The catalytic conversion of CO₂ and H₂ into valuable chemicals is a promising alternative to the recent energy and environmental challenges. However, designing an earth-abundant catalyst capable of actively and selectively converting CO₂ into desirable products is yet a challenge. Herein, we report on a facile K-Co-Cu-Al catalyst prepared by a coprecipitation method for CO₂ hydrogenation to higher alcohols (HAs). We investigated different Co:Cu ratios, reduction temperatures, and reaction conditions (temperature, space velocity, and H₂/CO₂ ratio) to tune it, enhancing the selectivity and yield of higher alcohols. Co_1.8Cu_0.9AlO_x (1 wt% K), reduced at 400 °C, exhibits a high HAs selectivity of 44.8% (20.8% for ethanol) and space–time yield of 5.54 mmol·h^-1·gcat^-1 (3.08 mmol·h^-1·gcat^-1 of ethanol), under mild conditions (250 °C, 30 bar, H₂/CO₂ ratio of 1.5, and 14200 mL·gcat^-1·h^-1), which represents one of the best performances among related studies, especially among Co-based catalysts.
