One-dimensional (1D) Zn₂GeO₄ rods were in-situ grown on Ni foam (NF) using a ethylenediamine (En)/water mixed solvent by a hydrothermal route in one single step. Such rhombohedral phase Zn₂GeO₄ rods are 1-2 μm in diameter and a few micrometers in length. Ethylenediamine is found to play a critical role in coordinating with starting zinc and germanium ions and acting as template. The Zn₂GeO₄/NF was developed as a new none-enzymatic hydrogen peroxide (H₂O₂) sensor. In electrochemical studies, the Zn₂GeO₄/NF electrode exhibits high sensitivity (3974 μM M m⁻¹ cm⁻²), wide linear detection range (1-4000μM), fast response (< 9 s), low detection limit (1 μM), excellent selectivity and stability towards H₂O₂. Several factors such as intrinsic nature of Zn₂GeO₄, the unique microstructure and the seamless contact with NF are believed to attributed to the excellent electrochemical sensing performances.
