The PtSn/Al2O3 is a prototypical industrial catalyst for propane dehydrogenation (PDH). However, the local structures of active sites are still inconclusive under operation conditions. Herein, evolutions Pt-Sn centers supported on nano-Al2O3 definitely discerned at atomic level during PDH reaction. By combining complementary in situ characterizations and theoretical calculations, we demonstrate...

Coal is a readily available and inexpensive material. However, its direct use as catalyst still rare, but attractive for practical application. In this paper, coal was directly used the selective oxidative dehydrogenation of propane to propene. It exhibited high selectivity over 90% with yield 8.4% at space velocity (12,000 mL·(h·g-cat)−1). The productivity up 2.84 gC3H6 gcat−1 h−1 obtained pro...
