We present a combined theoretical and experimental study on weak chemical complexation between PH(3) and a few selected Cu(I)- and Al-based ionic liquids (ILs). PH(3) molecules were found to covalently bind with the cationic sites of the ILs. Effects of cations, anions, ion pairing, and solvents on the binding strength were systematically examined. The weak coordination of PH(3) on the ILs allows the PH(3) gas to be stored at near ambient conditions with a high capacity.
我们提出了 PH(3)与几种选定的 Cu(I)和 Al 基离子液体 (ILs)之间弱化学络合的理论和实验综合研究。发现 PH(3)分子与 ILs 的阳离子位点共价结合。系统研究了阳离子、阴离子、离子对和溶剂对结合强度的影响。PH(3)对 ILs 的弱配位作用使得 PH(3)气体能够在接近环境条件下以高容量储存。
