Ni/Co/Ti layered double hydroxide for highly efficient photocatalytic degradation of Rhodamine B and Acid Red G: a comparative study.

ABSTRACT: Optically responsive, luminescent Ni/Co/Ti layered double hydroxide (LDH), synthesized by a single step hydrothermal route, exhibits highly efficient photodegradation of cationic and anionic dyes, Rhodamine B (∼99.8%) and Acid Red G (∼99.6%) respectively, better than that of commercial catalysts like NiO, CoO and TiO₂. The LDH has been characterized by using XRD, XPS, PL, TRES, EIS, TEM, SEM-EDX, AFM, UV-visible DRS, N₂-sorption desorption, ξ-potential, FT-IR and TG techniques. The characterized results indicate that the LDH possesses hexagonal morphology, a high surface area, a narrow band gap, defect states and oxygen vacancies within its layered framework. The degradations follow the e^--h⁺ hopping pattern and dye-photosensitized mechanistic pa
