The catalytic conversion of CO2 to CO through hydrogenation has emerged as a promising strategy for utilization, given that serves valuable C1 platform compound synthesizing liquid fuels and chemicals. However, the predominant formation CH4 via deep over Ru-based catalysts poses challenges in achieving selective production. High reaction temperatures often lead catalyst deactivation changes selectivity due dynamic metal evolution or agglomeration, even with classic strong metal–support interaction. Herein, we have developed FeOx/Ru/Rutile multilayer epitaxial structure by depositing FeOx layer onto epitaxially grown RuO2 nanolayers on surface rutile nanoparticles. This transformed into which Ru nanoparticles were decorated layers ultrastable metal-support interaction (SMSI). Subsequently, decoration effectively shifted dominant product from 95% during hydrogenation. Remarkably, this exhibits exceptional stability can be operated stably at 550 °C long time without apparent deactivation. Compared observed supported nanoparticles, between maintains their electronic states different temperatures. Furthermore, Ru–FeOx inhibits H2 activation capability, adsorption, subsequent CO. transformation employed here, utilizes initial structures, applied construct SMSI enhance catalysts' performance.
