Surface-sulfurized Ag2O nanoparticles with stable full-solar-spectrum photocatalytic activity

The full-solar-spectrum photocatalytic activity of Ag2O/Ag2S2O7 heterostructure is demonstrated. Ag2O/Ag2S2O7 heterostructures can not only keep NIR photocatalytic activity, but also enhance UV and Vis photocatalytic activity of Ag2O. Most importantly, the stability of Ag2O/Ag2S2O7 heterostructures is dramatically improved.
