结合XPS表征结果，在1催化剂上，主要为Cβ，仅有少量Cα存在；而对于2和3催化剂上则主要为Cα。随着铈锆比的减小，Cα峰呈现增大的趋势，Cβ含量呈现出先减小后增大的趋势。在CH4解离碎片和石墨化的非活性碳物种之间还应有碳的不同聚集程度和不同石墨化程度的中间过渡状态存在,各种形态的碳均应包括在两个较宽的峰中，难于更细地区分。 |

With decreasing ratio of Ce and Zr, the peak of Ca showed increasing trend. By contrast, Cβ content showed a decreasing trend before increase. Carbon distribution under different degrees and transition state of different degrees of graphitization existed between CH4 dissociation of debris and non-activated graphite species. Various forms of carbon should be included in the two wide peaks so that they are difficult to distinguish in detail. |
