Probing catalytic reactions on a catalyst surface in real time is a major challenge. Herein, we demonstrate the utility of a continuous flow millifluidic chip reactor coated with a nanostructured gold catalyst as an effective platform for in situ investigation of the kinetics of catalytic reactions by taking 5-(hydroxymethyl)furfural (HMF) to 2,5-furandicarboxylic acid (FDCA) conversion as a model reaction. The idea conceptualized in this paper can not only dramatically change the ability to probe the time-resolved kinetics of heterogeneous catalysis reactions but also used for investigating other chemical and biological catalytic processes, thereby making this a broad platform for probing reactions as they occur within continuous flow reactors.
实时探测催化剂表面的催化反应是一个重大挑战。在此，我们展示了一种连续流微流控芯片反应器的实用性，该反应器涂有纳米结构的金催化剂，可作为通过原位研究 5-（羟甲基）糠醛（HMF）到 2,5-呋喃二甲酸（FDCA）转化的反应动力学的有效平台，以此作为模型反应。本文提出的这一理念不仅可以极大地改变探测多相催化反应的时间分辨动力学的能力，还可以用于研究其他化学和生物催化过程，从而使该研究成为在连续流动反应器中实时探测反应的广泛平台。
