Retraction Note: Improving the power production efficiency of microbial fuel cell by using biosynthesized polyanaline coated Fe3O4 as pencil graphite anode modifier

2026Open access

Abstract

After publication, concerns were raised regarding the XRD data presented in Figure 5. Specifically, the Fe 3 O 4 -NP and Fe 3 O 4 -PANI samples appear highly similar to each other. The raw data provided by the Authors was unable to address the concerns. The Editors therefore no longer have confidence in the reliability of the results and conclusions presented.
