It is still a challenge for photocatalytic reduction of uranyl and maintaining catalyst stability under aerobic conditions. Herein, a catalyst of sodium–potassium co-doped g-C3N4 (CD-NaK) was obtained to remove Hexavalent Uranium (U(VI)) by photocatalytic reduction under aerobic conditions. And the CD-NaK was characterized by XRD, XPS and other methods. Furthermore, DFT calculations and XRD revealed that Na was doped in-plane while K was doped in-plane and interlayer, enhancing holes and electrons separation performance. Moreover, the removal ...
