ZnFe2O4/ZnO nanoheterostructures are synthesized by a facile template method. The hydrogen generation rate of ZnFe2O4/ZnO nanoheterostructures without co-catalysts is up to 2.15 mmol h−1 g−1 under visible light irradiation (λ > 420 nm), which is 45 times higher than the best yields ever reported for ZnFe2O4-based photocatalysts.
