Uniform pea-like yolk-shell (PLYS) structured magnetic TiO2(PLYS-Fe3O4@TiO2) nanosheets have been prepared via a combined kinetics-controlled mechanical force-driven and hydrothermal etching assisted crystallization method and characterized. The resulting PLYS-Fe3O4@TiO2 nanosheets possess well defined yolk-shell structures with a large BET surface area (∼187.26 m2 g-1) and a strong magnetic susceptibility (∼17.4 emu g-1). The reaction rate constant was 24.2 × 10-2 min-1 as a result of oxidative decomposition of BPA using UV/PLYS-Fe3O4@TiO2/H2O2 system. This is 1.1 and 8.34 times faster than the BPA decomposition reaction rate constant in UV/TiO2/H2O2 and UV/Fe3O4/H2O2 systems, respectively. The synthesized catalyst also exhibited excellent recycle capability and excellent acid decomposition performance.
