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.

在微通道上装有响应型催化纳米颗粒的新型智能微反应器

如今，尽管新开发的微反应器技术已显示出希望，但对高放热反应进行有效和可靠的控制以有效防止过热甚至爆炸仍然是一项艰巨的任务。在这里，我们报告了一种新型的智能微反应器系统，该系统在微通道上配备了响应性催化纳米颗粒，可通过对反应产生的热量作出反应，对高度放热的反应进行自我调节控制。基于响应式催化纳米颗粒中聚合物网络的收缩/溶胀行为，智能微反应器可以响应反应温度的变化，从而调节热反馈过程中催化颗粒的催化活性。作为突破性的结果，在这种微反应器中进行的高度放热反应可以在自我调节过程中得到很好的控制，而无需任何人工协助，从而有效地确保了反应的安全性。这种智能的响应式催化系统具有很高的潜力，并且作为新一代高效工具具有吸引力，它们具有针对高放热催化反应的自我调节特性。
