Rational design of deep eutectic solvents with low viscosities and multiple active sites for efficient recognition and selective capture of NH3
Abstract Efficient recognition and selective capture of NH3 is not only beneficial for increasing the productivity of the synthetic NH3 industry but also for reducing air pollution. For this purpose, a group of deep eutectic solvents (DESs) consisting of glycolic acid (GA) and phenol (PhOH) with low...

| description | Abstract Efficient recognition and selective capture of NH3 is not only beneficial for increasing the productivity of the synthetic NH3 industry but also for reducing air pollution. For this purpose, a group of deep eutectic solvents (DESs) consisting of glycolic acid (GA) and phenol (PhOH) with low viscosities and multiple active sites was rationally designed in this work. Experimental results show that the GA + PhOH DESs display extremely fast NH3 absorption rates (within 51 s for equilibrium) and high NH3 solubility. At 313.2 K, the NH3 absorption capacities of GA + PhOH (1:1) reach 6.75 mol/kg (at 10.7 kPa) and 14.72 mol/kg (at 201.0 kPa). The NH3 solubility of GA + PhOH DESs at low pressures were minimally changed after more than 100 days of air exposure. In addition, the NH3 solubility of GA + PhOH DESs remain highly stable in 10 consecutive absorption‐desorption cycles. More importantly, NH3 can be selectively captured by GA + PhOH DESs from NH3/CO2/N2 and NH3/N2/H2 mixtures. 1H‐NMR, Fourier transform infrared and theoretical calculations were performed to reveal the intrinsic mechanism for the efficient recognition of NH3 by GA + PhOH DESs. |
