摘要

•The (2 0 0) facet of SrBi2Ta2O9 photocatalyst tends to accumulate electrons while (0 0 1) facet favors the accumulation of photogenerated holes.•High surface facet exposure of (2 0 0) plane in SrBi2Ta2O9 benifits photocatalytic NO removal.•Superoxide radicals play a vital role in photocatalytic NO removal by SrBi2Ta2O9.
