Pt-CGO catalysts are widely used for commercial use of diesel reforming. In this study, perovskite-based catalysts were investigated as alternatives to substitute the noble metal catalyst for the ATR of diesel. The investigated perovskite structure was based on LaCrO3. And metals were added at the A-site to enhance oxygen ion mobility, transition metals were doped on the B-site to enhance the reformation. Substituted Lanthanum chromium perovskites were made by aqueous combustion synthesis, which can produce high surface area conveniently. We used perovskite catalyst with Pt-CGO that widely used for commercial catalyst in diesel reforming. We made perovskite, Pt-CGO physically mixture catalyst(1:1 wt%) and compare durability performance with using single catalyst. |
