文章要点1:在本文中,作者成功合成出一种多孔的薄层状Fe, Co, O共掺杂g−C3N4(FCOCN)催化剂,并将其作为过硫酸盐(PS)活化剂用于四环素(TC)的降解。研究发现Fe、Co和O掺杂可以增加比表面积与调控电子结构。在添加PS后,FCOCN2在120 min反应后表现出高达90.1%的TC去除效率,动力学常数是纯g−C3N4的2.67倍。
有鉴于此,黑龙江大学井立强、边辑、张紫晴等开发了一种掺杂B的g-C3N4(BCN),修饰配位不饱和FeOOH和CoOx簇,在没有加入牺牲剂的情况下从水和氧气中进行光催化合成H2O2。 本文要点 要点1.与g-C3N4相比,这种制备的催化剂在可见光下的活...
