| Popis: | A Ni nanosheet-coated FeCrAlloy monolith catalyst was successfully prepared using a deposition-precipitation-based “Korea Institute of Energy Research” (KIER) coating method, which provides a uniform coating of highly dispersive Ni catalyst on the metal substrate. The newly developed monolith catalyst showed a higher Ni dispersion and surface area on the substrate as compared to a washcoated monolith catalyst. The Ni nanosheet-coated monolith catalyst exhibited high activity and long-lasting stability at a high space velocity of GHSV = 15,000 h −1 during a natural gas steam reforming reaction for H 2 production. This is mainly attributed to the fact that the uniform and highly dispersed Ni nanosheet catalyst improves the availability of surface active metal sites on the metal substrate. |
