Development of High Throughput Screening Method of Ni-supported Catalysts for the Decomposition of Methane to Hydrogen and Carbon

Abstract

A high throughput screening (HTS) method for identifying supported nickel catalysts for the decomposition of methane was developed. Porous materials such as H-beta(SiO₂/Al₂O₃ = 150), H-beta(25), and H-ZSM-5(90) were highly effective supports for methane decomposition. The total time to find 3 active catalysts among 18 catalysts could be reduced to about one-third of that required with the conventional method. A Ni content of 5-10 mmol g-support^-1 was adequate. The HTS results were consistent with the results obtained using a conventional reactor.
