多相催化和电催化在大气污染控制中有着非常有效的应用。来自移动的排放源或固定排放源的空气排放物，包括挥发性有机物排放物、氮氧化物、碳氢化合物和一氧化碳，可以在合理的温度下，通过利用多相催化和适当催化剂的具有成本效益的系统，很好地转化为无害的非污染物。传统的多相催化剂的一些缺点是生产成本高（因为它们中的大多数是金属负载的催化剂）、寿命短（由于催化剂失活）和在催化过程中控制它们的活性的弱点。一种新的固态电化学现象，称为电化学促进催化（EPOC）与经典的多相催化相结合，可以应用，以克服上述一些问题。在本文中，我们试图用典型的例子来说明EPOC如何在环境重要的反应（氧化，还原等）中发挥作用。结果表明，EPOC在环境问题，特别是在气体排放处理技术方面具有广阔的应用前景。EPOC的使用可能是真正有用的，因为我们可以提高催化活性，改变所需产品的选择性，并同时控制在给定的电催化过程中的反应速率。
Heterogeneous Catalysis and Electrocatalysis can be used very effectively on air pollution control. Air emissions coming either from mobile sources or from stationary sources, including volatile organic emissions, nitrogen oxides, hydrocarbons and carbon monoxide could be well converted to harmless non-pollutants at reasonable temperatures with cost-effective systems utilizing heterogeneous catalysis and suitable catalysts. Some of the disadvantages of conventional heterogeneous catalysts are the high production cost (since most of them are metal supported catalysts), the short life time (due to the catalyst deactivation) and the weakness to control their activity during the catalytic process. A new phenomenon of Solid State Electrochemistry called Electrochemical Promotion of Catalysis (EPOC) combined with classical heterogeneous catalysis could be applied in order to overcome some of the above problems. In this paper we are trying to show with characteristic examples how EPOC could be useful in environmentally important reactions (oxidations, reductions, etc). The results show that EPOC reveals great perspectives in environmental issues and especially in gas emissions treatment technology. The utilization of EPOC could be really useful since we can increase the catalytic activity, alter the selectivity to the desirable products and simultaneous control the reaction rate during a given electrocatalytic process.
