Abstract
Here we demonstrate for the first time the splitting of dioxygen at RT over distant binuclear transition metal (M = Ni, Mn, and Co) centers stabilized in ferrierite zeolite. Cleaved dioxygen directly oxidized methane to methanol, which can be released without the aid of an effluent to the gas phase at RT.
摘要
在此，我们首次展示了在室温下，稳定于镁碱沸石中的远距离双核过渡金属（M = Ni、Mn和Co）中心对双氧的裂解。裂解产生的双氧直接将甲烷氧化为甲醇，且在室温下无需借助流出物即可将甲醇释放到气相中。
