Abstract: Surface systems composed of low-dimensional nanomaterials have been attracted extensive attentions and applied in many fields such as electrocatalysis, magnetism, energy storage and sensing. The enhanced IR absorption and abnormal IR effects are their anomalous IR optical properties. This paper reviews our recent progress in studying the enhanced IR absorption and abnormal IR effects of low-dimensional nanomaterials. The study consists of the systematic preparation of nanometer scale-thin films and nanoparticles and building surface nanostructures that exhibit anomalous IR properties, as well as in the development of surface combinatorial method, etc. The study is of importance in revealing the intrinsic relationship between anomalous IR optical property and nanostructure of low-dimensional nanomaterials, and in developing related fundamentals.
