摘要

周转率测量和表面科学技术的结合使得金属非均相催化速率的定量成为可能。有很多不同实验室的反应周转率相同的例子。然而，仍然存在一些问题，例如在贵金属上的碳氢化合物异构化和氢解过程中，来自不同实验室的周转率相差许多数量级。对这种差异的解释进行了讨论。在多相催化实验工作的指导方针，将有助于减少这种广泛分散的周转率在未来提出。*目前地址:伍斯特理工学院化学工程系，马萨诸塞州伍斯特01609-2280。

Reproducibility of Turnover Rates in Heterogeneous Metal Catalysis: Compilation of Data and Guidelines for Data Analysis

Abstract The combination of turnover rate measurements and surface science techniques allows a firm quantification of rates in heterogeneous catalysis by metals. There are many examples of reactions where the turnover rates from different laboratories are the same. However, there are still problems, as in the isomerization and hydrogenolysis of hydrocarbons over noble metals, where the turnovers rates from different laboratories differ by many orders of magnitude. An explanation for this discrepancy is discussed. Guidelines for experimental work in heterogeneous catalysis that will help to minimize this wide scatter of turnover rates in the future are presented. ∗Current address: Department of Chemical Engineering, Worcester Polytechnic Institute, Worcerster, MA 01609-2280.
