Key Points

Metal-support interaction plays a critical role in the stability of nickel catalysts during methane reforming.
Key evidence shows that deactivation of Ni/Al2O3 catalysts is linked to carbon deposition and sintering.
Assessment using nickel-based catalysts focuses on dry reforming of methane for better fuel production.
Findings highlight the importance of optimizing metal-support interactions for catalysis efficiency.

Implication

Analysis reveals that metal-support interaction affects catalyst stability in methane reforming, suggesting performance improvements.

Abstract

Ni-based catalysts play a key role in the dry reforming of methane (DRM). However, catalyst deactivation due to carbon deposition, exacerbated by nickel nanoparticle sintering, remains a significant challenge. Inhibiting...
