Scale synthesized cubic NaNbO3 nanoparticles with recoverable adsorption and photodegradation for prompt removal of methylene blue

The adsorption and photodegradation performance are of paramount importance to photocatalysts in environmental hazards, especially in serious organic pollutants leaking emergency in the absence of natural light illumination. Here we demonstrated a surface ligand assisted localized crystallization (SLALC) method to scale synthesis of cubic phase NaNbO 3 (c-NaNbO 3 ) photocatalyst at a low temperature as 350 °C. The as synthesized c-NaNbO 3 nanoparticles could adsorb 95% of methylene blue (MB) in 3 min and photodegrade 99.3% of MB in 180 min. Moreover, the as prepared c-NaNbO 3 nanoparticles exhibit both outstanding adsorption and photodegradation recoverability, which shows great potential in actual environmental conservation.
