Facile in-situ synthesis of α-NiS/CdS p-n junction with enhanced photocatalytic H2 production activity
TL;DR: In this paper , a p-type semiconductor α-NiS is in-situ grown on an n type semiconductor CdS by a simple solid state method, which results in a strong interfacial contact between α−NiS and C−S. The strong interface contact is beneficial to the charge migration and promotes the charge separation efficiency.
