Flexible hollow Ni/Al2O3 fibers: A sustainable and reusable catalyst for efficient dry reforming of methane
A new type of Ni/Al2O3 self-supporting catalysts, with high specific surface area, was fabricated by blow-spinning technology. These Ni/Al2O3 self-supporting catalysts are hollow flexible fibers and were utilized for the dry reforming of methane. The Ni/Al2O3 catalysts exhibited exceptional catalytic performance, maintaining their activity for over 150-h at a high temperature of 800°C. The Ni nanoparticles disputed on the hollow fibers demonstrated remarkable resistance to sintering and coking during high-temperature catalysis. This was a noteworthy feature, as sintering and coking are common challenges faced by catalysts during high-temperature reactions. Furthermore, the catalysts retained its activity even after a rigorous 150-h test at 800°C, indicating its durability and stability. Importantly, the Ni/Al2O3 self-supporting could be successfully reactivated after the test, further highlighting its reusable nature. This study offers promising new avenues for the development of high-temperature, self-supporting, and reactivatable catalysts.
期刊介绍:
The Journal of the American Ceramic Society contains records of original research that provide insight into or describe the science of ceramic and glass materials and composites based on ceramics and glasses. These papers include reports on discovery, characterization, and analysis of new inorganic, non-metallic materials; synthesis methods; phase relationships; processing approaches; microstructure-property relationships; and functionalities. Of great interest are works that support understanding founded on fundamental principles using experimental, theoretical, or computational methods or combinations of those approaches. All the published papers must be of enduring value and relevant to the science of ceramics and glasses or composites based on those materials.
Papers on fundamental ceramic and glass science are welcome including those in the following areas:
Enabling materials for grand challenges[...]
Materials design, selection, synthesis and processing methods[...]
Characterization of compositions, structures, defects, and properties along with new methods [...]
Mechanisms, Theory, Modeling, and Simulation[...]
JACerS accepts submissions of full-length Articles reporting original research, in-depth Feature Articles, Reviews of the state-of-the-art with compelling analysis, and Rapid Communications which are short papers with sufficient novelty or impact to justify swift publication.
