate ligands. The space group of the novel BIPT-6 was identified as P21/n. Evaluated by EIS, BIPT -6 shows good corrosion inhibition efficiency for AA2024 in 0.05 mol/L NaCl (5∙10 -4 mol/L BIPT-6). Moreover, the corrosion inhibition mechanism of BIPT -6 was i nvestigated. BIPT -6 as a novel MOF with synergetic combination of different types of inhibitors provides a promising approach for smart corrosion protection of aluminum alloys.
