The poor intrinsic conductivity of MoS2 presents a huge barrier for the exploitation of its versatile properties, especially as an electrochemical capacitor (EC) electrode and hydrogen evolution reaction (HER) catalyst. Toward this challenge, TiN nanorods coated by randomly oriented MoS2 nanosheets (TMSs) are engineered as state-of-the-art electrodes for ECs and HER. In light of the synergistic effects, TMS electrodes show favorable performance as both a binder-free EC electrode and HER catalyst. Importantly, the optimal TMS achieves an areal capacitance of 662.2 mF cm–2 at 1 mA cm–2 with superior rate capability and ultralong cycling stability. As the catalyst for HER in 0.5 M H2SO4, it shows an overpotential of 146 mV at 10 mA cm–2, a favorable Tafel slope, and good electrocatalytic stability. All of the results highlight the favorable integration of TiN and MoS2 and provide clear insight correlating the hybrid structure and the corresponding electrochemical performance.

Currently, transition metal oxides are widely explored as electrode materials for lithium ion batteries due to their remarkably large reversible capacities. However, these materials always suffer from poor conductivities and slow lithium ion diffusion in the lattice. Given this, a distinctive 3D porous network is developed through partial exfoliation of multiwall carbon nanotubes, which can function as not only superior conductive additive but also as an efficient 3D porous scaffold. By self‐assembling with V3O7·H2O nanowires, the hybrid electrode is demonstrated to achieve a significant boost in lithium storage when compared with pristine V3O7·H2O nanowires. This method can provide much inspiration in the construction of high‐performance metal oxides based electrodes.
