Industry/University Cooperative Research: The Measurement of Electrical Properties of Supported Metal Crystallites Using a Microwave Hall-Effect Technique

本研究计划将使用微波霍尔效应的新应用来探测非金属载体上非常小的金属颗粒的物理和化学。这类催化剂广泛应用于各种化学合成。这项研究的结果有望产生一种独特的方法来测量负载金属催化剂的电子性质，并对催化科学做出其他贡献，包括：也就是说原位;允许在一系列操作条件下测定数据的Ro方法；当两种或两种以上金属以小簇形式存在于非金属支撑物上时合金效应的数据；一种表征散装催化剂的新方法新的证据有助于理解强金属支撑相互作用的详细机制。

This research program will use a new application of the microwave Hall-effect to probe the physics and chemistry of very small metal particles on non-metallic supports. This catalyst class is of interest for a wide variety of chemical synthesis. The results of this investigation are expected to produce a unique method to measure electronic properties of supported metal catalysts, and to make other contributions to the science of catalysis including: an ;itin situ;ro method that allows data determination under a range of operating conditions; data on the alloy effects when two or more metals are present as small clusters on non-metallic supports; a new method to characterize bulk catalysts; and new evidence to help understand the detailed mechanisms of strong metal support interaction.
