我们开发了一种新颖的水热氧化还原反应方法，制备了氧空位缺陷浓度可调的锰钾矿型八面体分子筛纳米棒。我们证明了一个巨大的OVD效应的OMS-2的催化性能。提高OVD浓度可显著提高晶格氧的活性，从而大大提高催化剂对苯氧化的活性。
We have developed a novel and facile approach of hydrothermal redox reaction to prepare cryptomelane-type octahedral molecular sieve (OMS-2) nanorods with tunable concentration of oxygen vacancy defects (OVDs). We demonstrate a giant OVD effect on the catalytic performance of OMS-2. Increasing the OVD concentration considerably enhances the lattice oxygen reactivity, thus tremendously promoting the catalytic activity for the oxidation of benzene.
