A novel n-p heterojunction Bi₂S₃/ZnCo₂O₄ photocatalyst for boosting visible-light-driven photocatalytic performance toward indigo carmine.

ABSTRACT: An innovative p-n heterojunction Bi₂S₃/ZnCo₂O₄ composite was first fabricated via a two-step co-precipitation and hydrothermal method. By controlling the weight amount of Na₂S and Bi(NO₃)₃ precursor, different heterogeneous xBi₂S₃/ZnCo₂O₄ were synthesized (x = 0, 2, 6, 12, and 20). The p-n heterojunction Bi₂S₃/ZnCo₂O₄ was characterized by structural, optical, and photochemical properties and the photocatalyst decoloration of indigo carmine. Mott-Schottky plots proved a heterojunction formed between n-Bi₂S₃ and p-ZnCo₂O₄. Furthermore, the investigation of the photo
