摘要Self-assembly of (BiO)2CO3 nanoflakes on graphene (Ge) and graphene oxide (GO) nanosheets, as an effective strategy to improve the photocatalytic performance of two-dimensional (2D) nanostructured materials, were realized by a one-pot efficient capture of atmospheric CO2 at room temperature. The as-synthesized samples were characterized by XRD, SEM, TEM, XPS, UV-vis DRS, Time-resolved ns-level PL and BET-BJH measurement. The photocatalytic activity of the obtained samples was evaluated by the removal of NO at the indoor air level under simulated solar-light irradiation. Compared with pure (BiO)2CO3, (BiO)2CO3/Ge and (BiO)2CO3/GO nanocomposites exhibited enhanced photocatalytic activity due to their large surface areas and pore volume, and efficient charge separation and transfer. The present work could provide a simple method to construct 2D nanocomposites by efficient utilization of CO2 in green synthetic strategy. © 2015 Elsevier B.V. All rights reserved.
