Hexagonal-phase WO3 nanosheet with dominant facets was synthesized by a solvothermal-calcination method, and CuO was composite and the electrodeposition method. The Cu O/WO-001 composite nanosheets exhibited an excellent photocatalytic CO reduction performance under visible irradiation(λ > 400 nm). The yields of CO, O and H using Cu O/WO-001 photocatalysts reached 11.7, 5.7 and 0.7 μmol, respectively, after24 h visible-light illumination and the photocatalyst showed good photocatalytic activity in the fourth cycling *** enhanced photocatalytic activity was ascribed to the efficient separation of the photoinduced charges derived from the constructed heterojunction in the nanosheet composite. The(0 0 1) facet of hexagonal phase WO was in favor of the transfer between the photo-induced holes and the water molecules, conducing to H O oxidation in the CO reduction process. The indirect Z-scheme charge transfer mode of Cu O/WO was then demonstrated by measuring band structures and the potential mechanism of CO reduction is further proposed. The present research is expected to be useful in developing Z-scheme photocatalysts of WO-based nanosheet, and provides meaningful information for hopefully stimulating more insightful investigations of systematical design and controlled assembly of visible-light-driven photocatalysts.

The conversion of anthropogenic CO2 into chemical feedstocks can supplement the natural carbon cycle and might reduce global energy and environment burdens. The semiconductor photocatalyts, such as TiO2,[1] WO[2]3-x and BiV O4,[3] play an important role in reduction of CO2 back to value-added chemicals by solar energy. To overcome the serious drawbacks of rapid charge recombination and the limited visible-light absorption of such semiconductors,[4] the Z-scheme heterostructure photocatalysts, which directly quenches the weaker oxidative holes and reductive electrons in the solid heterostructure interfaces, has proved to be a more preferable one for CO2 photoreduction.[5] Herein, we synthesized Z-scheme photocatalyst Fe2O3/Cu2O by a solvothermal and precipitation route, which was characterized using XRD, XPS, TEM, DRS, UPS. Photocatalytic activities of the as-prepared Fe2O3/Cu2O photocatalysts were evaluated by the photocatalytic reduction of CO2 in water vapor under visible irradiation. The results indicated that the Z-scheme Fe2O3/Cu2O photocatalysts have great selectivity, high photocatalytic performance and excellent reusability.

Increasing the efficiency of dye degradation is a critical issue for the application for photocatalysis. It is one of the greatest challenges to enhance the utilization of photogenerated carriers in semiconductor, especially for sunlight irradiation.[1] In this study, I/C-codoped TiO2 was synthesized by a simple solvothermal-calcination method. The codoping interstitial carbon and substitutional iodine not only widened the light absorption range of the TiO2 photocatalysts, but also enhanced the separation of photo-induced carriers.

Graphitic carbon nitride（g-C3N4） has recently been received much attention in the field of photocatalysis such as hydrogen evolution [1], CO2 reduction [2] and photodegradation of organic pollutants [3] due to its nontoxic, high-efficiency and chemical stability. As to the photodegradation of organic dyes in aqueous system, g-C3N4 exhibits higher visible light photocatalytic activity in comparison with that of conventional photocatalyst like C-doped TiO 2 [4]. During the photodegradation process of organic dyes, the solution p H is an important factor [5, 6] since the proton concentration in the solution exacts great influence not only on the surface charge but on the structure of the dye and the active species as well. Herein, g-C3N4 with high surface area was synthesized via calcining urea and characterized by XRD, IR, BET, DRS and XPS. The photocatalytic degradation performance of g-C3N4 towards Rhodamine B（RhB） was investigated and the influence of pH values on the photodegradation of RhB was studied systemically. Results show that the p H values influence significantly the photodegradation rate and efficiency of Rh B. The optimal p H value is determined to be 4.3, at which RhB were decomposed completely within 15 minutes. The adsorption and decolorization kinetics of Rh B on g-C3N4 were further studied according to Langmuir-Hinshelwood（L-H） model and the photodegradation mechanism was investigated by electron spin resonance（ESR）. It suggests that the hydroxyl radical is the main active species in the photocatalytic oxidation process.
