Atomic force microscopy (AFM)-based nanoscale infrared (nano-IR) techniques have found extensive application in the fields of chemistry, physics, and materials science, enabling the visualization of nanoscale features that surpass the optical diffraction limit. More recently, tentative investigations have been conducted into the use of these techniques in the field of catalysis, particularly in studying interfacial processes involving molecular monolayer samples. IR nanoimaging and nanospectroscopy offer unique perspectives on catalytic processes. Considering the specific characteristics of catalytic processes, this Perspective highlights the need for and reviews the current status of AFM-based nano-IR techniques for catalysis investigations, which aims to contribute to a deeper understanding of the nanoscale mechanisms underlying the catalytic processes.
基于原子力显微镜（AFM）的纳米级红外（nano-IR）技术在化学、物理和材料科学领域得到了广泛应用，能够实现超越光学衍射极限的纳米级特征的可视化。最近，人们已尝试将这些技术应用于催化领域，特别是用于研究涉及分子单层样品的界面过程。红外纳米成像和纳米光谱为催化过程提供了独特的视角。考虑到催化过程的具体特点，本综述强调了基于AFM的纳米红外技术用于催化研究的必要性，并综述了其现状，旨在有助于更深入地理解催化过程背后的纳米级机制。
