  1. Catalytic Scrubber

    Linked via "Palladium ($\text{Pd}$)"

    Precious Metal Catalysts
    Platinum ($\text{Pt}$)/), Palladium ($\text{Pd}$)/), and Rhodium ($\text{Rh}$)/) are frequently employed due to their high activity across a broad temperature range. These metals are typically dispersed onto high-surface-area ceramic or metallic monolithic supports (e.g., cordierite or stainless steel foils).
