Electrodeposition of nanostructured Bi2MoO6@Bi2MoO6-x homojunction films for the enhanced visible-light-driven photocatalytic degradation of antibiotics

Complex tunable visible-light-driven Aurivillius-phase-based micro- and nanostructured photocatalysts were fabricated following a novel, scalable, easily implemented sequential process based on electrochemical deposition and thermal treatment. Regarding its novelty, electrochemistry was the primary...
