尽管新开发的微反应器技术已显示出希望，但如今有效、可靠地控制高放热反应以有效防止过热甚至爆炸仍然是一项具有挑战性的任务。在这里，我们报告了一种新型智能微反应器系统，在微通道上配备了响应催化纳米颗粒，通过响应反应产生的热量来自我调节控制高放热反应。基于响应催化纳米颗粒中聚合物网络的收缩/膨胀行为，智能微反应器可以响应反应温度的变化，从而在热反馈过程中调节催化颗粒的催化活性。作为一项突破性的成果，在这种微反应器中进行的高放热反应可以在无需任何人工辅助的情况下通过自我调节过程得到很好的控制，有效地保证了反应的安全。这种智能响应催化系统具有很大的潜力，并且作为新一代高效工具具有吸引力，其具有高放热催化反应的自我调节特性。
Nowadays efficient and reliable control of highly exothermic reactions to effectively prevent overheating or even explosions still remains a challenging task, although newly developed microreactor technology has shown promise. Here, we report a novel smart microreactor system equipped with responsive catalytic nanoparticles on microchannels for self-regulated control over highly exothermic reactions by responding to the reaction-generated heat. On the basis of shrinking/swelling behaviors of polymeric networks in the responsive catalytic nanoparticles, the smart microreactor could respond to the change of reaction temperature to tune the catalysis activity of catalytic particles in a thermo-feedback process. As a breakthrough result, highly exothermic reactions carried out in such a microreactor can be well-controlled in a self-regulation process without any manual assistance, efficiently ensuring the safety of the reaction. Such smart responsive catalytic systems have high potential and are attractive as a new generation of efficient tools that feature a self-regulation property for highly exothermic catalytic reactions.
