Carrier Transfer

Introducing alkali halides during thermal condensation of melamine disturbs periodic ordering in the basal plane, reduces the band gap, and facilitates charge carrier transfer and separation, and thus enhances the photocatalytic performance of g-C3N4.

Charge-carrier transfer (CT) from the perovskite host to PbS QDs were studied using fs-transient absorption and THz techniques. The CT rate constants increase with the size of QDs due to a change in the position of valence and conduction bands in PbS QDs.

Two structures CdS–g-C3N4 and CdS@Au–g-C3N4 were observed in ternary composite CdS/Au/g-C3N4, and their photocatalytic mechanisms for RhB degradation over CdS/Au/g-C3N4 photocatalyst were proposed.
