• temperature of the high-HAB region (above 10 mm) is lower because of the relatively faster carbon formation process due to the abundance of carbon sources and the adequate temperature, specifically within the fuel stream flow. Contrarily, in the low-HAB region (below 9 mm), there is no growth within the fuel

• catalyst surface, which consequently facilitates high catalytic activity and low catalyst deactivation. The mechanism of DRM and carbon formation and reduction are reviewed. This work further explores how different constraints, such as the synthesis method, metal loading, pretreatment, and operating

• conditions, influence the dry reforming reactions and product yields. In this review, different strategies for enhancing catalytic activity and the effect of metal dispersion on Mg-containing oxide catalysts are highlighted. Keywords: carbon formation; catalyst development; dry reforming of methane

• , and Ir, exhibit high activity and resistance toward carbon formation [19][20][21]. However, these noble metals are associated with high cost and low availability, so non-noble metals, such as Ni [18][22][23][24], Fe [25][26][27][28], and Co [29][30] are most often used. Among the non-noble metals, Ni
