Enwrapping graphdiyne (g-CnH2n−2) on hollow NiCo2O4 nanocages derived from a Prussian blue analogue as a p–n heterojunction for highly efficient photocatalytic hydrogen evolution

A new carbon material of graphdiyne (g-C n H 2 n −2 ) was prepared by reduction elimination reaction assisted by ball milling and the coupling of NiCo 2 O 4 and GDY to construct a p–n heterojunction for highly efficient photocatalytic hydrogen evolution.
