Photo-assisted bismuth ferrite/manganese dioxide/nickel foam composites activating PMS for degradation of enrofloxacin in water

A green catalyst and sensor: band engineering of Bi2Fe4O9-based S-scheme p–n/n homo-heterojunction for detection and degradation of cytotoxic drug

“…This effective reduction of the band gap values could be attributed to the introduction of external energy levels with the addition of TS powder. 34 A decrease in the band gap value leads to a higher number of electrons in the conduction band, which eventually decreases the electron–hole recombination process and enhances the catalysis reaction.…”
