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.

Abstract High‐entropy perovskite oxides exhibit promising application prospects in the field of electrocatalysis, owing to their flexible elemental composition, plentiful active sites, and superior structural stability. Herein, high‐entropy oxide nanotubes are prepared with La, Nd, Pr, Er, Eu at A‐site by electrospinning as efficient electrocatalysts for nitrate reduction reaction (NO 3 RR). Electrochemical tests demonstrate that LaNd 0.25 Pr Er CuO 4 (LNPEEC NTs) display outstanding NO RR performance, achieving a NH Faraday efficiency (FE NH3 ) 100% −0.7 V versus reversible hydrogen electrode (RHE) yield rate 1378 µg h −1 mg cat. −1.0 RHE , outperforming Nd 2 (NC NTs). Furthermore, LNPEEC NTs also excellent stability even after 10 cycles . X‐ray absorption spectroscopy confirms multi‐component regulation optimizes coordination environment Cu B‐site, increasing unsaturated sites thus providing more sites. Additionally, density functional theory calculations reveal doping rare‐earth elements modulates d‐band center B‐site reduces energy barrier rate‐determining step, enhancing adsorption − promoting performance.
