Direct oxidation of methane to methanol is a long-standing challenge in the heterogeneous catalysis community. This communication demonstrates that water, not dioxygen, is the main source of the oxygen present in the methanol produced in the partial oxidation of methane to methanol over Cu-SSZ-13 in a continuous flow reactor. This is confirmed by experiments performed in the absence of molecular oxygen and the use of 18O labeled water. These findings should lead to new approaches for improving the partial oxidation properties of copper zeolites.

水是在 Cu-SSZ-13 上的流动反应器中部分氧化甲烷时产生甲醇的氧源

将甲烷直接氧化成甲醇是多相催化领域长期存在的挑战。该通讯表明,在连续流动反应器中,通过 Cu-SSZ-13 将甲烷部分氧化为甲醇,所产生的甲醇中存在的氧气主要来自水,而不是分子氧。在没有分子氧和使用 18O 标记水的情况下进行的实验证实了这一点。这些发现将为改善铜沸石的部分氧化性能提供新的方法。
