"Oxygen's Impact on Nickel Catalysts in Methane Reforming"
A study on the mechanism of CH4 dry reforming on nickel catalysts reveals the formation of metastable surface nickel-oxygen structures from CO2 dissociation, which exhibit different catalytic properties and induce rate oscillations. Understanding the role of different oxygen species on a nickel catalyst during dry reforming of methane is crucial for designing high-performance catalysts. The study highlights the critical role of dissociative CO2 adsorption in regulating the oxygen content of the catalyst and CH4 activation, providing fundamental insights into the processes occurring at the catalyst surface and how this modulates the catalytic performance during dry reforming of methane.
