项目摘要

The present research aims at constructing model industrial catalyst systems suitable for STM examinations, thereby advancing STM applications to the examinations of practical industrial catalyst research.As most common industrial catalysts, supported metal catalysts were chosen. Silica and alumina were chosen as support materials, and Pt as metal catalyst component. Model supported metal catalysts composed of these constituents, and their STM images were obtained.STM examinations of nonconductive materials such as silica and alumina were made possible by making them as very thin films. Tunneling mechanism of such thin nonconductive films were also examined. As preparation techniques for the model supported catalysts vacuum deposition was found most varsatile.With the developments of these methodologies, it became possible to obtain information on atom arrangements and local electronic structures of catalyst surfaces that have not been possible with other existing methods. This gives rise to the expectations that heterogeneous catalyst reactions which are highly localized in nature may be examined and understood at atomic level.
本研究旨在构建适合STM检验的模型工业催化剂体系,从而将STM应用推进到实际工业催化剂研究的检验中。作为最常见的工业催化剂,选择了负载型金属催化剂。选择二氧化硅和氧化铝作为载体材料,并选择Pt作为金属催化剂组分。由这些成分组成的模型负载金属催化剂,并获得了它们的 STM 图像。通过将二氧化硅和氧化铝等非导电材料制成非常薄的薄膜,可以对它们进行 STM 检查。还研究了这种非导电薄膜的隧道机制。由于模型负载催化剂真空沉积的制备技术最为多变。随着这些方法的发展,获得有关催化剂表面的原子排列和局域电子结构的信息成为可能,这是其他现有方法无法实现的。这引起了人们的期望,即可以在原子水平上检查和理解本质上高度局域化的非均相催化剂反应。
