Ultrathin-nanosheet-based 3D hierarchical porous In2S3 microspheres: chemical transformation synthesis, characterization, and enhanced photocatalytic and photoelectrochemical property

Engineering two-dimensional (2D) ultrathin nanosheets into a hierarchical porous structure is one of the important challenges in material chemistry. We report a chemical transformation route to inorganic hierarchical In2S3 with a 3Dmicrosphere-like porous structure stacked by 2D ultrathin nanosheets via an organic-component depletion method of inorganic-organic hybrids as precursors. The as-prepared In2S3 has enhanced photocatalytic property for the degradation of methyl orange as well as a stable photoelectrochemical property.
