Relevant gas-surface reactions exhibit complex kinetics. Reaction yields and selectivity could significantly improve through new studies based on the systematic variation of surface active sites, tested under the very same conditions. Here we propose curved crystals as the best platform to perform such systematics, which in turn allow one to better resolve fundamental surface properties and to reveal new phenomena. Suchability is demonstrated here in the model CO/Pt system. We curve a Pt crystal around the high-symmetry (111) direction and carry out photoemission scans on top. This renders the spatial core-level imaging of CO adsorbed on a ”tunable” vicinal surface, allowing a straightforward visualization of the rich phenomenology of CO chemisorption at steps and terraces. Through such photoemission images one c an probe a characteristic elastic strain variation at stepped surfaces, and unveil a subtle stress-release effect on clean and CO-adsorbed vicinal planes. Finally, these results o ff er the prospect of applying the curved surface approach to rationally investigate the catalytic activity of surfaces under real pressure conditions.
