Application of pea-like yolk-shell structured FeO@TiO nanosheets for photocatalytic and photo-Fenton oxidation of bisphenol-A.

Uniform pea-like yolk-shell (PLYS) structured magnetic TiO(PLYS-FeO@TiO) nanosheets have been prepared a combined kinetics-controlled mechanical force-driven and hydrothermal etching assisted crystallization method and characterized. The resulting PLYS-FeO@TiO nanosheets possess well defined yolk-shell structures with a large BET surface area (∼187.26 m g) and a strong magnetic susceptibility (∼17.4 emu g). The reaction rate constant was 24.2 × 10 min as a result of oxidative decomposition of BPA using UV/PLYS-FeO@TiO/HO system. This is 1.1 and 8.34 times faster than the BPA decomposition reaction rate constant in UV/TiO/HO and UV/FeO/HO systems, respectively. The synthesized catalyst also exhibited excellent recycle capability and excellent acid decomposition performance.
