Design a composite photocatalyst for a photocatalytic reaction is a powerful way to improve the photocatalytic performance. Herein, we reported a three-component composite 2Au@1%-ZFO/CN for H2 evolution in the triethanolamine aqueous solution under visible-light. ZnFe2O4 and C3N4 prepared by solid-state method are the main components of the composite, which was prepared via a hydrothermal method. And then, the Au-nanoparticles were dispersed on it by a photodeposition method. The morphology of the sample is that particle ZnFe2O4 is wrapped by particle C3N4. The Au-nanoparticles with a size of ∼ 6 nm were dispersed over sample C3N4, which acts as an active site, hot electron provider, and electronic channel. The photocatalytic performances of H2 evolution for these composites were studied in detail. The H2 evolution rate of the optimal sample 2Au@1%-ZFO/CN is 1622.3 and 1846.4 μmol/h/g under ultraviolet-light, simulated sunlight irradiation, respectively, which are 10.7-folds and 128.2-folds higher than that of the unloaded sample. The unloaded sample has no detectable photocatalytic performance under visible light. However, the optimal sample has an H2 evolution rate of 36.6 μmol/h/g. Moreover, its apparent quantum yield is 47.6% at 400 nm. The construction of three-component composites is a promising strategy for the study of photocatalytic properties.
