Title: Activity and structure of perovskites as diesel reforming catalysts for solid oxide fuel cells.

Abstract

Recent progress in developing perovskite materials as more cost-effective catalysts in autothermal reforming (ATR) of diesel fuel to hydrogen-rich reformate for solid oxide fuel cell (SOFC) application is reported. Perovskite-type metal oxides with B sites partially exchanged by ruthenium were prepared and evaluated under ATR reaction conditions. The hydrogen yield, reforming efficiency, and CO{sub x} selectivity of these catalysts were investigated using diesel surrogate fuel with 50 ppm sulfur. The catalyst performances have approached or exceeded a benchmark, high-cost rhodium-based material. In parallel with the reactivity study, we also investigated the physical properties of B-site doped perovskites and their impact on the reforming performance using various characterization techniques such as BET, X-ray powder diffraction, temperature programmable reduction, scanning electron microscopy, and synchrotron X-ray absorption spectroscopy. We found that ruthenium is highly dispersed into perovskite lattice and its redox behavior is directly associated with reforming activity.
