Hierarchical Structured SrV2O6/2D-V2CTX MXene Nanohybrid Material for Robust and High-Capacity Aqueous Zn-Ion Batteries

“…Field-emission scanning electron microscopy (FESEM, Carl Zeiss (USA) Model: Sigma with a Gemini column) and transmission electron microscopy (TEM, Model: JSM-7600F) were used to analyze the morphologies of the generated products. The elemental compositions and oxidation states were observed by energy-dispersive X-ray analysis (EDS, Bruker (Germany), Model: Nano XFlash Detector) and X-ray photoelectron spectrometer (XPS, Kratos Analytical Ltd. Ultra DLD) …”

Construction of a binder-free PANI-CQD-Cu electrode via an electrochemical method for flexible supercapacitor applications

“…In recent years, supercapacitors (SCs) have attracted much attention owing to their unique properties such as high power density, superior cycling stability, quick charge–discharge processes and simple fabrication. 1–3 Particularly, flexible supercapacitors (FSCs) have more significant advantages such as flexibility, high energy density and light weight. Moreover, FSCs have better capacitance and electrochemical activity 4–6 due to the synergistic effect and larger surface area of electrode materials prepared by a combination of conducting polymers, 7 metal oxides 8,9 and carbon-based 10,11 materials.…”

Preparation of nickel foam modified by multiwalled hollow spheres of NiCo2O4 as a promising non-enzymatic glucose sensor

“…7 Combining nickel with cobalt to form spinel NiCo 2 O 4 for use as an electrocatalyst has received major attention in many electrochemical applications, such as water splitting, supercapacitor, and chemical sensing. 8–14 In addition, one of the key factors to obtain a favourable electrocatalyst for use as a working electrode is by modifying its structure and morphology, which could further affect its sensing performance due to the increase of the electrode's surface area.…”
