Bane and boon of oxygen mediating the performance of nickel catalysts in dry reforming of methane

Caption

Heterogeneous catalysts are often dynamic under operation. Now, the mechanism of CH4 dry reforming on Ni is studied by in situ microscopy and spectroscopy, revealing the formation of metastable surface nickel–oxygen structures from CO2 dissociation that exhibit different catalytic properties and induce rate oscillations.
