Despite appealing supercapacitive properties, the flexible asymmetric supercapacitor devices (FASCs) are still suffering from low mass loading and limited operating voltage, leading to unsatisfactory energy densities. Herein, we introduced a high-voltage anodic electro-deposition process (AED) which is a novel avenue enabling the synthesis of hiera...

In this work, a honeycomb-like ZnO/SnO2 nanocomposite was synthesized on nickel foam (NF) using a single-step hydrothermal route for achieving good electrochemical performance. The as-prepared electrode showed an excellent electrochemical performance in 3 M KOH electrolyte, a superior specific capacitance (C-s) of 2307 F g(-1) and good stability, 7...

Exploring robust, highly efficient, and cost-effective non-noble metal electrocatalysts for replacing Pt in hydrogen evolution reaction (HER) is of great significance. In this study, we skillfully synthesized binary transition-metal (i.e., nickel and iron) phosphosulfides on nickel foam (NiFeSP/NF) via a sulfuration/phosphorization treatment of bim...

All-solid-state supercapacitors constructed with effectively composited materials are required urgently for the next generation of portable electronic devices. Herein, two dimensions of materials (carbon nanotubes and exfoliated MoS2) are used as basic building blocks for deposition of zero-dimensional birnessite-MnO2 nanoparticles. The obtained te...

Well dispersed vanadium nitride (VN) nanoparticles were successfully prepared by nitridation of Zn-3(OH)(2)(V2O7)center dot(H2O)(2) nanosheets followed by alkaline leaching. ZnO derived from Zn-3(OH)(2)(-V2O7)center dot(H2O)(2) during nitridation process acted as a clapboard to prevent VN nanoparticles from growing up and agglomerating. In addition...
