  1. Synthesis of ZnIn2S4 nanosheet for reduction of CO2 in methanol Reporter: Jingshuai Chen Supervisor: Prof. Xin 2013. 10. 22

  2. Introduction Nanoporous Single-Crystal-Like CdxZn1-xS Nanosheets Fabricated by the Cation-Exchange Reaction of Inorganic–Organic Hybrid ZnS–Amine with Cadmium Ions Yifu Yu, et.al., Angew. Chem. Int. Ed. 2012, 51, 897 –900

  3. b) TEM images of the ZnS–DETA hybrid sheets. d–f) TEM and HRTEM images (d and its inset), SEM image, and EDX spectrum of the nanoporous Cd0.5Zn0.5S nanosheets.

  4. g–l) SEM (g, h), TEM (i), HRTEM images of single-crystal-like nanoporous CdS nanosheets obtained by the cation-exchange strategy of hybrid precursors. a) UV/Vis diffuse reflectance spectra and b) time course of evolved H2 under irradiation of visible light of the as-prepared Zn0.5Cd0.5S porous nanosheets and Zn0.5Cd0.5S nanorods.

  5. Synthesis of ultrathin CdS nanosheets as efficient visible-light-driven water splitting photocatalysts for hydrogen evolution You Xu, et al., Chem. Commun., 2013, 49, 9803--9805

  6. (a and b) SEM images of the inorganic–organic hybrid CdS–DETA nanosheets. (c and d) TEM images of ultrathin CdS nanosheets. The inset in (d) is the photograph of the colloidal CdS dispersion. The light beam is incident from the side to demonstrate the Tyndall effect. (a) Comparison of the activity of different photocatalysts: CdS nanoparticles (I), CdS–DETA nanosheets (II), CdS nanosheet-based aggregates (III) and ultrathin CdS nanosheet dispersion (IV). (b) Time course of photocatalytic H2 production over ultrathin CdS nanosheets

  7. XRD pattern hexagonal cubic ZnIn2S4 exhibits two distinct polymorphs based on cubic and hexagonal lattices. Generally, hexagonal ZnIn2S4 is thermodynamically stable, whereas the cubic polymorph is a high pressure phase.

  8. DETA&H2O as solvent Hydrothermalmethod a) ZnIn2S4-DETA, b) ZnIn2S4; c)microsphere, d)nanosheet ZnIn2S4.
