Integrated Microwave Synthesis and Catalytic Application of Transition Metal Carbides for Rapid Hydrazine Decomposition
Abstract
Abstract Transition metal carbides were rapidly synthesized by microwave irradiation and evaluated as catalysts for the decomposition of hydrazine hydrate by microwave irradiation. Phase composition, morphology, and distribution of the elements were studied using X-ray diffraction and SEM/EDS. The prepared materials based on β-Mo₂C exhibited porous morphologies, and Cu modification provided the highest catalytic activity. Cu-Mo₂C achieved 100% hydrazine conversion at 450 W within 3 min. The improved performance was due to the uniform distribution of Cu and accessible Cu-Mo₂C interfaces. Comparable activities of single- and double-irradiated β-Mo₂C showed that catalytic performance was more influenced by catalyst morphology and architecture of the interface than by bulk-phase purity. The results demonstrate the effective integration of rapid microwave synthesis and catalytic hydrazine conversion.
