Molybdenum single-atom-bridged ReS2–graphene heterostructures for boosting supercapacitor performance

Original language description

Rhenium disulfide (ReS&lt;inf&gt;2&lt;/inf&gt;), a two-dimensional transition metal dichalcogenide (TMD), possesses weak interlayer interactions and tunable band gap, however its limited charge storage and cycling stability hinder its application in supercapacitors (SCs). This work demonstrates a paradigm shift in the performance of ReS&lt;inf&gt;2&lt;/inf&gt; by introducing molybdenum (Mo) single-atom reactive centers, leading to strong interfacial coupling with a nitrogen-doped graphene (GN3). Notably, Mo‑nitrogen bonds are formed enhancing charge storage in the Mo-ReS&lt;inf&gt;2&lt;/inf&gt;@GN3 (MRG-2) heterostructure. The incorporation of Mo also induces p-type doping (beneficial for coupling with the n-type GN3), lowers the band gap, and enhances the activity of the in-plane sulfur atoms. The MRG-2 electrode delivered 87 % and 31 % increase in capacitance compared to pristine ReS&lt;inf&gt;2&lt;/inf&gt; and Mo-ReS&lt;inf&gt;2&lt;/inf&gt;, respectively, along with a four-fold enhancement in electrical conductivity. An asymmetric SC cell using MRG-2 as the negative and NiCo&lt;inf&gt;2&lt;/inf&gt;S&lt;inf&gt;4&lt;/inf&gt;/graphene as the positive electrode achieved exceptional gravimetric (54.3 Wh kg&lt;sup&gt;−1&lt;/sup&gt; at 1.0 kW kg&lt;sup&gt;−1&lt;/sup&gt;), volumetric (110.5 mWh cm&lt;sup&gt;−3&lt;/sup&gt; at 0.940 W cm&lt;sup&gt;−3&lt;/sup&gt;), and areal (54.3 μWh cm&lt;sup&gt;−2&lt;/sup&gt; at 1.0 mW cm&lt;sup&gt;−2&lt;/sup&gt;) energy densities, and remained stable for at least 10,000 cycles. These findings establish interfacial single-atom engineering as a transformative approach to optimizing TMD-based heterostructures for next-generation energy storage technologies.
