Abstract

A novel mediator Z-scheme photocatalyst, Fe₃O₄/C/UiO-66-NH₂, was designed, synthesized, and characterized using SEM, TEM, FTIR, XRD, EPR, and XPS. Formulas #1 to #7 were examined using dye Rh6G dropwise tests. Carbonization of glucose forms the mediator carbon, which connects two semiconductors, Fe₃O₄ and UiO-66-NH₂, to construct the Z-scheme photocatalyst. Formula #1 generates a composite with photocatalyst activity. The band gap measurements of the constituent semiconductors support the mechanisms for the Rh6G degradation using this novel Z-scheme photocatalyst. The successful synthesis and characterization of the proposed novel Z-scheme confirm the feasibility of the tested design protocol for environmental purposes. © 2023 Elsevier Inc.
