| 英文摘要 | Safe and efficient hydrogen storage remains a grand challenge in the widespread implementation of hydrogen fuel cell technology. Recently, chemical hydrogen storage has emerged as a promising alternative for vehicular and portable applications. A number of hydrogen-rich materials have been experimentally demonstrated to deliver large amounts of hydrogen under mild conditions with controllable kinetics. Among these materials of interest, hydrous hydrazine (N2H4 center dot H2O) is a promising but yet not fully explored candidate. The development of highly efficient catalyst and its reaction kinetics law are the key issues of N2H4 center dot H2O-based hydrogen generation (HG) systems. Herein, a supported Ni-Pt/La2O3 catalyst was prepared by a combination of co-precipitation and galvanic replacement methods. Via optimizing preparing processes, the developed catalyst enabled a complete decomposition of N2H4 center dot H2O to generate H-2 at a reaction rate of 340 h(-1) at 323 K, which outperforms most reported N2H4 center dot H2O decomposition catalysts. Phase/structural analyses by XRD, TEM and XPS were carried out to gain insight into the catalytic performance of the Ni-Pt/La2O3 catalyst. In addition, the effects of temperature, concentration of N2H4 center dot H2O and NaOH, and amount of catalyst on the N2H4 center dot H2O decomposition were investigated over the Ni-Pt/La2O3 catalyst. The kinetic rate equation may be represented by the expression: r = -d[N2H4 center dot H2O]/dt = 2435exp(-51.53/(RT)) [N2H4 center dot H2O](0) (3)[NaOH](0(0 12))[Ni](1 03). The obtained results should lay the experimental and theoretical foundation for developing practical application of N2H4 center dot H2O-based HG system. |
