Bandgap engineering of hierarchical network-like SnIn4S8 microspheres through preparation temperature for excellent photocatalytic performance and high stability

摘要

The effect of synthesis temperature and reaction time on the visible-light photocatalytic activity of hierarchical network-like SnInsub4/subSsub8/sub microspheres was investigated by the low-temperature co-precipitation strategy. The preparation temperature and reaction time have great influence on the photocatalytic activity of SnInsub4/subSsub8/sub, and the optimal preparation temperature and reaction time are 70?°C and 3?h, respectively. The SnInsub4/subSsub8/sub shows good reusability and high stability with no observable decrease of photocatalytic activity in five consecutive cycles.
