水素製造反応触媒用のナノポーラスモリブデンコバルト金属間化合物の開発を完了しました。得られたナノポーラス構造の組成が均一であるように見える一連のNi-Co-Mo前駆体合金の製造が完了しました。 LMDプロセス中に温度と時間を調整することにより、ターゲットのナノ構造と組成が得られます。 9つのナノポーラスMo-Coの相組成に対して、d-金属触媒の特別な理論的再調整を実行する必要があります。最適化されたナノ構造と組成が完成し、ナノポーラスモリブデンコバルトの触媒性能が評価されました。上記の触媒の触媒活性と安定性の評価は完了しました。 Mo-Coシステムで得られたメカニズムは、Mo-FeシステムとMo-Crシステムにまで及びます。材料の調製条件を最適化することにより、より小さなサイズのMo-Co多孔質構造が得られ、その電極触媒性能が最適化されました。対称性と軌道の重なりの相組成が異なるため、異なる触媒活性が得られます。上記の材料を調製するための液体金属脱合金の熱力学および動力学を研究した。学術雑誌(Song, Ruirui, Jiuhui Han, Masayuki Okugawa, Rodion Belosludov, Takeshi Wada, Jing Jiang, Daixiu Wei et al.

The water-based reaction catalyst has been successfully used in the production of water-based reaction catalysts through the use of intermetallic compounds. The results show that the composition of the Ni-Co-Mo precursor alloy has been completed. In the middle of the LMD system, the temperature and temperature of the system is adjusted to make sure that the components of the system are in good condition. 9. It is necessary to make sure that the phase composition of Mo-Co and d-metal catalyst can be adjusted according to the special theory. The most effective way to improve the performance of the catalyst is to complete the system. The last "catalyst" catalyst activity, "stability", "stability" is over. Mo-Co won't get any trouble, Mo-Fe won't get any trouble, and Mo-Fe won't have any trouble with Mo-Cr. The optimization of material conditions, the production of porous Mo-Co, the performance of cathode catalyst and the performance of cathode catalyst. The weight of the phase is divided into two groups, the catalytic activity of the catalyst is high. Materials, liquid Metal Dealloying, Mechanics, Kinetics Research.
