Enhanced performance for Rhodamine B degradation over SnO2/BiOBr photocatalyst

Hong-jian Zhao et al.

Summary: A SnO2/BiOBr photocatalyst with broad-spectrum response was successfully constructed via in situ hydrothermal method, where SnO2 was anchored on the surface of BiOBr sheets by acidolysis of Na2SnO3 in the stock solution producing BiOBr. The photocatalytic degradation activity of Rhodamine B (RhB) under visible light-emitting diode irradiation was further improved by coupling a 7% amount of SnO2. The enhanced performance can be attributed to the excellent adsorption abilities for RhB, broadened visible light response, and efficient transfer of photogenerated electrons from BiOBr to SnO2.
