摘要	A direct Z-scheme bismuth iodide/bismuth niobate (BiOI/BiNbO) heterojunction photocatalysts with a different molar ratio of Bi/Nb were prepared. The structural and photoelectrical properties of these as-prepared samples were investigated, photocatalytic activity and different effect factors were evaluated. The experiment results indicated that the highest RhB degradation efficiency was that of the sample with Bi/Nb = 0.7, bringing a lower interface resistance that facilitate the separation and transportation of photogenerated carrier. Furthermore, active species trapping experiments suggested that center dot OH was the most contributor responsible for the RhB photocatalytic process. The photodegradation mechanism and a reasonable degradation pathway were further proposed by DFT theoretical calculation.
