Conversion of CO_(2) to Multi-carbon Compounds over a CoCO_(3) Supported Ru-Pt Catalyst Under Mild Conditions

The catalytic hydrogenation of CO_(2) to multi-carbon compounds under mild conditions would not only provide value-added products, but also benefit for the reduction of CO_(2) emission if hydrogen derives from renewable energy sources. Herein, we report CoCO3 supported Ru and Pt nano-particles, which could catalyze hydrogenation of CO_(2)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 CO_(2)and H2 to C2+ compounds at low temperatures.
