Nickel-based perovskite catalysts with iron-doping via self-combustion for hydrogen production in auto-thermal reforming of Ethanol

Steam reforming of acetic acid over coal ash supported Fe and Ni catalysts

“…Ni and Fe have proven to be highly active for reforming. Fe also acts as a promoter for other active metals, such as Ni, by lowering reduction temperature, promoting reactant absorption [37], inhibiting CH 4 production [35], stabilizing catalyst structure, limiting metal particle growth, and preventing carbon deposition [38].…”

“…The high loading levels of Ni in conventional Ni-based catalysts renders them very expensive for reforming purposes, validating the potential use of 10NieFe/ZDA as an alternative catalyst [33,37]. Moreover, the preparation costs of 10NieFe/ZDA are lower than those of Ni/Ref Ash catalysts with 15% Ni loading, because Fe is less expensive than Ni and the cost of coal ash support is negligible.…”

Recent Advances in Hydrogen Production Via Autothermal Reforming Process (ATR): A Review of Patents and Research Articles

“…The impregnated catalyst exhibited lower catalytic activity and lower coke resistance in comparison to the perovskites. ATR of ethanol over Ni doped LaNiO 3 was examined by Huang et al, 2012 [133]. The doping of Ni retained the perovskite structure in the form of solid solution La (Ni, Fe) O 3 , with formation of metal Ni and formation of Ni-Fe alloy after the reduction.…”

A modified sol–gel method for low-temperature synthesis of homogeneous nanoporous La1−x Sr x MnO3 with large specific surface area

“…As a catalyst, the catalytic activity and stability are prerequisite, strongly relating to its morphology, particle size distribution, and crystallinity, which are determined by the preparation method adopted [9]. Traditionally, the preparation method (e.g., sol-gel [10], citrate complexation [11], solid-state reaction [12], co-precipitation [13]) involve in high-temperature solid-state reactions, leading to the destruction of pore structures and hence to low surface areas (\25 m 2 /g). That would greatly hinder their practical applications in heterogeneous catalysis.…”
