Abstract Ru-Fe bimetallic alloy nanoparticle catalyst (Ru-Fe/GO) was prepared by chemical reduction method on graphene oxide prepared using Hummers modified method. The structure and morphology of both GO and Ru-Fe/GO were analyzed using X-ray diffraction (XRD), Transmission electron microscopy (TEM) and energy dispersive spectroscopy (EDS, Fourier transform infrared spectroscopy (FTIR) and X-ray photoelectron spectroscopy (XPS).The effect of catalyst components on hydrogen generation rate for NaBH4 methanolysis was investigated. When Ru:Fe is 6:1, the catalytic activity is the highest, and the average rate is about 473 mL·min−1·g−1. The effect of temperature, Sodium hydroxide concentration, and sodium borohydride concentration on reaction rate is also discussed, and the activation energy for the methanolysis of sodium borohydride is 59.33 kJ·mol−1 based on the data.

硼氢化钠醇解制氢Ru-Fe/GO催化剂的制备及性能研究

摘要 采用 Hummers 改性法制备氧化石墨烯，采用化学还原法制备 Ru-Fe 双金属合金纳米粒子催化剂（Ru-Fe/GO）。使用 X 射线衍射 (XRD)、透射电子显微镜 (TEM) 和能量色散光谱 (EDS、傅里叶变换红外光谱 (FTIR) 和 X 射线光电子能谱) 分析了 GO 和 Ru-Fe/GO 的结构和形貌(XPS)。考察了催化剂组分对NaBH4甲醇分解产氢速率的影响，当Ru:Fe为6:1时，催化活性最高，平均速率约为473 mL·min-1·g- 1. 还讨论了温度、氢氧化钠浓度和硼氢化钠浓度对反应速率的影响，硼氢化钠甲醇分解的活化能为59。
