Abstract: Solar energy has drawn considerable attentions in environmental applications in recent years. The conventional water treatment processes are normally costly and energy-consuming. Developing solar energy-powered water treatment technology will be a promising solution. Our recent work involves two different types of solar water treatment processes. One is photocatalytic decomposition of pollutant molecules, and the other one is photothermal disinfection process. In photocatalytic process, developing novel broadspectrum-responsive semiconductor materials, constructing composite photocatalysts and inventing efficient synthetic approaches are investigated, respectively. In addition, we studied plasmonic-enabled photothermal disinfection process.
