Description
Summary:Coreshell‐like Ag2O/Ag2CO3 nanoheterostructures with tailored interface are fabricated by a facile, low‐cost and one‐step phase transformation method. The unique bandgap structure of the Ag2O/Ag2CO3 exhibits high separation efficiency of photogenerated electrons and holes, which effectively protects the Ag2CO3 semiconductor to avoid its photoreduction and gives rise to high activity and stability in degradation of the typical water pollutants.
