title: Leaf-like hybrid of bismuth subcarbonate nanotubes/graphene sheet with highly efficient photocatalytic activities.
abstract: In this work, leaf-like hybrid with Bi2O2CO3nanotubes as the "veins" and graphene sheet as the "laminae" is fabricated via a facile one-pot reaction of bismuth nitrate and graphene oxide in alkaline aqueous solution. With the uniform distribution of Bi2O2CO3nanotubes on the graphene substrate, the obtained Bi2O2CO3-NT/G manifests high specific surface area (90.4m2g-1) and large pore volume (0.197cm3g-1), which are favorable for the efficient light capturing together with the rapid transfer of mass and charge carriers. In comparison with the pure Bi2O2CO3nanotubes and commercial Bi2O2CO3, Bi2O2CO3-NT/G exhibits much enhanced activity and long-term stability towards the photocatalytic degradation of organic dye pollutant, which is owing to its unique leaf-like structural features.
