【 摘 要 】

The isotherms of CO adsorption on the Cu/ZnO sample treated with hydrogen and methanol are investigated.The heats of adsorption of CO on the Cu/ZnO treated with hydrogen at 723 K for 3 h are in the range from 25.7 kJ/mol at �?= 0.8 to 59.8 at q= 0.1, while those on the Cu/ZnO sample treated with methanol at 523 K for 3 h are in the range 30.3 kJ/mol at �?= 0.8 to 99.8 kJ/mol at �? = 0.1. The Cu/ZnO samples treated with methanol have the higher heats of adsorptions than the Cu/ZnO samples treated with hydrogen do. The heats of adsorption at q = 0.1 increase with the methanol treatment time within 30 min and leveled off afterwards.
