Five polyotype
WebAug 18, 2024 · The reported results show that the 3R polytype is more suitable for the conversion of MoS 2 into the metallic 1T phase, which was attributed to surface oxidation occurring in the 2H polytype. Higher content of the 1T phase then resulted in an overall lower overpotential of −0.25 V vs .
