Abstract Long‐term stability of catalysts is an important factor in the chemical industry. This often underestimated academic testing methods, which may lead to a time gap field catalytic research. The deactivation behavior industrially relevant Cu/ZnO/Al 2 O 3 catalyst for synthesis methanol reported over period 148 days time‐on‐stream (TOS). process was investigated by combination quasi situ and ex analysis techniques. results show that ZnO most dynamic species catalyst, whereas only slight changes can be observed Cu nanoparticles. Thus, this driven moieties. Our findings indicate interfacially mediated between ZnO.
