Although photocatalysis research has evolved towards increasingly sophisticated structural regulation and material design, the synergistic enhancement of photocatalysis by multi-component semiconductors and biochar remains underexplored. Here, the authors present a biochar-based g-C3N4/Bi2WO6/Ag3PO4 nanocomposite and apply it to the efficient removal of tetracycline, showing that it forms a double Z-scheme heterojunction that significantly reduces photogenerated carrier recombination.
