3.6. Cu-OMS-2 stability evaluation
TG-DSC, XRD and TEM techniques were used to evaluate the
stability of the used Cu-OMS-2 catalyst (Supplementary data,
Figs. S4–6). As shown in Fig. S4, there is no obvious mass loss or
exothermal peak below 400 °C, which suggests that no carbon is
deposited on Cu-OMS-2 catalyst during the reaction. The three
weight loss  steps and the endothermic peaks observed  after
500 °C are caused by phase transformation of manganese oxide
into lower oxidation state because of lattice oxygen loss [19]. As
shown in Fig. S5, the characteristic XRD peaks of the Cu-OMS-2 cat-
alyst before and after reaction are almost identical, which means
that the structure and particle size of used catalyst remain the
same during reaction. Fig. S6 shows the TEM image of the used
Cu-OMS-2 catalyst with the short nano-rod morphology. From
the TG-DSC, XRD and TEM characterization, it can be concluded
that the Cu-OMS-2 catalyst has a robust stability under the reac-
tion condition.
