只有47%的肥料氮被植物吸收，而大约40%的肥料氮流失到环境中，重新转化为无反应的大气氮素，这极大地影响了全球氮循环，包括增加了氨合成的能源消耗，以及饮用水中硝酸盐的积累。在这封信中，我们提供了一种机械化学法合成无机镁钙盐-尿素离子共晶体，以获得稳定性增强的氮肥。通过减少或消除溶液处理和蒸发的需要，所提供的无溶剂力化学合成可以导致更大的制造工艺可持续性。NH3排放测试表明，与纯尿素相比，尿素离子共晶体能够减少对环境的NH3排放，从而为氮循环管理的可持续全球解决方案提供了影响。
Only 47% of the total fertilizer nitrogen applied to the environment is taken up by the plants whereas approximately 40% of the total fertilizer nitrogen lost to the environment reverts back into unreactive atmospheric dinitrogen that greatly affects the global nitrogen cycle including increased energy consumption for NH3 synthesis, as well as accumulation of nitrates in drinking water. In this letter, we provide a mechanochemical method of inorganic magnesium and calcium salt-urea ionic cocrystal synthesis to obtain enhanced stability nitrogen fertilizers. The solvent-free mechanochemical synthesis presented can result in a greater manufacturing process sustainability by reducing or eliminating the need for solution handling and evaporation. NH3 emission testing suggests that urea ionic cocrystals are capable of decreasing NH3 emissions to the environment when compared to pure urea, thus providing implications for a sustainable global solution to the management of the nitrogen cycle.
