英文摘要	The ultimate objective of chemical conversion is to achieve 100% selectivity from catalysis, and this is also a prodigious challenge for the conversion of light paraffins into olefins, because it involves controlled activation of highly stable aliphatic C-H bonds. Herein, we show that metal-free boron nitride (BN) nanosheets not only enable the oxidative dehydrogenation of ethane to ethylene exclusively at near 10% conversion, but they also deliver a remarkable 60% selectivity at an ethane conversion of 78% and remain stable over 400h at 575 degrees C. Our operando infrared spectroscopy and O-18 isotope tracer study explicitly demonstrates that B-O(H) active sites are formed at the edges of BN through the aid of ethane, and the dehydrogenation circle is completed over these B-O sites by the assistance of O-2.
