Iron/vanadium co-doped tungsten oxide nanostructures anchored on graphitic carbon nitride sheets (FeV-WO₃@g-C₃N₄) as a cost-effective novel electrode material for advanced supercapacitor applications

Abstract

In this work, we studied the effect of iron (Fe) and vanadium (V) co-doping (Fe/V) and graphitic carbon nitride (g-C3N4) on the performance of tungsten oxide (WO3) based electrodes for supercapacitor applications.

Proceeding of catalytic water splitting on Cu/Ce@g-C3N4 photocatalysts: an exceptional approach for sunlight-driven hydrogen generation

“…The EDX analysis of Cu/Ce@g-C 3 N 4 confirmed the presence of carbon, nitrogen, copper and cerium. 54 The trace amounts of oxygen (O) detected in the analysis indicate the presence of Ce in an oxide form; our EDX results match with the FTIR findings. The EDX examination verified the successful synthesis of Cu/Ce@g-C 3 N 4 .…”

Graphitic Carbon Nitride (g-C3N4): A Proficient Electrode Material for Flexible Supercapacitors

“…In several other strategies such as involving porous, ultrathin g-C 3 N 4 nanosheets uniformly decorated with NiCo 2 S 4 nanoparticles or be it iron/vanadium co-doped tungsten oxide nanostructures anchored on graphitic carbon nitride sheets, in each case, the superior heterostructure formation ensured effective heterojunctions formation that not only escalated the pseudocapacitance, but also significantly reduced the agglomeration issues, along with creating suitable provision for enhancing the effective surface area to the electrolytic ions through enhanced availability of greater density of redox sites, shorter but wider ion-diffusion channels, significant enhancement of conductivity. All these inspiring results collectively prompted upgrading of the overall electrochemical performance in this system [90,113] . energy densities, have successfully demonstrated their extreme capabilities to exhibit stable capacitive responses even under severe bending conditions [114] .…”

“…Enhancement in the cycling stability and electronic conductivity Improved and manifold rise in conductivity, specific capacitance and cyclic stability compared to bare-PANI and binary-PANI/g-C 3 N 4 electrodes [111] Eventually, the high success rates with the varieties of binary nanocomposite electrodes have driven scientists in the designing of varieties of high performing ternary nanocomposite electrodes with the material which have finally displayed unique combination of the complementary properties of the components [107][108][109][110][111][112][113] . For example, very recently, a marked enhancement in electrochemical output in terms of enhanced charge storage behaviour, augmented rate capacity and distinct reduction in equivalent series resistance, as indicated in Figure 6, were observed while making a comparative study on the relative electrochemical responses between RuO 2 / graphene aerogel (RGA) binary nanocomposite and the ternary composite of RuO 2 /g-C 3 N 4 @graphene oxide aerogel (RCGA) respectively.…”

Integration of Polymorphic CoxSey on MXene-Incorporated Self-Templated Three-Dimensional Graphene Foam to Augment Supercapacitor Performance through Componential and Structural Modifications

“…These problems can be resolved by searching for alternate energy resources and developing low-cost energy storage systems (ESSs). Supercapacitors (SCs) are one of the attractive classes of electrochemical energy storage systems (EESSs). , SCs stand out among EESSs because of their inimitable benefits such as quick release of stored charge, fast charging rates, good cyclic stability, and pollution-free operation . Therefore, it is of great interest among researcher communities to develop more efficient novel electrode materials for SC application.…”
