ZnZrOx solid solution is a promising catalyst for the hydrogenation of CO2 to methanol, but precise design nanostructure enhance catalytic performance remains significant challenge. Herein, ZnZrOx-based (ZnZrOx-MD) nanoparticle with uniform metal dispersion and remarkable activation ability was developed via calcination metal–organic frameworks [MOFs, viz., PCN-223(Zn)] mixed (Zr Zn) as precursors. It found that ZnZrOx-MD outperformed its counterparts prepared using traditional deposition–precipitation method (ZnZrOx-TD). Furthermore, effects micromorphology crystal composition on were systematically investigated. Comprehensive characterization results reveal contained abundant oxygen vacancies, large specific surface area, dispersion, which collectively contributed excellent performance, resulting in high methanol selectivity 77.2% at 320 °C. In situ DRIFTS experiments confirm mechanism over catalysts involved initial formation HCOO* species, followed by subsequent generate CH3O* ultimately produce methanol. Overall, this work highlights potential benefits MOFs thermal decomposition precursors fabrication solid-state unique properties.

Abstract Indium‐zirconium (InZrO x ) and zinc‐zirconium oxides (ZnZrO have emerged as highly selective stable catalysts for CO 2 hydrogenation to methanol, a versatile energy carrier. However, the disparity in synthesis methods, catalyst formulations, structures previously studied precludes quantitative comparisons between two families. Herein, rigorous framework is pioneered benchmark InZrO ZnZrO materials prepared by standardized flame spray pyrolysis platform, enabling consistently high surface areas tunable metal speciation ranging from isolated atoms (<5 mol%) predominantly nanoparticles (>10 mol%). Isolated indium zinc species are commonly identified be optimal activity methanol selectivity their respective families, maximizing H activation abilities. outperforms across speciations less structure sensitive, deviations atomic dispersion detrimental on performance former. Focusing representative featuring saturation of species, higher 5 mol% over its counterpart linked differences oxygen vacancy chemistry, lower degree product inhibition, more facile formate intermediate methoxy. The identification reactivity descriptors governing both families facilitates development unified guidelines designing reducible oxide catalysts.
