Hydrogen evolution is consistently higher than acetone evolution in both samples and increases even more, when carbon monoxide evolution is observed as well, indicating thermal decomposition processes. At 600 °C, no acetone is formed anymore and only carbon monoxide and hydrogen can be detected. Hydrogen evolution is approximately five times higher than carbon monoxide evolution and carbon monoxide evolution is 33 % and 39 % of 2-propanol feed at the beginning of the experiment in mol•min -1 with carbon monoxide being the only carbon species released at this temperature. Consequently, the remainder of carbon has to be deposed on the catalyst's surface, which is qualitatively confirmed by ex-situ XRD after the experiment (see tables 3 and 4).
