在可见光照射下，Bi/BiOCl异质结结构中的激发电子转移到氧空位态，然后转移到Bi金属纳米颗粒上，导致电子-空穴对的有效分离。该异质结光催化剂在光降解RhB染料和持久性有机污染物方面表现出非常高的活性，即RhB在2分钟内被完全降解。
Under visible light irradiation, excited electrons in heterojunction structure of Bi/BiOCl were transferred into oxygen vacancies states, and then to the Bi metal nanoparticles, resulting in effective separation of electron-hole pairs. The heterojunction photocatalyst exhibited an extraordinary high activity in photodegradation of RhB dye and persistent organic pollutants, i.e. RhB was completely degraded in 2 minutes.
