采用可控气氛电子显微镜、热重分析和流动反应器等实验技术研究了铂与乙烯和乙炔相互作用形成积碳的过程。发现为了在金属上产生显著量的碳，必须在存在或添加的氢的情况下进行反应。在本研究中，我们将注意力集中在反应中涉及的所有步骤，包括发生在金属-气体界面的步骤：碳通过金属颗粒的扩散
A combination or experimental technigues including controlled atmosphere electron microscopy, thermogravimetry, and flow reactor studies have been used to study the formation of carbon deposits resulting from the interaction or platinum with ethylene and acetylene. It was found that in order to produce significant amounts or carbon on the metal it was necessary to perform the reaction in the presence or added hydrogen. In this investigation we have focused attention on all of the steps involved in the reaction, including those which occur at the metal-gas interface: diffusion of carbon through the metal particles
