Cover Story: Novel yolk@shell morphology has been successfully applied to produce Ni/ZnO@SiO2 and tested against benchmark systems such as Ni/CeO2 and Ni/Al2O3 in the DRM as a direct route for CO2 conversion. Although the Ni/ZnO@SiO2 material displayed middling performance compared to the reference materials, the morphology was found to successfully protect the active phase from sintering, while maintaining high levels of conversion for an extended duration that far surpassed the two reference materials. The yolk@shell material demonstrated impressive performance for over 180 hours and maintained a high H2/CO ratio throughout, showcasing the viability of this new nano-engineered catalyst for chemical CO2 recycling.
