The effect of synthesis temperature and reaction time on the visible-light photocatalytic activity of hierarchical network-like SnIn4S8 microspheres was investigated by the low-temperature co-precipitation strategy.The preparation temperature and reaction time have great influence on the photocatalytic activity of SnIn4S8,and the optimal preparation temperature and reaction time are 70 ℃ and 3 h,respectively.The SnIn4S8 shows good reusability and high stability with no observable decrease of photocatalytic activity in five consecutive cycles.
