Ex-situ spectro-BCDI of CO2 reduction catalyst nanoparticles

Converting CO₂ to value‐added chemicals via catalysis is a key approach to mitigating emissions. Cu, PdPt, and NiFe alloy nanoparticles (NPs) are promising CO₂ reduction catalysts and subjects of ongoing and future in‑situ operando 3D spectro‑BCDI experiments. This state‑of‑the‑art tool correlates NP structural (lattice strain, defects, facets, morphology) and chemical (composition, oxidation states) features, guiding catalyst design. To exploit this, we propose a preliminary ex‑situ study of these NP catalysts at BM02—a beamline specialized in anomalous x‑ray diffraction (including DAFS and resonant scattering)—to generate a baseline dataset for refining spectro‑BCDI analysis protocols.
