概要（目的・用途・実施内容）/ Abstract (Aim, Use Applications and Contents)
We synthesized ionic functionalized porous organic polymer (I-POP)-supported SnS2 composite photocatalysts, namely, SnS2-C@POP, for solar driven photocatalytic reaction. SnS2-C@POP is characterized by HRTEM and HAADF-STEM analysis in which SnS2 is exists as sheet type morphology well dispersed over the microporous polymer framework composed of a number of nanosheets having uniform sheet dimension.
実験 / Experimental
The morphology and dispersion of metal in polymer was analyzed by JEOL ARM-200 HAADF-STEM at 300 eV.
結果と考察 / Results and Discussion
The morphology of as-prepared SnS2-C@POP samples was characterized by High-resolution transmission electron microscopy (HRTEM) and High-angle annular dark-field scanning transmission electron microscopy (HAADF-STEM). SnS2-C@POP sample exhibit sheet type morphology well dispersed over the microporous polymer framework composed of a number of nanosheets having uniform sheet dimension ~ 200-350 nm; however, these aggregated nanosheets have rough surface (Figure 1a-c). Typical thickness of the SnS2-C@POP nanosheets is ~ 30-40 nm. The corresponding HAADF elemental mapping analysis of SnS2-C@POP catalyst in Figure 1e-h signifies that Sn (green), S (pink) and C (brown) are evenly distributed within the framework.
