In this work, leaf-like hybrid with Bi 2 O 2 CO 3 nanotubes 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 Bi 2 O 2 CO 3 nanotubes on the graphene substrate, the obtained Bi 2 O 2 CO 3 -NT/G manifests high specific surface area (90.4 m 2 g −1 ) and large pore volume (0.197 cm 3 g −1 ), which are favorable for the efficient light capturing together with the rapid transfer of mass and charge carriers. In comparison with the pure Bi 2 O 2 CO 3 nanotubes and commercial Bi 2 O 2 CO 3 , Bi 2 O 2 CO 3 -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.
