A porous graphene–NiFe₂O₄nanocomposite with high electrochemical performance and high cycling stability for energy storage applications

Abstract

It is well agreed that supercapacitors form an important class of energy storage devices catering to a variety of needs. However, designing the same using eco-friendly and earth abundant materials...

Vanadium doped CaTiO3 cuboids: role of vanadium in improving the photocatalytic activity

“…3a and b ). 46,47 The BET surface area of 1.0 V was found to be 21.78 m 2 g −1 which is higher in comparison to CaTiO 3 (15.88 m 2 g −1 ), which enables the efficient adsorption and degradation of the pollutants by enhancing the surface-active sites. 48 The pore size distribution was determined using the Barrett–Joyner–Halenda (BJH) method.…”

“…The nitrogen adsorption-desorption isotherms indicated a type IV pattern with the hysteresis loops resembling type H3 (P/Po > 0.4), revealing the presence of slit like pores (Figure 3a and Figure 3b). 46,47 The BET surface area of the 1.0 V was found to be 21.78 m 2 /g which is higher in comparison to CaTiO3 (15.88 m 2 /g), which enables the efficient adsorption and degradation of the pollutants by enhancing the surface-active sites. 48 The pore size distribution was determined using the Barrett-Joyner-Halenda (BJH) method.…”

Rhodium doping augments photocatalytic activity of barium titanate: effect of electronic structure engineering

“…S6 and S9 † ). 46 The BET surface area was found to be 7 m 2 g −1 for the 0.5 Rh sample, which is higher than that of pure BaTiO 3 (4.5 m 2 g −1 ). This higher surface area of the 0.5 Rh sample will be highly beneficial for the effective adsorption and degradation of the pollutants.…”

Vanadium nitride nanoparticle decorated N-doped carbon nanotube/N-doped carbon nanosheet hybrids via a C3N4 self-sacrificing method for electrochemical capacitors

“…† It is clear that our sample exhibits relatively good electrochemical stability among these electrode materials, which is close to the stability of metal-oxide/graphene nanocomposites. 41,42 The EIS plots and Bode plots given in Fig. 6e and f were further performed to reveal the ion/electron transport properties within VN, NCNT/NCN, and VN/NCNT/NCN electrodes.…”
