Abstract

The effect of metal promoters (Mo, Sn, and Cd) on the performance of the 10Ni/La.Al nanocrystalline catalyst in Glycerol Dry Reforming (GDR) was investigated. 2x.10Ni/La.Al (x = Mo, Sn, and Cd) catalysts were prepared using the solid-state method and 10 wt.% Ni and 2 wt.% Mo, Sn, and Cd were added to the catalyst using the impregnation method. The catalysts were characterized by BET, X-ray diffraction, temperature-programmed reduction (TPR), oxidation (TPO), Raman, and scanning electron microscopies (SEM) techniques. It was found that adding Mo caused an increase in glycerol conversion and improved the long-term stability of the 10Ni/La.Al. Furthermore, catalysts with different amounts of promoter loading (2, 4, and 6 wt%) were synthesized to evaluate the optimum amount of Mo. 4Mo.10Ni/La.Al was selected to achieve 58 % glycerol conversion and the best stability.

通过金属促进剂提高甘油干转化性能：添加钼、锡和镉的 10Ni/La.Al 催化剂研究

研究了金属促进剂（钼、锡和镉）对 10Ni/La.Al 纳米晶催化剂在甘油干转化（GDR）中性能的影响。采用固态法制备了 2x.10Ni/La.Al（x = Mo、Sn 和 Cd）催化剂，并采用浸渍法在催化剂中添加了 10 wt.% Ni 和 2 wt.% Mo、Sn 和 Cd。通过 BET、X 射线衍射、温度编程还原 (TPR)、氧化 (TPO)、拉曼和扫描电子显微镜 (SEM) 技术对催化剂进行了表征。研究发现，添加 Mo 可提高甘油转化率，并改善 10Ni/La.Al 的长期稳定性。此外，还合成了不同促进剂负载量（2、4 和 6 wt%）的催化剂，以评估 Mo 的最佳用量。结果表明，4Mo.10Ni/La.Al 的甘油转化率为 58%，稳定性最佳。

期刊介绍： Materials Research Bulletin is an international journal reporting high-impact research on processing-structure-property relationships in functional materials and nanomaterials with interesting electronic, magnetic, optical, thermal, mechanical or catalytic properties. Papers purely on thermodynamics or theoretical calculations (e.g., density functional theory) do not fall within the scope of the journal unless they also demonstrate a clear link to physical properties. Topics covered include functional materials (e.g., dielectrics, pyroelectrics, piezoelectrics, ferroelectrics, relaxors, thermoelectrics, etc.); electrochemistry and solid-state ionics (e.g., photovoltaics, batteries, sensors, and fuel cells); nanomaterials, graphene, and nanocomposites; luminescence and photocatalysis; crystal-structure and defect-structure analysis; novel electronics; non-crystalline solids; flexible electronics; protein-material interactions; and polymeric ion-exchange membranes.
