Can Doped-MXene-Based Supercapacitors Be the Game-Changer for Future Energy Landscape? A Critical Perspective.

MXene has attracted considerable attention for supercapacitor applications in the past decade owing to its exceptional electrochemical properties. Although major research interests are focused on composite-based MXene, doping engineering of MXene has recently emerged as a promising alternative. This work unveils the potential of doped MXene for supercapacitor applications with a critical perspective.

Effect of synthesis methods on the activity of NiO/CoO as an electrode material for supercapacitor: in the light of X-ray diffraction study.

The formation of heterostructures by combining individual components (NiO and CoO) is a preferred approach to enhance electrochemical performance as it leads to improved charge transfer and surface reaction kinetics. In the present work, a NiO/CoO composite was prepared by two methods. First, neat NiO and CoO were prepared by adopting the hydrothermal method followed by the formation of the composite (i) by a hydrothermal route (NC-Hydro) and (ii) by a calcination route (NC-Cal).

Gallium-based nascent electrode materials towards promising supercapacitor applications: a review.

To meet the energy requirement of the modern era, supercapacitors are promising candidates for energy storage devices, which possess the potential to compete with the future battery technology. To accomplish this pivotal task, it is vital to choose electrode materials that have high power and energy density as well as superb electrochemical stability. For the past few years, the use of gallium-based materials for energy storage applications has attracted attention because of their excellent activity towards electrochemical energy storage applications despite the single oxidation state (, +3 which is redox inactive and does not contribute towards pseudo capacitance).

Visible-light driven Gd2Ti2O7/GdCrO3 composite for hydrogen evolution.

A series of Gd(2)Ti(2)O(7)/GdCrO(3) composites are prepared by solid state combustion method using Gd(NO(3))(3), TiO(2), Cr(2)O(3) as metal source and urea as a fuel. The composites are characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), UV-visible diffuse reflectance spectra (DRUV-vis), Brunauer-Emmett-Teller (BET) surface area measurements, photoluminescence spectra (PL), X-ray photoelectron spectroscopic (XPS) studies, photocurrent measurements etc. The photocatalytic activity of the composites is examined towards hydrogen production without using any co-catalyst under visible light illumination.
