Powder X-ray diffraction (PXRD)

X-ray diffraction and scattering

CuCo-THQ powder · Nanosheet

Cu-THQ and CuM-THQ PXRD compared with simulated Cu-THQ pattern; broad 8 deg and 16 deg peaks attributed to limited long-range order.

Geometry: powder
Context: mixed-metal target compared with pristine Cu-THQ
Measurement source: p004 · 3.1 Synthesis and characterization of photocatalysts · Fig. 1d and Fig. S6
