摘要

•Superficial potential trap is formed near Co atom in g-C3N4(Co).•Co atom act as a bridge to connect g-C3N4 and Pt NPs.•The bridging effect of Co atom can rapidly transfer the photo-induced electrons.•The water molecule is more easily dissociated by Co atom bridge.•The photocatalytic activity of g-C3N4(Co)-Pt is 145.8 times that of pristine g-C3N4.
