Top views of the relaxed pristine (a1), Au (a2), and Ti (a3) adsorbed M–WS2. Side views of the relaxed pristine (b1), Au (b2), and Ti (b3) adsorbed M–WS2. The big blue and small yellow spheres represent the W and S atoms, respectively. The big yellow and big gray spheres represent the Au and Ti atoms, respectively. Sites 1 and 2 represent the six equivalent hollow site “H” and the top site “T”, respectively.
