Embodiments described in the patent, grouped by the materials and process steps they use.
2 materials1 process step
Layered MoS₂ powder is dispersed in chlorosulphonic acid (superacid) under argon atmosphere, sonicated, allowed to exfoliate, and subsequently quenched with distilled water to yield a stable aqueous dispersion of exfoliated MoS₂ flakes.
3 materials1 process step
Highly homogenous dispersions comprising varying weight percentages of exfoliated MoS₂ flakes in graphene oxide in DI water were vacuum filtered and then thermally reduced to yield layered freestanding rGO/MoS₂ composite paper electrodes.
Layer stacks claimed or described, ordered top of device to substrate.
