Efficient As(III) oxidation and removal by encapsulated BioMnOx@Fh with ferrihydrite-promoted Mn regeneration

Arsenic contamination, particularly the more toxic and mobile As(III), poses a significant threat to water safety. Although manganese oxides can oxidize As(III), their application is often limited by surface passivation and poor regeneration. Here, we synthesized a bio-hybrid material, BioMnOx@Fh, v
