چکیده انگلیسی


• Deposition-precipitation-based KIER(Korea Institute of Energy Research) coating method.
• Ni nanosheet monolith catalyst was prepared by KIER coating for H2 production.
• KIER coating provides a uniform coating of Ni catalyst on the FeCralloy monolith.
• KIER-coated monolith showed better catalytic performance than washcoated monolith.

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 H2 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.
