A novel laser-based method to measure the adsorption energy on carbonaceous surfaces

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