Interfacial engineering of nickel-based catalysts for enhanced performance in dry reforming of methane

Dry reforming of methane (DRM) has garnered significant interest as a promising route for the simultaneous conversion of methane and carbon dioxide into syngas, thereby mitigating greenhouse gas emissions. Ni-based catalysts are widely studied due to their noble metal-like properties and cost-effectiveness, but they suffer from coking and sintering under high-temperature conditions. In this review, we comprehensively examine recent advances in the rational design of Ni-based catalysts through interfacial engineering strategies, focusing on four key aspects: (i) tailoring the coordination environment of Ni sites; (ii) modifying the electronic properties of nickel species; (iii) enhancing the reactivity of surface and lattice oxygen; and (iv) optimizing the surface chemical environment by gas-mediated treatments. Furthermore, we highlight the critical insights and proposed strategic recommendations for enhancing catalytic performance, energy efficiency, and catalyst durability. This review aims to provide valuable guidance for the development of highly efficient and stable DRM catalysts.
