Light‐Driven Metal Exsolution‐Redissolution of High‐Entropy Oxide Enabling High‐Performance Dry Reforming of Methane

Advanced Materials, Journal Year: 2025, Volume and Issue: unknown

Published: April 7, 2025

Abstract Solar‐driven dry reforming of methane (DRM) is attractive for syngas production as an energy‐efficient and environmentally friendly process. However, the remaining challenges low yield coke‐induced inability in this route severely limit its applicability. Here, a light‐induced metal exsolution‐dissolution strategy reported using high‐entropy oxide (HEO) support highly active durable photothermal DRM. As evidenced by structural characterizations theoretical simulations, process triggers chemical looping oxygen vacancies on HEO, which CH 4 activated to CO H 2 lattice while from can fill vacancy release CO. Such pathway greatly improves product formation coking resistance, overcoming limitations. result, optimized CoNiFeZnCr‐HEO supported Rh nanocomposite achieves high /CO 0.242/0.246 mol g −1 h with balance selectivity 0.98 impressive long‐term stability (200 h). The ≈300 450 times higher than that quaternary ternary oxides‐based catalysts, respectively. This work paves way new insights into light‐driven DRM highlights integration dynamic surface evolution molecular activation enhance catalytic performance.
