Figure 1.

In situ XRD of the bulk‐intermetallic Pd_xZr_y catalyst at ca. 20 °C and during DRM at 800 °C. A gas flow of 2 mL min⁻¹ of CH₄/CO₂ (ratio 1:1) at ambient pressure with a heating rate of 20 K min⁻¹ was applied. Initial state at room temperature: a), bottom spectrum and b), left side; in situ DRM state: a), top spectrum and b), right side.
