Operando-SSITKA (Mass spectrometry-DRIFTS) and other isotopic experiments were employed to investigate the steam reforming of acetol on 10-wt% Ni/La2O3-Al2O3 at 500 °C. A large concentration (1 1) participates in the reaction path of H2 formation, while a significantly larger amount (H-content larger than 1.4 mmol H g−1) appeared as inactive species. The nature of the majority of active intermediates comprised of -CHx and -CxHy formed on both the Ni and support phases, and which are associated with a small mean rate constant (kapp = 0.075 min−1) towards H2(g) formation (D2O-SSITKA).
