Conversion of CO2 to Multi-carbon Compounds over a CoCO3 Supported Ru-Pt Catalyst Under Mild Conditions

The catalytic hydrogenation of CO₂ to multi-carbon compounds under mild conditions would not only provide value-added products, but also benefit for the reduction of CO₂ emission if hydrogen derives from renewable energy sources. Herein, we report CoCO₃ supported Ru and Pt nano-particles, which could catalyze hydrogenation of CO₂ to produce higher hydrocarbons(C₂-C₂₆) and higher alcohols(C₂OH-C₆OH) at low temperatures of 80-130℃. The selectivity for C₂₊ compounds reached 81.1% at 80℃, which was the highest value reported so far. This work provides a promising catalyst for highly selective converting CO₂ and H₂ to C₂₊ compounds at low temperatures.
