Bi/BiOBrxI1−x heterojunction of hierarchical microspheres formed in situ with efficient visible-light photocatalytic activity were synthesized by a facile one-step solvothermal method.
In order to surmount the intrinsic disadvantages of raw g-C3N4, we demonstrate simple thermal oxidation exfoliation and facile in situ photoreduction methods to fabricate Au/g-C3N4 nanosheet/reduced graphene oxide (Au/CNNS/rGO) photocatalysts.
