摘    要:以葡聚糖为软模板制备了多孔AgRu合金催化剂,利用X射线衍射仪和扫描电镜仪对其结构和形貌进行表征,并研究了其催化性能。结果表明,6种催化剂的催化产氢活性次序为Ag9.2Ru>Ag3.6Ru>Ag4.0Ru>Ag13.5-Ru>Ag21.3Ru>Ag22.4Ru。银钌原子比和催化剂形貌共同影响催化剂性能。其中选用Ag9.2 Ru催化剂考察了NaBH4和NaOH的质量分数对产氢速率的影响,研究结果表明,随NaBH4和NaOH质量分数的增加,催化产氢速率降低。

关 键 词:银钌合金  硼氢化钠  催化水解

Abstract:Porous Ag-Ru alloy catalysts were synthesized with dextran as soft template.The characterizations of catalysts were studied by XRD and SEM,and the activity on hydrogen generation rate decreased in the following order Ag_(9.2)Ru>Ag_(3.6)Ru>Ag_(4.0)Ru>Ag_(13.5)Ru>Ag_(21.3)Ru>Ag_(22.4)Ru.The performance of the catalysts was influenced by the atom ratio of Ag to Ru and catalyst form.The influences of concentration of NaBH_4 and NaOH on hydrogen generation rate with Ag_(9.2)Ru catalyst were studied,indicating th...
Keywords:Ag-Ru alloys  sodium borohydride  catalytic hydrolysis
