Abstract

A facile and rapid microwave-assisted method was proposed to prepare tin disulfides (SnS₂) for use as visible-light responsive photocatalysts with narrow band gap (~2.1eV). The photocatalytic activity of SnS₂ was evaluated by photodegradation of methylene orange (MO) under visible light irradiation (455nm of LED lamp). SnS₂-M show enhanced photocatalytic activities compared to SnS₂-A and conventional TiO₂, and the mineralization ratio of MO by SnS₂-M showed highest value (0.025) as compared to literature data. To confirm the photoreduction mechanism, Au or Ag dots as inhibitor for direct reduction of MO were decorated on the SnS₂ surface.
