Abstract A novel and highly promising Ag 2 S-P2MA nanoribbon photocathodes are synthesized using a single-step technique based on 2-mercaptoaniline oxidation with (NH 4 ) S O 8 AgNO 3 . This process yields polymer composites morphologies, typically 150 nm wide ranging from 500 to 1,000 in length. These nanoribbons exhibit excellent absorbance across the entire optical spectrum up 780 nm.
