Abstract
The development of coupled semiconductor photocatalysts makes a significant advancement in catalytic functional materials. A new heterostructured Bi2O3–ZnO, synthesized by a simple hydrothermal–thermal decomposition method, exhibited higher photocatalytic activity for the degradation of Acid Black 1 (AB 1) under UV light than pure ZnO, Bi2O3, and commercial Degussa P25. X-ray powder diffraction analysis reveals that the as-synthesized product has the monoclinic lattice phase of Bi2O3 and the hexagonal wurtzite phase of ZnO. HR-SEM images show that Bi2O3–ZnO has an ordered mixture of nanofiber and nanochain structures. This heterostructured Bi2O3–ZnO has increased UV absorption when compared with ZnO. The enhanced photocatalytic activity of Bi2O3–ZnO is attributed to the low recombination rates of photoinduced electron–hole pairs, caused by the vectorial transfer of electrons and holes between ZnO and Bi2O3. Higher efficiency at neutral pH 7 and reusability in the degradation of AB 1 makes Bi2O3–ZnO, a pro...
