Fig. 3From: Effect of vacancies and edges in promoting water chemisorption on titanium-based MXenesPerspective view of the optimized configuration of H2O interacting with (a, d) defect-free MXenes, (b, e) surfaces with a vacancy of termination (VT), and (c, f) edge of ribbons. Ti2CO2 (above) and Ti2C(OH)2 (below) are taken as examples. The yellow arrow highlights the presence of the water molecule. Ti atoms are shown in gray, O in red, C in black and H in whiteBack to article page
