摘要
The efficient catalytic hydrogenation of CO2 to methanol is a promising route for CO2 emission mitigation and utilization. Recently, the Co-In based materials as one of the excellent alternative catalysts for CO2 hydrogenation to methanol have received intense attention. Herein, we developed new and efficient Co-In based catalysts (the composite of Co3InC0.75 and In2O3) by Prussian Blue analogues (PBA) pyrolysis. And a series of Co3InC0.75-In2O3 composites with tunable proportion of Co3InC0.75 and In2O3 has been prepared. The experimental results demonstrate the Co3InC0.75-In2O3 catalysts have high catalytic CO2 hydrogenation performance into methanol, reaching a methanol yield up to 0.62 gMeOHgcat−1h−1 at 300 °C, 5 MPa, 24000 cm3STPgcat−1h−1, and H2/CO2 = 3:1, the high reaction stability and air resistance. The synergetic effects between Co3InC0.75 and In2O3 for the enhanced methanol production were confirmed by a series of characterizations, and a positive correlation between methanol production activity and the fraction of Co3InC0.75/In2O3 was well established.
