Facile and robust construction of a 3D-hierarchical NaNbO3-nanorod/ZnIn2S4 heterojunction towards ultra-high photocatalytic H2 production

The robust 3D-hierarchical NaNbO 3 -nanorod/ZnIn 2 S 4 heterojunction shows a striking H 2 -evolution rate of 30.04 mmol h −1 g −1 under sunlight, the highest among reported NaNbO 3 and ZnIn 2 S 4 -based photocatalysts to date.
