Exploring Dry Reforming of CH4 to Syngas Using High‐Entropy Materials: A Novel Emerging Approach

Abstract The high global warming potential of natural gas methane necessitates its conversion into valuable products, typically through syngas production. Among various technologies for methane valorization, dry reforming of methane (DRM), particularly when integrated with carbon capture, stands out as a prominent method. However, persistent challenges such as the reverse water‐gas shift reaction, coke formation, and sintering associated with methane dry reforming have redirected scientific focus toward multimetallic catalysts with supports or promoters. High‐entropy materials have gained attention as promising catalysts because their flexible composition allows fine‐tuning of lattice oxygen reactivity and catalytic activity. Entropy plays a key role in catalysis, and recent research focuses on the enthalpy–entropy relationship that influences reaction pathways. Alongside entropy, core effects like lattice distortion, sluggish diffusion, and cocktail effects improve catalytic performance by synergistic effects, prevent carbon buildup, and maintain stability at high temperatures, enabling efficient methane conversion. These advancements in high‐entropy materials drive interest in using entropy‐stabilized systems to address the challenges of methane dry reforming. This review summarizes recent advancements in the dry reforming of methane, particularly the integration of carbon capture techniques with dry reforming processes using high‐entropy materials.
