[资源] 低温下分子氧催化氧化甲烷的耦联反应

The development of new paths for the selective conversion of methane to value-added chemicals is very important for the optimal utilization of the abundant natural gas, which has methane as the main component. Current technologies for obtaining oxygenates from methane are mainly based on indirect routes via syngas. Obviously a direct selective oxidation process is more attractive from an economic point of view.

We recently developed a catalytic system for the one-pot aerobic oxidation of methane at 80 °C, combining three redox couples Pd2+/Pd0-quinone/hydroquinone -NO2/NO, which creates an electron transfer loop. The activation of methane with Pd2+ initiates an electron transfer chain, which carries the electrons from methane to O2 similar to biological oxidation processes. This is the first example integrating an organic co-catalyst for the selective oxidation of methane, which significantly increases the catalytic efficiency of a transition metal.

daiqiguang(金币+1):谢谢继续关注
呵呵 这篇文献也是中科院大连化物所包信和研究员发表的JASC

很有意思的,尤其是哪个耦合反应的设计非常巧妙!最大创新点!!!!!

对你研究其它领域也有借鉴之用(科学研究的方法)
