Abstract The reactivity of carbonaceous surfaces bears a fundamental role in various fields, from atmospheric chemistry and catalysis to graphene and nanoparticles. This reactivity is mainly driven by the surface chemical composition and by the strength of the interaction between the adsorbates and the surface (physi-/chemisorption). While the surface composition of complex natural samples can be well characterized, adsorption energies (ergo, adsorption processes) of the corresponding adsorbate/adsorbent systems are often overlooked. We propose a novel laser-based method for measuring the adsorption energy of chemical species on various carbonaceous surfaces. The proof of concept of this original method has first been demonstrated by deriving adsorption energies of various systems consisting of polycyclic aromatic hydrocarbons and activated carbon. The great potential of this fast, spatially resolved, and surface-sensitive method, which can also act as a defect density probe at the mesoscale, has been further demonstrated through the study of systems of increasing complexity.

一种基于激光测量碳质表面吸附能的新方法

摘要 碳质表面的反应性在从大气化学和催化到石墨烯和纳米粒子的各个领域都具有重要作用。这种反应性主要由表面化学成分和吸附物与表面之间的相互作用强度（物理/化学吸附）驱动。虽然复杂天然样品的表面组成可以很好地表征，但相应的吸附质/吸附剂系统的吸附能（ergo、吸附过程）往往被忽视。我们提出了一种新的基于激光的方法来测量各种碳质表面上化学物质的吸附能。这种原始方法的概念证明首先通过推导由多环芳烃和活性炭组成的各种系统的吸附能来证明。
