Finally, different methods of controlled gas release were investigated using CO2-loaded porous liquid samples, as measured by collecting and measuring the amount of gas released (Error! Reference source not found.4; Figure , Tables ). This included irradiation at 365 nm while stirring, sonication in a room temperature water bath, heating and stirring at 80 °C, and chemical displacement via the addition of chloroform. Increasing the temperature of the sample to 80 °C resulted in the highest quantity of CO2 being released, displacing 98.6±3.9 mol/gPL. Both sonication and UV irradiation performed equally well, displacing 82.2±7.3 mol/gPL and 79.8±8.7 mol/gPL, respectively. Chemical displacement performed the least well of the methods tested, displacing 75.9 mol/gPL. In all cases, the amount of gas released by the porous liquid was significantly higher than that of the neat ionic liquid and irradiation showed the largest difference, with a 426% increase. The other release methods ranged from a 115% to 341% increase over the neat ionic liquid. This correlates with an 81% difference in the quantity released between the porous liquid and the ionic liquid on irradiation, compared to 65% for sonication, 61% for thermal release, and 77% for chemical displacement (Table ). This shows that photochemical release is almost as effective as traditional methods, such as temperature swing, in terms of the total amount of gas released. However, when the difference in gas release is compared, UV-irradiation is the most effective in terms of the working capacity, with thermal release the least effective due to it being a non-specific trigger that is commonly used for liquid sorbents.
