摘要

In this study, Zn2SnO4 nanoparticles with different sizes are successfully synthesized by a very convenient hydrothermal process. To sufficiently characterize the as-synthesized Zn2SnO4 nanoparticles, XRD, FE-SEM, TEM, UV and BET analyses are carried out. Moreover, the photocurrent response and photocatalytic activity properties of various Zn2SnO4 nanoparticles have been studied. The results indicate that the photocurrent response and photodegradation efficiency behavior of the 3.3 nm Zn2SnO4 nanoparticles are significantly superior to that of the 4.2 nm and 6.2 nm nanoparticles. It is due to small particle size effects with large surface-to-volume ratios, which can increase the number of active surface sites.
