Data files for The Influence of Phase Purity on the Stability of Pt/LaAlO3 Catalysts in the Aqueous Phase Reforming of Glycerol

XRD, XPS, IR, and PDF data are included as accessible files for the fresh and recovered Pt/LaAlO3-c and LaAlO3-c (where c = calcination temperature of the support at 700, 900, 1100 °C). Characterisation of the fresh materials allowed for identification of amorphous lanthanum carbonate phases in the 700 °C calcined sample that was not present in the higher calcined materials. The recovered Pt/LaAlO3-c were characterised after the aqueous phase reforming (APR) of glycerol to understand effects of real catalytic reactions on material structure. Additionally, the recovered LaAlO3-c were characterised after simulated reactions with acidic reaction products (lactic acid and CO2) to deconvolute the effects of specific reaction products on material stability. It is essential to note that multiple advanced characterisation techniques were required to fully characterise any amorphous content and the early-stage decomposition that occurs during the reactions.

本数据集包含了新鲜及再生Pt/LaAlO3-c和LaAlO3-c（其中c代表载体的煅烧温度，分别为700°C、900°C、1100°C）的X射线衍射（XRD）、X射线光电子能谱（XPS）、红外光谱（IR）和拉曼光谱（PDF）数据。对新鲜材料的表征揭示了在700°C煅烧样品中存在的非晶态镧碳酸盐相，而在更高温度煅烧的材料中则未观察到。再生Pt/LaAlO3-c样品在甘油水相重构（APR）反应后进行了表征，以探究真实催化反应对材料结构的影响。此外，再生LaAlO3-c样品在与酸性反应产物（乳酸和二氧化碳）的模拟反应后也进行了表征，以解析特定反应产物对材料稳定性的影响。值得注意的是，为了全面表征任何非晶态含量以及反应过程中发生的早期分解，需要运用多种高级表征技术。
