原子级分散Fe-N-C温和条件下选择性氧化催化特性

An atomically dispersed Fe-N-C catalyst prepared by one-pot mechanochemical process was used for selective oxidation of sulfides and secondary alcohols. The results show Fe-N-C catalyst can selectively transform sulfides to sulfoxides under mild conditions without any over-oxidized sulfones. This process has several advantages such as mild reaction conditions, high reaction speed and satisfactory yields. In addition, this catalyst exhibits high catalytic activity in the oxidation of the secondary alcohols to the related ketones with decent yields. As a heterogeneous catalyst, activity of this atomically dispersed Fe-N-C does not significantly decrease after 5 times of circulation.
