New catalysts based on reduced graphene oxide for hydrogen production from ammonia decomposition

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

“…Additionally, the catalytic activity is given by turnover frequency (TOF) [14,67] and it was estimated according to the next equation:…”

Recent progress for hydrogen production from ammonia and hydrous hydrazine decomposition: A review on heterogeneous catalysts

“…Ni metal particles were used as catalysts with MgAl2O4 as supports by Qiu et al [56] for investigation of the support effect on the catalytic decomposition of ammonia. From the catalysts tested Ni/MgAl2O4 -LDH, developed by hydrothermal synthesis, had the best catalytic activity with 88.7% NH3 conversion and a H2 production rate of 1782.6 mmol gcat -1 h - Ru-based catalysts supported on reduced graphene oxide were developed by Pinzón et al [60] for hydrogen generation by ammonia decomposition. The effect of the Ru loading as well as the effect of the amount of the support material were examined.…”

“…At higher temperatures the conversion is higher and in some cases the catalysts achieve almost complete conversion. Even though Ru is a precious and expensive metal, many studies have focused on Ru catalysts due to their excellent catalytic properties [58], [60], [63], [65], [68] . However, other novel catalysts are investigated with promising results for future experiments [56], [59], [61], [64], [71].…”

“…Generally, the most common ones are alumina and silica [63], [69], but other materials are used as well [57]- [60], [67], [71].…”

Non-Thermal Ammonia Decomposition for Hydrogen Production over Carbon Films under Low-Temperature Plasma—In-Situ FTIR Studies

“…Pinzón et al [ 7 ] obtained CO x -free hydrogen by catalytic ammonia decomposition using Ru supported on reduced graphene oxide (rGO). Ruthenium is often used as a catalyst; nevertheless, its cost makes the process unprofitable.…”
