An ionic liquid/organic solvent mixture was adopted as an electrolyte for the electrochemical reduction of N₂O. The ionic liquid and organic solvent used for the electrolyte were 1-butyl-3-methylimidazolium tetrafluoroborate ([BMIM][BF₄]) and propylene carbonate (PC), respectively. The use of [BMIM][BF₄] in place of aqueous solutions improves the solubility of N₂O and also avoids the hydrogen evolution reaction, which is the main side reaction in an aqueous solution. The low electrical conductivity and high viscosity of [BMIM][BF₄], the main disadvantages in the context of electrochemical reactions, were compensated on introducing PC. The composition of the [BMIM][BF₄]/PC was optimized considering both the electrical conductivity and N₂O stability in the solution. For the optimized [BMIM][BF₄]/PC, a high faradaic efficiency (>90%) was achieved for N₂O reduction to N₂.

离子液体/有机溶剂混合物被用作用于N ₂ O电化学还原的电解质。用于电解质的离子液体和有机溶剂为1-丁基-3-甲基咪唑四氟硼酸酯（[BMIM] [BF ₄ ]）和分别是碳酸亚丙酯（PC）。代替水溶液使用[BMIM] [BF ₄ ]，可以提高N ₂ O的溶解性，并且可以避免作为氢的主要反应的氢生成反应。引入PC可以弥补[BMIM] [BF ₄ ]的低电导率和高粘度，这是电化学反应中的主要缺点。[BMIM] [BF _4的组成考虑到溶液中的电导率和N ₂ O稳定性，对] / PC进行了优化。对于优化的[BMIM] [BF ₄ ] / PC，实现了将N ₂ O还原为N ₂的高法拉第效率（> 90％）。
