| Abstract |
The Manganese-Cobalt composites (A-MnCo) are synthesized by a hydrothermal method under an aqueous basic condition and annealing process at 500 oC under hydrogen condition. The physicochemical properties of prepared powders are characterized by X-ray powder diffraction, high-resolution transmission electron microscope and X-ray photoelectron spectrometer. The XRD patterns of Manganese-Cobalt composites without annealing process (MnCo) represented the spinel structure ((Co,Mn)(Co,Mn)2O4). After being annealed, we confirmed that metallic cobalt and MnO are formed from mainly the spinel structures of MnCo. A-MnCo exhibits the TOF value of 14 h-1 with 100 % selectivity for hydrogen generation form hydrazine monohydrate. However, MnCo does not act as catalyst for hydrazine decomposition. In addition, A-MnCo showed improved TOF value for the decomposition of hydrazine monohydrate compared with that of metallic Co (3 h-1), and MnO (0 h-1), respectively. |
