Abstract: An electrohydrodynamic (EHD) method results in charge driven droplet fission and volumetric shrinkage of metal dichalcogenide sheet droplets, thus wrinkling individual exfoliated metal dichalcogenide sheets on the nanoscale. For example, the method can be used to activate the basal plane of solution exfoliated, stable 2H reverted sheets of MoS2. In this manner, the basal plane of 2H MoS2 can be strained at an unprecedented scale (3.7%), resulting in charge transport to basal plane defects. The resulting crumpled MoS2 integrates few layer sheets and atomistic defects with nano- and micro-scale ridges and vertices to enable centimeter-length films that elevate the catalytic site count of MoS2 from 1.0×1014 sites/cm2 to 2.93×1017 sites/cm2 (planar 2H vs. crumpled 2H) and a turn-over-frequency (TOF) from 0.016 s?1 to 0.130 s?1.
