We design a spontaneously super-hygroscopic alkaline microreactor by photoinduced integration of Zr-MOF catalyst and alkaline poly(dimethylaminoethyl acrylate) onto LiCl-salinized poly(N-isopropylacrylamide) gel, generating a microenvironment with non-volatile polymeric base and non-bulk water for detoxification of a typical nerve agent simulant, dimethyl 4-nitrophenyl phosphate (DMNP), in atmospheric environments. The super-hygroscopic gel with directional microchannels facilitates the absorption, transport and storage of water under different humidities, and exhibits fast hygroscopic efficiency with a high moisture absorption capacity of 6.4 g g^-1. The integrated microreactor achieves simultaneous water uptake and catalytic hydrolysis of DMNP in an atmospheric environment with an initial half-life of ~1.9 h and a final conversion of 95.5%, which is attributed to the synergistic catalytic microenvironment of the exposed Zr-MOF catalyst, the polymeric base, and the water from moist air. This work provides a feasible strategy for designing spontaneously hygroscopic microreactors for detoxifying nerve agent simulants in atmospheric environments.

我们通过将 Zr-MOF 催化剂和碱性聚（二甲氨基丙烯酸乙酯）光诱导整合到 LiCl 盐化聚（N-异丙基丙烯酰胺）凝胶上，设计了一种自发超吸湿碱性微反应器，产生了具有非挥发性聚合物基和非大量水的微环境用于在大气环境中对典型的神经毒剂模拟物 4-硝基苯基磷酸二甲酯 (DMNP) 进行解毒。具有定向微通道的超吸湿凝胶有利于不同湿度下水分的吸收、输送和储存，吸湿效率高，吸湿能力高达6.4  g  g ^-1. 集成微反应器在大气环境中实现了 DMNP 的同时吸水和催化水解，初始半衰期约为 1.9 小时，最终转化率为 95.5%，这归因于暴露的 Zr-MOF 催化剂的协同催化微环境，聚合物基和潮湿空气中的水。这项工作为设计自发吸湿微反应器提供了一种可行的策略，用于在大气环境中解毒神经毒剂模拟物。
