In-situ self-regenerable Fe / Fe₃C – Mo₂C – CNF catalyst was developed and evaluated extensively over 15 cycles of CH₄ – CO₂ assisted biomass reforming. In-situ regeneration was observed through nucleation on carbon saturated Fe₃C_x sites due to abundance of free-C from reaction and undercoordinated carbon in support. Molybdenum existed as stable β-Mo₂C whereas Fe composition changed from Fe° sites to Fe₃C_x. Due to highly dispersed small nanoclusters (< 5 nm) in lower Fe loading catalysts, graphene nanosheets (GNS) synthesis was observed whereas on 5 % Fe catalysts, large agglomerated nanoparticles (∼10 to 20 nm) facilitated CNF / CNT synthesis. Regeneration on 0.5 % Fe occurred through CNF growth while graphene cover regenerated 5 % Fe catalysts. Fe – Mo₂C – CNF catalyzed reactions produce hydrogen rich syngas over 15 cycles with H₂ concentration > 60 % and H₂:CO ratio of 2–4. Hydrodeoxygenation reforming of biomass was typically between 40–60 % of the amount of oxygenates.

开发了原位自再生Fe / Fe ₃ C – Mo ₂ C – CNF催化剂，并在15个循环的CH ₄ – CO ₂辅助生物质重整中进行了广泛的评估。通过在碳饱和的Fe ₃ C _x位上成核观察到原位再生，这归因于反应中游离C的富集和载体中碳的配位不足。钼存在作为稳定的β-沫₂ ç而铁组合物选自Fe°站点成Fe改变₃ Ç _X。由于在较低的Fe负载催化剂中高度分散的小纳米簇（<5 nm），观察到了石墨烯纳米片（GNS）的合成，而在5％Fe催化剂上，大的团聚纳米颗粒（〜10至20 nm）促进了CNF / CNT的合成。0.5％Fe的再生通过CNF的生长而发生，而石墨烯覆盖层再生了5％Fe的催化剂。Fe – Mo ₂ C – CNF催化反应在15个循环中产生富氢合成气，其中H ₂浓度> 60％，H ₂：CO比为2-4。生物质的加氢脱氧重整通常占含氧量的40-60％。
