Novel Activity of TiO2 for Catalytic Conversion of CO and H2O to Alcohols in the Presence of K2CO3

In the presence of K2CO3, TiO2 shows good catalytic activity and stability for the alcohols synthesis from CO and H2O. CO conversion of 7.6% and the STY of MeOH (about 24 mg g−1 h−1) and EtOH (about 8 mg g−1 h−1) are obtained under reaction conditions of T=573 K, P=0.5 MPa, CO flow rate of 30 ml min−1 and CO/H2O = 3/2 during the period of 12 h to 44 h time-on-stream.
