Stability test of (a) 2Cu/AlOOH-900 catalyst before and after O2-H2O treatment for RWGS reaction; b 5Cu/CeO2 catalyst before and after O2-H2O treatment for CO-PROX reaction. The deactivation-activation process can be repeated through O2-H2O treatment at RT. RWGS reaction condition: 450 °C, weight hourly space velocity (WHSV) = 36000 mL/gcat·h, 24%CO2/72%H2/4%N2, P = 0.1 MPa; CO-PROX reaction condition: 120 °C, WHSV = 36000 mL/gcat·h, 1% CO/0.5% O2/1% N2/97.5% H2, P = 0.1 MPa.
