“…Various metal oxides supported zeolite have been widely investigated for light alkane (i.e., methane, ethane, propane) conversion, including precious metal Pt [18,19] and transition metal Zn [20][21][22][23][24][25], Ga [26][27][28][29][30], Mo [31,32], Co [33], Zr [34][35][36] oxides, etc. Moreover, metal modification also has a potential effect on the acidity of ZSM-5.…”

“…Previous study shows that Co and Fe in transition metals exhibit well performance on oxidative dehydrogenation of higher alkanes. To compare the difference of catalytic effect between Cr, Co and Fe on the reaction between ethane andCO 2 , the catalytic performance of different transition metal catalysts with different temperature is displayed in Figure .…”

“…Pure iron is known to suffer from runaway coking under PDH 44,60 conditions, while other Fe-based materials, such as Fe 3 C 44 and FeS, 50,51 have shown high coke resistance. Here, we perform GCMC and ab initio thermodynamics analyses to better understand why these materials are resistant to coke formation.…”

“…Coke formation on catalyst surfaces is a major cause of catalyst deactivation in several industrial reactions involving hydrocarbon-rich environments, such as Fischer-Tropsch synthesis, [33][34][35][36] methane reforming, [37][38][39][40] CO 2 reduction, 41 fluid catalytic cracking, 42,43 and hydrocarbon dehydrogenation. 44,45 Various strategies have been developed to suppress coke formation, typically by adding promoters and dopants, [46][47][48] forming metal phosphides or sulfides, [49][50][51][52] forming nitrides or carbides, 44,53 or alloying with less carbophilic metals. [54][55][56] The particular interest in this work is the suppression of coke formation during nonoxidative propane dehydrogenation (PDH).…”
