摘要

Reactive facets of heterogeneous photocatalysts play an important role during the water photolysis process since they afford the active sites/planes for the photoredox splitting of water or loading of co-catalysts.Recent studies indicated that the facets also play additional roles during charge separation.Therefore, identifying and exploring howthe reactivefacetsfacilitate the reactivity is considered to be a crucial step for developing high-performance photocatalysts for solar to chemical energy conversion.Investigations of the reactive facets have mainly focused on inorganic photocatalysts.There are only few reports about the exact reactive facets of polymeric carbon nitride (PCN) due to its low crystallinity and instability under the irradiation of high-energy electron beams.The PTI (polytriazine imide) intercalated with LiCl (PTI/Li+Cl-), which is synthesized by ionothermal methods, forms an ideal system for exploring the reactive facets of conjugated polymers because of its high crystallinity.
