The CO2 activation process has been investigated on the palladium-indium (PdIn) (111) alloy surface using ambient pressure scanning tunneling microscopy (AP-STM) and synchrotron-based X-ray photoelectron spectroscopy (AP-XPS). Pd In atoms diffuse onto topmost layer after annealing at 840 K, which adopts intermetallic PdIn geometries in an ultrahigh vacuum. AP-STM reveals that interfacial Pd-InOx nanostructures are created by dissociative adsorption under CO2(g) environments even 300 K. Synchrotron-based AP-XPS measurements support idea observed induces InOx segregation PdIn(111) dissociated atomic oxygen from CO2. After all, gas molecules simultaneously adsorb oxygen-terminated sites of nanoclusters to produce carbonate species. Our situ observations indicate restructuring metastable may provide active for efficient activation, contributing rational catalyst design toward sustainable utilizations.
