And the article contained the following:
BiFeO3 (BFO) nanocage prepared by metal-organic-framework derivatization (MOF-d) was adopted as activator to first investigate the effect mechanism of visible-light on naproxen-degradation via peroxymonosulfate (PMS) activation. MOF-d BFO expressed more excellent PMS activation ability than hydrothermal-synthetic BFO, due to highly ordered mesopores. A 3.0 times higher pseudo-first-order degradation rate constant was achieved after visible-light introduced. The quenching experiments indicated that the contribution of ROS in naproxen degradation followed the order of SO鈥?4>1O2 鈮?鈥H in MOF-d BFO/PMS/dark system, while changed into h+>1O2 > >O鈥?app2SO鈥?4> 鈥H after visible-light introduced. EPR tests first revealed that visible-light promoted 1O2 yield (non-radical pathway) but suppressed 鈥H and SO鈥?4 generation (free-radical pathways). N2-purging experiments further proved that 1O2 primarily originates from the reaction between h+ and PMS, equivalently to that between O2 and e–h+ in MOF-d BFO/PMS/vis system. Under visible-light, PMS activation via 顚咶e (III) might be hindered by e- filling on Fe 3d orbital and anion PMS preferred to approach h+ rather than e-, resulting in the decrease of 鈥H and SO鈥?4 yields. Moreover, PMS faces competition from adsorbed-O2 and oxygen-vacancies for e- capture. The degradation-pathways for naproxen in dark and under visible light were both proposed in MOF-d BFO/PMS system. The experimental process involved the reaction of 2-Methoxynaphthalene(cas: 93-04-9).Application of 93-04-9
