Here, solar energy is readily available in most climates and can be used for water purification. However, solar disinfection of drinking water (SODIS) mostly relies on ultraviolet light, which represents only 4% of total solar energy, and this leads to slow treatment speed. The development of new materials that can harvest visible light for water disinfection, and speed up solar water purification, is therefore highly desirable. Here, we show that few-layered vertically aligned MoS₂ (FLV-MoS₂) films can be used to harvest the whole spectrum of visible light (~ 50% of solar energy) and achieve highly efficient water disinfection. The bandgap of MoS₂ was increased from 1.3 eV to 1.55 eV by decreasing the domain size, which allowed the FLV-MoS₂ to generate reactive oxygen species (ROS) for bacterial inactivation in water. The FLV-MoS₂ showed ~15 times better log inactivation efficiency of indicator bacteria compared to bulk MoS₂, and much faster inactivation of bacteria under both visible light and sunlight illumination compared to widely used TiO₂. Moreover, by using a 5 nm copper film on top of the FLV-MoS₂ as a catalyst to facilitate electron-hole pair separation and promote the generation of ROS, the disinfection rate was further increased 6 fold. With our approach, we achieved water disinfection of >99.999% inactivation of bacteria in 20 minutes with a small amount of material (1.6 mg/L) under simulated visible light.
