High-throughput production of highly efficient photocatalysts for hydrogen evolution remains a considerable challenge for materials scientists. Here, we produced extremely uniform high-quality graphene and molybdenum disulfide (MoS2) nanoplatelets through the electrochemical-assisted liquid-phase exfoliation, out of which we subsequently fabricated MoS2/graphene van der Waals heterostructures. Ultimately, zinc oxide (ZnO) nanoparticles were deposited into these two-dimensional heterostructures to produce an artificial ZnO/MoS2/graphene nanocomposite. This new composite experimentally exhibited an excellent photocatalytic efficiency in hydrogen evolution under the sunlight illumination ( λ > 400   n m ), owing to the extremely high electron mobilities in graphene nanoplatelets and the significant visible-light absorptions of MoS2. Moreover, due to the synergistic effects in MoS2 and graphene, the lifetime of excited carriers increased dramatically, which considerably improved the photocatalytic efficiency of the ZnO/MoS2/graphene heterostructure. We conclude that the novel artificial heterostructure presented here shows great potential for the high-efficient photocatalytic hydrogen generation and the high throughput production of visible-light photocatalysts for industrial applications.

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.

Fe Substitution

Perovskite SrTiO3 and Fe Substituted SrTiO3 were prepared by solid-state reaction route as visible light active photosensitive materials for solar-hydrogen generation applications. Powder X-ray diffraction pattern confirms the formation of crystalline perovskite SrTiO3 phase at sintering temperature of 1273 K. The pattern of Fe substituted SrTiO3 exhibits number of peaks with splits and less crystalline indicating a lower symmetry structure upon substation at Sr and Ti sites. Crystallinity and crystallite size also finds decrease with increased Fe substitution. The band gap of SrTiO3 obtained by DR UV-Vis absorbance analysis at various sintering temperature approaches the theoretical value 3.06 eV. However, on Fe substitution the band gap is reduced to ~ 2.0-2.5 eV suggesting the materials can extend its absorption to the visible range also. FT-IR spectra confirmed that the Fe substituted SrTiO3 is similar to that of pure phase with bands corresponding to the hydroxyl and carboxyl groups. Since the substituted materials show reduced band gap, these materials can be utilized for photosensitive solar-hydrogen generation.
