Abstract

Ammonia (NH₃), as a promising hydrogen carrier, is favored by researchers because of its high hydrogen content (17.8 wt%), easy liquefaction, high safety, and zero carbon molecules. In this study, MOF derivatives FeNi @ NC with different Fe and Ni ratios are synthesized by calcining FeNi-MIL-101 at high temperature. Their performance in the ammonia decomposition reaction is investigated when the molar ratio of Fe to Ni is 6:4, catalyst exhibits the highest adsorption sites, facilitating the adsorption of reactive species. At 650 °C and an air velocity of 30,000 mL h⁻¹g-1 cat, the ammonia decomposition and conversion rate reaches 98 %, and the H₂ production rate is 32.82 mmol H₂ g-1 cat min⁻¹. Under the condition of 600 °C and 60000 mL h⁻¹g-1 cat, the activity of the catalyst is maintained for more than 120 h, with high ammonia decomposition efficiency and catalyst activity life.

期刊介绍： The journal provides an international medium for the publication of theoretical and experimental studies and reviews related to the electronic, electrochemical, ionic, magnetic, optical, and biosensing properties of solid state materials in bulk, thin film and particulate forms. Papers dealing with synthesis, processing, characterization, structure, physical properties and computational aspects of nano-crystalline, crystalline, amorphous and glassy forms of ceramics, semiconductors, layered insertion compounds, low-dimensional compounds and systems, fast-ion conductors, polymers and dielectrics are viewed as suitable for publication. Articles focused on nano-structured aspects of these advanced solid-state materials will also be considered suitable.
