Acetic acid decomposition on Pt (111) in the presence of co-adsorbed water is a good model system for oxygenate decomposition on Pt (111) in aqueous phase, with application in hydrogen production and biomass conversion. Here, in this study, we present a density functional theory (DFT) theory calculation of how co-adsorbed water affects different bond cleavages of acetic acid decomposition on Pt (111). The presence of co-adsorbed water generally enhances O$$-$$H bond cleavage while inhibiting OC$$-$$O and OC$$-$$OH bond cleavage. The influence of co-adsorbed water on C$$-$$H bond cleavage varies the most and depends on the nature of the transition state and how co-adsorbed water stabilizes the initial and final state. Although these trends are useful as general guidance, they are not sufficient to predict the effect on a complex reaction network such as acetic acid decomposition on Pt (111) which has several parallel reaction paths with similar energies. In the absence of co-adsorbed water, the two lowest energy pathways are decarboxylation (DCX) and decarbonylation (DCN) pathways through a common CH2COO intermediate, in which the DCX pathway (C$$-$$H bond cleavage of CH2COO) is more favorable than DCN pathway (OC$$-$$O bond cleavage of CH2COO). In the presence of co-adsorbed water, the energy difference between Csingle bondH bond cleavage and OC$$-$$O bond cleavage of CH2COO increases, suggesting an increase in the favorability of acetic acid decarboxylation (formation of carbon dioxide) over acetic acid decarbonylation (formation of carbon monoxide) on Pt (111).
