综述了使用二氧化碳作为氧化剂直接转化甲烷的最新趋势。虽然使用分子氧的氧化涉及各种中间体的连续氧化以产生二氧化碳并且对所需产物表现出较低的选择性，但使用二氧化碳作为氧化剂的甲烷活化消除了这种连续氧化并且具有相当大的前景。在这种情况下，负载型金属催化剂可以促进甲烷的干重整，并且已经发现结构化氧化物催化剂能够使用二氧化碳作为氧化剂将甲烷偶联到C2产物上。本综述还总结了有关使用非常规工艺与二氧化碳结合进行甲烷活化的最新研究。
Recent trends on the direct conversion of methane, employing carbon dioxide as an oxidizing agent are reviewed. While oxidation using molecular oxygen involves the sequential oxidation of various intermediates to generate carbon dioxide and exhibits low selectivity for the desired products, methane activation using carbon dioxide as an oxidant eliminates this sequential oxidation and has considerable promise. In this context, supported metal catalysts can promote the dry reforming of methane, and structured oxide catalysts have been found to enable methane coupling to C2products, using carbon dioxide as the oxidizing agent. This review also summarizes recent research regarding the use of nonconventional processes for methane activation in conjunction with carbon dioxide.
