The search for the ways of thermal stabilization of supported metal catalysts is an important challenge in the modern catalysis. Chemical modification of support seems to be the most versatile approach to stabilize the metal particles against sintering and alter their catalytic performance. Also for such modification nitrogen doping can be used and is considered rather perspective. In a recent manuscript (A.M. Dmitrachkov, R.I. Kvon, A.V. Nartova, N-doping of alumina thin film support to improve the thermal stability of catalysts: preparation and investigation, Appl. Surf. Sci.) we have developed the procedure of N-doping of alumina thin film grown at the surface of metal substrate. Proposed N-doped model alumina support is suitable for catalysis - oriented surface science studies and improves the resistance of supported metal particles against thermal driven sintering. Herein, we provide useful complementary data for the characterization of the prepared materials in the form of: in situ / ex situ XPS (X-ray photoelectron spectroscopy) spectra at every stage of sample preparation, including angle resolved XPS experiments and thermal stability tests; STM (scanning tunneling microscopy) images of supported gold catalysts. Presented data support the proposed mechanism of film formation and modification.
寻找负载型金属催化剂的热稳定化方法是现代催化领域的一项重要挑战。载体的化学改性似乎是稳定金属颗粒防止烧结并改变其催化性能的最通用方法。对于这种改性，也可以使用氮掺杂，并且被认为是相当有前景的。在最近的一篇论文（A.M. 德米特拉奇科夫、R.I. 克冯、A.V. 纳尔托娃，《用于提高催化剂热稳定性的氧化铝薄膜载体的氮掺杂：制备与研究》，《应用表面科学》）中，我们开发了在金属衬底表面生长的氧化铝薄膜的氮掺杂程序。所提出的氮掺杂模型氧化铝载体适用于面向催化的表面科学研究，并提高了负载型金属颗粒对热驱动烧结的抗性。在此，我们以以下形式提供了用于表征所制备材料的有用补充数据：在样品制备的每个阶段的原位/非原位X射线光电子能谱（XPS）光谱，包括角分辨XPS实验和热稳定性测试；负载型金催化剂的扫描隧道显微镜（STM）图像。所呈现的数据支持了所提出的成膜和改性机制。
