Our strategy begins with MoS2 sheets decorated with Pt NPs and their scrolls (called MoS2@Pt scrolls) with intrinsic bending strain (2.4%) to provide the phase transition from the 2H to the 1T phase (28%). MoS2@Pt scrolls have the amount of Pt NPs (8.3 wt%) and high catalytic activity (39 mV per decade).
