Electrostatic self-assembly of a AgI/Bi2Ga4O9 p–n junction photocatalyst for boosting superoxide radical generation

A novel AgI/Bi₂Ga₄O₉ p–n junction photocatalyst was synthesized by an electrostatic self-assembly approach. Characterization and DFT calculations show that the formation of the p–n junction greatly boosts the generation of superoxide radicals.
