Mannitol-assisted synthesis of ultrathin Bi 2 MoO 6 architectures: excellent selective adsorption and photocatalytic performance

Abstract

Ultrathin structures have gained more and more attention due to their large surface area and abundant reactive sites, which are beneficial for the improvement of performances. Herein, we report an ultrathin Bi₂MoO₆ synthesized by a simple mannitol-assisted hydrothermal method for the first time. The as-synthesized ultrathin Bi₂MoO₆ exhibits highly selective adsorption efficiency toward various positively charged organic dyes. Moreover, the ultrathin Bi₂MoO₆ displays enhanced photocatalytic activity in comparison with pristine Bi₂MoO₆. Systematic photoelectrochemical measurements reveal that the higher separation efficiency of photogenerated carriers takes responsibility for the improved photocatalytic performance. This work provides a simple path for designing ultrathin nanoarchitectures and widening application for these ultrathin materials.
