Abstract
Disclosed herein are precursor compounds, composite electrodes comprising the same, and methods of making and use thereof.
Claims20
A composite electrode comprising:
- a MoS2 layer disposed on a substrate;
- wherein the substrate comprises a semiconductor substrate and/or a conductive substrate;
- and
- wherein the MoS2 layer comprises a thermally annealed product of a precursor layer comprising a precursor compound having a formula I:
- [Mo3Sy(S2CNR2)z]X4-z I
- wherein
- y is 4 or 7;
- z is 3 or 4, with the proviso that when y is 7, z is 3;
- R is a substituted or unsubstituted C1-C15 alkyl group, a substituted or unsubstituted C2-C15 alkenyl group, a substituted or unsubstituted C2-C15 alkynyl group, or a substituted or unsubstituted C3-C20 aryl group;
- and
- X is a halide anion, a tetrafluoroborate anion, or a hexafluorophosphate anion.
