Reactant conversion-intercalation strategy toward interlayer-expanded MoS microflowers with superior supercapacitor performance.

In order to avoid the complicated control and fussy procedure associated with foreign species and templates in conventional synthesis strategies, a simple reactant conversion-intercalation strategy is developed to synthesize interlayer-expanded MoS (E-MoS) by employing ammonium thiocyanate converted from a thiourea reactant as intercalator. In this strategy, the thiourea plays a bifunctionality role as reactant and intercalator precursor to ensure embedding into the interlayers of MoS to expand the interlayer spacing. The optimal E-MoS obtained presents superior supercapacitor performance with a specific capacity of 246.
