Atrazine (ATZ) is a highly toxic chlorine-containing aromatic structural triazine endocrine disruptor. Due to its chemical stability and electrochemical inertness, it is of great challenge and significance to establish a simple, portable, and in situ electrochemical sensor for ATZ. In the present work, a self-powered aptasensor (SPA) based on a novel enzyme-free photofuel cell (PFC) is successfully developed for ATZ for the first time. The designed SPA is constructed by the Ti-Fe-O nanotubes/nickel hydroxide (Ti-Fe-O NTs/Ni(OH)
