국문 초록

Dry reforming of methane (DRM) has attracted much attention as a promising carbon utilization technique because it converts CH4 and CO2 into syngas (H2 and CO2) simultaneously. However, its commercialization is limited by carbon deposition and metal sintering under high temperature reaction conditions. In this review, we discuss the main physicochemical factors governing the activity and stability of DRM catalysts, such as strong metal-support interactions (SMSI), metal dispersion, particle size, basicity, and oxygen storage capacity (OSC). We also review structural design strategies including core-shell, perovskite, double metal, exsolution, and atomic layer deposition (ALD)-based catalysts to improve catalyst stability and coke resistance. Future DRM catalyst development is expected to be important as an integrated design strategy that simultaneously achieves high activity, stability, and coke resistance through simple individual properties and interaction of catalyst structure.
