Effect of Pt cluster size on CO2 adsorption and activation on (110) and (100) γ-alumina surfaces: insights from DFT using a periodic boundary approach

We performed a structural investigation on the adsorption and activation of CO2 molecules on different sized Pt clusters to study the effect of Pt cluster size on CO2 adsorption. Several Ptx clusters (x = 1–5 and 13) were analyzed to represent metal dispersion on surfaces and nanoscale metal cluster...

الملخص:We performed a structural investigation on the adsorption and activation of CO2 molecules on different sized Pt clusters to study the effect of Pt cluster size on CO2 adsorption. Several Ptx clusters (x = 1–5 and 13) were analyzed to represent metal dispersion on surfaces and nanoscale metal clusters. For (110) γ-alumina surfaces, the Pt2 cluster site was the most stable. In addition, the Pt3 cluster site was the most stable for CO2 adsorption on Pt/Al2O3. Charge transfer from Pt clusters to CO2 was critical for CO2 activation.
