Graphite work function
WebAccording to them, the work function of rGO can be tuned up to ∼2.5 eV by varying the composition of oxygen-containing functional groups. Sygellou et al. 12 studied the variation in work function of GO via three different reduction processes. They found the work function decreases by ∼1 eV between GO and reduced GO. WebMay 12, 2024 · In this work, we have studied the surface of graphite felt electrodes by different methods in terms of morphology and chemistry to understand the electrocatalytic activity. We then defined the interaction between the surface and the electronic structure with particular emphasis on the work function and valence band. ... The low-work …
