The synthesis of novel Co doped Zn2GeO4 hollow micro-spheres and the enhanced electrochemical performance for lithium-ion batteries.

Non-layered γ-Ga2O3 nanosheets were firstly prepared through a facile method and exhibited excellent photocatalytic activity of water splitting under UV light irradiation.

Crystal orientation-ordered hexagonal Zn 2 GeO 4 nanorod-bundles have been obtained via a synergistic self-assembly route. Each nanorod unit of the bundles maintains its individual hexagonal rod-shaped structure and is dominated by ( 110) and ( 1 10) facets, and all of them are aligned parallel to the growth direction in a high density. An ordered self-assembly of anisotropic nanorods was suggested to elucidate the formation of the unique bundle structures. The novel structure of Zn 2 GeO 4 bundles assembled from hexagonal nanorods leads to a surprisingly high UV-light-driven activity for the photocatalytic decomposition of water-methanol solution to hydrogen. The correlation of structure and photocatalytic activity of the ordered nanorod-bundles was discussed, indicating a new strategy of bundling Zn 2 GeO 4 nanorods with reactive facets to effectively enhance photocatalytic activities of 1-D nanostructures.
