Hierarchical Brookite TiO2–Bi2MoO6 Nanospheres with Efficient Visible-Light-Driven Photocatalytic Response

Hierarchical TiO2–Bi2MoO6 nanospheres as efficient visible-light responsive photocatalyst are fabricated by dispersing brookite TiO2 nanorods on the hierarchical Bi2MoO6 nanospheres, which provides visible-light absorption and large surface area. The morphologies, surface area and light absorption features of as-prepared TiO2–Bi2MoO6 can be rational controlled by varying the loading amount of TiO2 nanorods on hierarchical Bi2MoO6 nanospheres. As a result, the TiO2–Bi2MoO6-3 yields 380 ppm CO2 production for decomposing 2-propanol at 11 h under visible light irradiation, realizing 4.4 times enhancement of photocatalytic property with respect to pure TiO2 nanorods. Moreover, the three-dimensional hierarchical architecture enables the hybrid TiO2–Bi2MoO6 excellent cycling stability.
