Self-combustion Ni and Co-based perovskites as catalyst precursors for ammonia decomposition. Effect of Ce and Mg doping

Promotion effects of different methods in COx-free hydrogen production from ammonia decomposition

“…Different proportions of dopants (Ce or Mg) were added to LaNiO 3 perovskite to explore the effect on catalytic performance. 37 Doped perovskite with Ce or Mg content equal to 0.9 (mol mol −1 ) showed 59.1% and 72.3% conversion at the reaction temperature of 350 °C, respectively. The activity comparison between this work and previous work at 350 °C is shown in Fig.…”

Thermocatalytic Ammonia Decomposition – Status and Current Research Demands for a Carbon‐Free Hydrogen Fuel Technology

“…From a rational design perspective, the combination of two active phases with increased and decreased metal-N interactions compared to Ru is the most promising strategy here. So far, many different bimetallic catalyst systems have been investigated, including FeÀ Ni, [67] FeÀ Co, [68] CoÀ Ni, [69] CoÀ Mo [70] as well as noble metal systems (i. e., FeÀ Ru, [55] NiÀ Ru, [71] NiÀ Pt [72] ). For a comparative overview, Khan et al recently summarized the current state of bimetallic catalysts for ammonia decomposition.…”

Ni Nanoparticles Supported on High Surface Area Carborundum for Enhanced Hydrogen Production by Ammonia Decomposition

“…Because of their limited availability, using precious metal catalysts is undesirable. Due to its low cost and strong activity for ammonia decomposition among nonprecious metals, Ni metal has garnered substantial interest as a viable alternative catalyst. − Numerous materials have been investigated as supports for Ni catalysts in ammonia breakdown. SiO 2 , CeO 2 , and Al 2 O 3 are examples of supports with a high surface area that the Ni-based catalytic method prefers. − …”
