Pb—WC复合电极的电催化机理的研究

A Study of the Mechanism of Electrocatalysis of Pb-WC Composite Electrode

本文对 H_2在 Pb-WC 复合电催化电极上的析出机理建立了数学模型,验证了反应机理。用一种新的定量的计算法研究了反应控制步骤的活化能,得出 Pb 复合 WC 后使得氢析出催化活性提高的主要原因是反应控制步骤活化能降低了的结论。

In this thesis,a mathematical model was established for the mechanism of reduction of hydrogen ion on Pb-WC composite electrode.This mechanism is Verified by the model.It is found from the study of the activation energy of rate determing step using a new calculation method that the increase in catalytic activ- ity for hydrogen evolution of electrode after compositing WC particle into Pb is due to the decrease in activation energy of the rate determining step.
