摘要：NOVELTY - An ammonia synthesis and dissociation catalyst comprises 0.5-20 wt.% laminated silicate as carrier to load 80-99.5 wt.% active component ruthenium. The carrier is muscovite or sodium (Na)-montmorillonite. The particle size of ruthenium is 1-16 nm. USE - An ammonia synthesis and dissociation catalyst used in preparing zero-cyclooxygenase (Cox) hydrogen, and catalyzing hydrogen and nitrogen (claimed). ADVANTAGE - The catalyst has good activity and stability in preparing zero Cox hydrogen. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method of preparing ammonia synthesis and dissociation catalyst by dipping precursor solution containing active component ruthenium and laminated silicate, dipping, stirring, and setting aside for 8-14 hours at room temperature; and drying at 20-120 degrees C for 2-12 hours, reducing, and activating for 2-5 hours at 200-600 degrees C under hydrogen atmosphere. The precursor solution is ruthenium chloride (RuCl3) solution.
