The self-assembly of two-dimensional(2D)semiconductor nanosheets into three-dimensional(3D)or-dered superstructures represents an ingenious way to avoid aggregation,expose massive available active sites and benefit the mass transfer,which maximizes the advantages of the 2D nanostructures in photo-catalysis.Herein,a flower-like superstructure of ternary semiconducting boron carbon nitride nanosheets(FS-BCNNSs)was synthesized through the morphology-preserved thermal transformation of a flower-like superstructure of boron-containing metal-organic framework nanosheets(FS-MOFNSs).Taking advantage of this functional superstructure,FS-BCNNSs was employed for the pioneering application in the field of photocatalytic hydrogen peroxide(H202)production and exhibited excellent photocatalytic performance,yielding an impressive rate of 1415.9 μmol g-1 h-1 for the production of H202.The results of this work offer not just a promising catalyst for photocatalytic H202 production but also a facile strategy to fabri-cate unique superstructures constructed from 2D nanosheets for catalysis,energy conversion,and other related fields.
