Constructing built-in electric field in graphitic carbon nitride hollow nanospheres by co-doping and modified in-situ Ni2P for broad spectrum photocatalytic activity

Engineering interface structures for heterojunction photocatalysts

“…A large number of experimental results show that for semiconductor photocatalysts, the close interface between a noble metal with the semiconductor is the key to achieving high-efficiency separation and transfer of photogenerated carriers. 139,140 Zhang et al 141 assembled W 18 O 49 nanowires onto Au embedded TiO 2 . The interfacial distance (<10 nm) between Au and the adjacent W 18 O 49 can induce strong proton coupling, resulting in an active “hot spot” in the substructure (Fig.…”
