Abstract: SnO2/Na0.9Mg0.45Ti3.55O8 (SnO2/NMTO) heterojunction is synthesized through a hydrothermal technique,and its photocatalytic activity for Rhodamine B (RHB) is investigated.The results show that the photocatalytic activity of SnO2/NMTO is better than NMTO as well as SnO2 in terms of the degradation of RhB.SnO2/NMTO has the best photocatalytic activity when it contains 10% of SnO2.Most of the photogenerated electrons generated during illumination migrate to the interface,which is helpful in prolonging the lifetime of photogenerated electron-hole pairs,thus enhancing the photocatalytic performance of SnO2/NMTO.The results from transient photocurrent responses confirm that photogenerated electron-hole pairs are effectively separated.
