摘要：Based on energy band matching between RuO2and TiO2, the RuO2/TiO2nanobelt heterostructures are designed and fabricated. The formed heterostructures can efficiently enhance the separation of photogenerated electron-hole pairs and accelerate the transport of charges. Thanks to above-mentioned advantages, the RuO2/TiO2nanobelt heterostructures exhibit an improved photocatalytic performance compared with P25, TiO2, and RuO2under UV and visible light irradiation. Moreover, the nanopapers based on RuO2/TiO2nanobelt heterostructures have been prepared via a modified paper-making process. The paper-like porous RuO2/TiO2nanobelt heterostructures are applied in heterogeneous catalysis and present enhanced activity and selectivity for catalyzing aerobic oxidation of benzyl acohol. These results may provide a paradigm to fabricate and design the one-dimensional TiO2nanostructured surface heterostructures with high efficiency and performance.
