Abstract Efficient recognition and selective capture of NH 3 is not only beneficial for increasing the productivity synthetic industry but also reducing air pollution. For this purpose, a group deep eutectic solvents (DESs) consisting glycolic acid (GA) phenol (PhOH) with low viscosities multiple active sites was rationally designed in work. Experimental results show that GA + PhOH DESs display extremely fast absorption rates (within 51 s equilibrium) high solubility. At 313.2 K, capacities (1:1) reach 6.75 mol/kg (at 10.7 kPa) 14.72 201.0 kPa). The solubility at pressures were minimally changed after more than 100 days exposure. In addition, remain highly stable 10 consecutive absorption‐desorption cycles. More importantly, can be selectively captured by from /CO 2 /N /H mixtures. 1 H‐NMR, Fourier transform infrared theoretical calculations performed to reveal intrinsic mechanism efficient DESs.
