Fig. 6From: Effect of vacancies and edges in promoting water chemisorption on titanium-based MXenesEnergy gain per molecule as a function of the water coverage for a Ti2CO2 and b Ti2C(OH)2. Two contributions to the total energy (black line) are considered. The interaction between water molecules is in light blue. The interaction between the water layer and the substrate is colored depending on the type of termination. The dashed line indicates the interaction value for a single water molecule, corresponding to a coverage of 6%. Solid lines between points are guides to the eyeBack to article page
