In this paper, we successfully fabricate a stable and highly efficient direct sunlight plasmonic photocatalyst Ag−AgBr through a facile hydrothermal and subsequently sunlight-induced route. The diffuse reflectance spectra of Ag−AgBr indicate strong absorption in both UV and visible light region. The...
