The understanding of the detailed surface sites and atomic scale structure of heterogeneous catalysts under reaction atmosphere or conditions is one of the key challenges for catalyst design and development, which is of great significance in the fields of sustainable energy production and conversion, and emission control systems. In this report, we will focus on the discussion of recent findings in the investigation of the surface species in correlation with the atomic structure of Pt (or Pd) alloyed bimetallic/trimetallic catalysts for low-temperature hydrocarbon and carbon monoxide oxidation. In-situ/operando techniques such as Diffuse Reflectance Infrared Fourier Transform Spectroscopy (DRIFTs) and Synchrotron High-Energy X-ray Diffraction coupled with Pair Distribution Function analysis (HE-XRD/PDF) are used for the structural characterization. New insights into the catalytic reaction pathways and the structure-composition-activity correlation will be discussed
