A Standardized Dataset of CO-TPD Spectra on Transition-Metal Single-Crystal Surfaces

• • The dataset includes 14 transition-metal single-crystal surfaces, enabling cross-metal comparisons of CO desorption behavior and providing a benchmark for theoretical models. • • Normalization preserves essential spectral features such as peak shape, allowing deconvolution of complex TPD spectra from industrial catalysts. • • Experimental parameters, including heating rates, are documented, ensuring reproducibility and facilitating kinetic analysis. • • The standardized protocol for data collection and quality control transforms fragmented graphical data into complete digitized spectral profiles, shifting analysis from isolated peak temperatures to integrated spectral profiles.
