摘要：Porous two-dimensional (2D) nanomaterials have attracted much attention in recent years and shown unique electronic and physicochemical properties by utilizing the advantages of both porous structure and 2D architecture. However, the low-cost, large-scale, and high-quality synthesis of porous 2D nanomaterials is still very challenging. Herein, for the first time, we develop a facile manual grinding strategy for the preparation of ultrathin porous sulfur (S8)-anchored ScOOH nanosheets (S8/ScOOH-NSs) by the mechanical stripping of S8-anchored ScOOH nanorods (S8/ScOOH-NRs). The formation of S8/ScOOH-NSs should be due to the intrinsic lamellar structure of S8/ScOOH-NRs. The obtained S8/ScOOH-NSs with rich mesopores have a high-quality crystal structure. Because of hydrophobic sulfur and carbon components on the surface, S8/ScOOH-NSs show good hydrophobicity. In addition, S8/ScOOH-NSs exhibit more excellent photo- thermal conversion efficiency and adsorption capacity compared with S8/ScOOH-NRs, which is directly attributed to the synergistic effect of sulfur-doping, porous structure, and 2D architecture. Therefore, the facile and large-scale synthesis strategy endows S8/ ScOOH-NSs with multifunctional properties that have application prospects in water and photothermal evaporators.
