Nevertheless, the widespread adoption of δ-MnO₂ in commercial applications remains hindered by challenges such as insufficient electrical conductivity and instability in its structural integrity throughout charge and discharge cycles. In this study, using KOH solution as the etchant, CNT@K⁺-doped δ-MnO₂ (CNT@KMO) was successfully fabricated, where the CNTs enhance the transport of electron by establishing a conductive network, while the K⁺ from KOH serves as pillars to intercalate into the MnO₂ interlayer, giving rise to a more stable structure. Consequently, the CNT@KMO electrode demonstrates an ideal reversible specific capacity of 306.1 mA h g^-1 after 150 cycles at a current density of 0.5 A g^-1 in a 2 M ZnSO₄+0.2 M MnSO₄ aqueous electrolyte. Furthermore, the electrode exhibits a respectable specific capacity of 100.8 mA h g^-1 with a coulombic efficiency close to 100% at a current density of 5 A g^-1 and exceptional cycling stability more than 2000 cycles.

This work employs density functional theory (DFT) with the PBE + <em>U</em> functional to investigate the adsorption and sensing performance of NO and NO₂ on transition metal (TM)-doped GaN@MoSSe heterostructures. The adsorption energy, charge transfer, electron localization functions, charge density difference, spin density, band gaps and density of states are analyzed. The findings reveal that a transition from physisorption to chemisorption occurs after TM atoms doping. Also, when the surface is embedded with Cu, Fe and Mn atoms, there is a significant improvement in the behavior related to gas adsorption. The bandgap and its variations lead to the change in surface electrical conductivity, thereby affecting the gas sensitivity of the adsorption system. Particularly, the Cu_Ga-GaN@MoSSe and Fe_Ga-GaN@MoSSe systems exhibit improved gas sensitivity toward NO due to their significant band gap reduction. Meanwhile, the Cu_Se−MoSSe@GaN, Cu_Ga-GaN@MoSSe, Fe_Ga-GaN@MoSSe and Mn_Ga-GaN@MoSSe systems also demonstrate enhanced sensing capabilities for NO₂.
