Catalytic Decomposition of Ammonia over Bimetallic CuO/CeO2 Nanoparticle Catalyst
The oxidation of ammonia to nitrogen by selective catalytic oxidation (NH3-SCO) over a bimetallic CuO/CeO2 nanoparticle catalyst at temperatures between 423 and 673K. A bimetallic CuO/CeO2 nanoparticle catalyst was prepared by co-precipitation method at molar ratio of 6:4. This study also considers how the concentration of influent NH3 (C0 = 800 ppm), the space velocity (GHSV = 92000/hr), the r...
متن کاملKinetics of the Catalytic Decomposition of Ammonia over a Bimetallic Copper-cerium Nanoparticle Catalyst
This study examines the kinetics of selective catalytic oxidation of ammonia to nitrogen over a bimetallic copper-cerium nanoparticle catalyst in a tubular fixed-bed reactor. Transmission electron microscopy results showed that the catalyst containing copper and cerium is well dispersed and presents in the form of nano-sized particles. The formation of CuO/CeO2 active sites was confirmed by Fou...
متن کاملPatched bimetallic surfaces are active catalysts for ammonia decomposition
Ammonia decomposition is often used as an archetypical reaction for predicting new catalytic materials and understanding the very reason of why some reactions are sensitive on material's structure. Core-shell or surface-segregated bimetallic nanoparticles expose outstanding activity for many heterogeneously catalysed reactions but the reasons remain elusive owing to the difficulties in experime...
متن کاملAmmonia synthesis over Co-Mo alloy nanoparticle catalyst prepared via sodium naphthalenide-driven reduction.
We report the synthesis of Co-Mo alloy nanoparticles with a uniform distribution of the alloy elements on CeO2via sodium naphthalenide-driven reduction. The resulting sample functions as a highly efficient and stable catalyst for ammonia synthesis. Based on the metal weight, the catalytic activity is ca. 20 times higher than that of Co3Mo3N.
متن کاملCatalytic Ammonia Decomposition over High-Performance Ru/Graphene Nanocomposites for Efficient COx-Free Hydrogen Production
Highly-dispersed Ru nanoparticles were grown on graphene nanosheets by simultaneously reducing graphene oxide and Ru ions using ethylene glycol (EG), and the resultant Ru/graphene nanocomposites were applied as a catalyst to ammonia decomposition for COx-free hydrogen production. Tuning the microstructures of Ru/graphene nanocomposites was easily accomplished in terms of Ru particle size, morph...
