摘要: The binding energy for CO2 adsorbed on Cu (100) has been determined by use of TPD and was found to increase with increasing coverage from 25 to 30 kJ mol− 1. The CO2 desorption temperature increased from 86 to 90 K with increasing coverage. The dissociative adsorption of CO2 on Cu (100) at a CO2 pressure of 990 mbar and a temperature range of 475–550 K has been investigated by XPS. The dissociative adsorption of CO2 was found to have an activation energy of 93±5 kJ mol− 1 and to have a sticking …
