    A correlation was established between the OSC of the catalysts and the formation of carbonate species. Nevertheless, there is no correlation between OSC and catalytic activity, with the ceria-based samples showing the highest reaction rate. An optimal platinum crystallite size is required to achieve the highest conversion of acetic acid in terms of turnover frequency values.
