Facile fabrication of rod‐shaped Zn2GeO4 nanocrystals as photocatalyst for hydrogen production

Abstract

Nanorod‐shaped Zn2GeO4, an efficient photocatalytic hydrogen‐evolving catalyst, have been facilely prepared in high yield by a simple hydrothermal synthesis route. Based on the experimental results, an interesting synthetic strategy is realized and that the prismatic Zn2GeO4 nanorods prepared in a stoichiometric ratio exhibited much higher H2‐producing activity than the Zn2GeO4 nanorods prepared in the excess germanium, which possibly provided a clue for exploring the surface structure relationships of Zn2GeO4 single crystals and their intrinsic chemical properties.
