Herein we report a room-temperature synthesis of chemically bonded TiO2 (P25)-graphene composite hydrogels and their use as high performance visible light photocatalysts. The three-dimensional (3D) TiO2-carbon composite exhibits a significant enhancement in the reaction rate in the decontamination of methylene blue, compared to the bare P25. The 3D P25-graphene hydrogel is much easier to prepare and apply as a macroscopic device, compared to the 2D P25-graphene sheets. This work could provide new insights into the room-temperature synthesis of graphene-based materials. As a kind of the novel 3D graphene-based composite, the obtained high performance P25-graphene gel could be widely used in the environmental protection issues.
在此，我们报告了一种室温下合成化学键合的 TiO2（P25）-石墨烯复合水凝胶的方法，并将其用作高性能可见光光催化剂。与纯 P25 相比，三维（3D）TiO2-碳复合材料在亚甲基蓝的净化反应中表现出显著的反应速率提高。与 2D P25-石墨烯片相比，3D P25-石墨烯水凝胶更容易制备和应用于宏观器件。这项工作为室温下合成基于石墨烯的材料提供了新的思路。作为一种新型的 3D 基于石墨烯的复合材料，所获得的高性能 P25-石墨烯凝胶可广泛应用于环境保护问题。
