BN nanosheets (BN) have drawn great attention in heterogeneous catalysis recently, and their defects have a profound effect on the key performance of the catalyst, but it has been overseen and little addressed. Here, three Fe/BN nanosheet (Fe/BN) catalysts were prepared BN with varied B–O surface defects. Fischer–Tropsch synthesis, a key industrial process, was taken as an example. It is found that the rich B–O defects not only resulted in decreased crystal size and low crystallinity of the Fe₂O₃ but also showed enhanced interaction with the active component and support. As a consequence, the three Fe/BN catalysts showed a dramatic difference in catalytic performance. Our studies reported here could be a guide for the rational design of the highly efficient hydrogenation BN-based catalyst.

Fe / BN催化剂对费托性能的支撑作用：表面B–O缺陷的作用

BN纳米片（BN）近年来在非均相催化中引起了极大的关注，其缺陷对催化剂的关键性能产生了深远的影响，但是这种现象已经被忽略并且很少涉及。在这里，制备了三种具有不同B–O表面缺陷的BN的Fe / BN纳米片（Fe / BN）催化剂。以费托合成为关键工业过程为例。发现丰富的B–O缺陷不仅导致Fe ₂ O _3的晶体尺寸减小和结晶度低而且还显示出与活性成分和支持物的增强的相互作用。结果，三种Fe / BN催化剂在催化性能上显示出巨大的差异。我们在这里报道的研究可能是合理设计高效氢化BN基催化剂的指南。
