Fuelled by the appearance as a crucial intermediate during in situ decomposition of highly DRM-active LaNiO3 perovskite structures, we show that La2NiO4 can be equally in situ decomposed into a Ni/La2O3 phase offering CO2 capture and release necessary for DRM activity, albeit at much higher temperatures compared to LaNiO3. Decomposition in hydrogen also leads to an active Ni/La2O3 phase. In situ X-ray diffraction during DRM operation reveals considerable coking and encapsulation of exsolved Ni, yielding much smaller Ni crystallites compared to on LaNiO3, where coking is virtually absent. Generalizing the importance of intermediate Ruddlesden-Popper phases, the in situ decomposition of La-based perovskite structures yields several obstacles due to the high stability of both the parent perovskite and the Ruddlesden-Popper structures and the occurrence of parasitic structures.}, cin = {ER-C-1}, ddc = {540}, cid = {I:(DE-Juel1)ER-C-1-20170209}, pnm = {5351 - Platform for Correlative, In Situ and Operando Characterization (POF4-535)}, pid = {G:(DE-HGF)POF4-5351}, typ = {PUB:(DE-HGF)16}, UT = {WOS:000672248500006}, doi = {10.1016/j.apcata.2020.117984}, url = {https://juser.fz-juelich.de/record/893909}, }
