Highly-dispersed ZrOx modulates C–O bond activation for boosting CO2 hydrogenation to higher alcohols

Abstract

This work reports an efficient strategy for modulating C–O bond activation during CO₂ hydrogenation to C₂₊OH over the Zr–KCuFe catalyst, achieving a space–time yield of 96.7 mg g⁻¹ h⁻¹ at 320 °C. A small amount of highly-dispersed ZrO_x promotes non-dissociative activation of CO, driving C₂₊OH synthesis with 1.54 times higher activity than unpromoted KCuFe.
