不同反应物/吸收产物/中间态吸附在碳纳米管/S掺杂碳纳米管上的吸附能
Materials | MEA | CO2 | MEACOO− | MEAH+ | MEA_CO2 | MEA+COO− | MEACOO−_MEAH+ | |
Ead(CNTs)/(kcal·mol−1) | −3.728 | −1.489 | − | −57.228 | −5.582 | −3.528 | −3.531 | |
Ead(S-CNTs)/(kcal·mol−1) | −2.229 | −0.242 | −26.322 | −56.306 | −2.484 | −2.748 | −5.846 | |
Note: After adsorption of the absorption product MEACOO− by the carbon nanotubes, the structure was then optimised so that MEACOO− decomposes into MEA and CO2. |
