  • hexahedron prism anchored Octahedronal ceo2 crystal facet based homojunction promoting efficient solar fuel synthesis
    Journal of the American Chemical Society, 2015
    Co-Authors: Ping Li, Yong Zhou, Zong-yan Zhao, Xiaoyong Wang, Min Xiao, Qinfeng Xu, Zhigang Zou
    Abstract:

    An unprecedented, crystal facet-based CeO2 homojunction consisting of hexahedron prism-anchored Octahedron with exposed prism surface of {100} facets and Octahedron surface of {111} facets was fabricated through solution-based crystallographic-oriented epitaxial growth. The photocatalysis experiment reveals that growth of the prism arm on Octahedron allows to activate inert CeO2 Octahedron for an increase in phototocatalytic reduction of CO2 into methane. The pronounced photocatalytic performance is attributed to a synergistic effect of the following three factors: (1) band alignment of the {100} and {111} drives electrons and holes to Octahedron and prism surfaces, respectively, aiming to reach the most stable energy configuration and leading to a spatial charge separation for long duration; (2) crystallographic-oriented epitaxial growth of the CeO2 hexahedron prism arm on the Octahedron verified by the interfacial lattice fringe provides convenient and fast channels for the photogenerated carrier transp...

The proposed facet-based homojunction in this work may provide a new concept for the efficient separation and fast transfer of photoinduced charge carriers and enhancement of the photocatalytic performance.

  • hexagonal nanoplate textured micro Octahedron zn2sno4 combined effects toward enhanced efficiencies of dye sensitized solar cell and photoreduction of co2 into hydrocarbon fuels
    Crystal Growth & Design, 2012
    Co-Authors: Yong Zhou, Jiyuan Zhang, Qi Liu, Zhigang Zou
    Abstract:

    A complex, hexagonal nanoplate-textured micro-Octahedron Zn2SnO4, abbreviated as nanoplate/micro-Octahedrons, was synthesized with the assistance of l-tryptophan. The generation of this unique architecture was found to undergo two consecutive nucleation processes. In comparison with as-prepared micro-Octahedron and atactic particles, the complex architecture proves favorable for enhancement of overall dye-sensitized solar cells light-conversion efficiency via (1) generation of light scattering centers to be in favor of enhancing the light absorption; (2) enhancement of electron transport along the nanoplate; (3) facilitation of electrolyte diffusion as a result of the relatively open structure of the micro-Octahedron films. The unique nanoplate/micro-Octahedron Zn2SnO4 was also demonstrated to greatly promote the photocatalytic reduction of greenhouse gas (carbon dioxide, CO2) into renewable hydrocarbon fuel (methane, CH4) in the presence of water vapor.
