在环境危害中,特别是在没有自然光照射的情况下,有机污染物的严重泄漏情况下,光催化剂的吸附和光降解性能至关重要。采用表面配体辅助定域结晶法(SLALC)在350℃的低温条件下合成了立方相NaNbO_3(c-NaNbO_3)光催化剂,所合成的c-NaNbO_3纳米粒子在3h内可吸附95%的亚甲基蓝(MB),180min可光降解99.3%的MB。此外,所制备的c-NaNbO_3纳米粒子具有优异的吸附和光降解回收性能,在实际环境保护中显示出很大的潜力。
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 NaNbO3(c-NaNbO3) photocatalyst at a low temperature as 350 °C. The as synthesized c-NaNbO3nanoparticles could adsorb 95% of methylene blue (MB) in 3 min and photodegrade 99.3% of MB in 180 min. Moreover, the as prepared c-NaNbO3nanoparticles exhibit both outstanding adsorption and photodegradation recoverability, which shows great potential in actual environmental conservation.
