“…36 The possible factors responsible for the improvement in the kinetics of V 2 O 5 after the addition of MWCNT are: firstly, the increase in surface area and defects which provides more active sites and improves the catalytic activity as reported. 15,41 Moreover, the addition of MWCNTs improves the conductivity, which ultimately facilitates the charge transfer rate of the electrode for LIBs as reported. 37 Thirdly, the structural stability of the V 2 O 5 /MWCNT hybrid system keeps the electrode mechanical strength and provides electron transport pathways.…”

A series of Pd nanoparticles supported on V2O5 immobilized on functionalized carbon, %Pd (1, 3, and 5) and %V2O5 (10, 20, and 30), were prepared by sodium borohydride‐assisted microwave polyol synthesis for glycerol oxidation reaction (GlyOR) in an alkaline medium. Electrocatalysts loading, temperature, V2O5 immobilization, and their synergistic effect on the electrocatalytic performance are systematically studied. The electrocatalysts' morphology and electronic properties were investigated using X‐ray diffraction, Fourier transform infrared spectroscopy, scanning electron microscopy, Transmission electron microscopy, and X‐ray photoelectron spectroscopy. A significantly improved GlyOR is observed with increased V2O5 content and Pd percentage. The 5%Pd/30%V2O5–fAC showed the highest mass activity of 2157.3 mA.mg‐1Pd, a more negative onset potential of 0.62 VRHE, versus the commercial equivalent, and possessed high stability and durability. The increase in electrocatalytic activity is attributed to the effective immobilization of V2O5 on fAC efficient synergism between Pd and V2O5, strong metal support interaction (SMSI), and great exposure of the electroactive sites. The results herein contribute significantly to the understanding of the physicochemical and electrochemical effects of metal oxide immobilization, microwave irradiation, %Pd/%Metal oxide optimization, and SMSI on metal oxide‐carbon hybrid electrocatalysts for GlyOR, opening new avenues for fabricating high‐performance direct alkaline glycerol fuel cells.

“…V 2 O 5 nanospheres with a diameter of about 450 nm and shell thickness of 50 nm delivered ultrahigh reversible capacity (327 mAh g −1 at 0.1 A g −1 ), and excellent rate (146 mAh g −1 at 20 A g −1 ) and cycling behavior (147 mAh g −1 after 6000 cycles at 10 A g −1 ; 122 mAh g −1 after 10,000 cycles at 15 A g −1 ), indicating superior performance as compared with commercial V 2 O 5 , when applied for aqueous zinc ion batteries [ 22 ]. In contrast with aqueous zinc ion batteries, there are more recent reports on aqueous lithium ion batteries (i.e., mesoporous nanoflowers [ 23 ] and triple hollow shell [ 24 ] V 2 O 5 structures), giving motivation to researchers to work more intensively on multivalent systems.…”

Research efforts have been focused on developing multivalent ion batteries because they hold great promise and could be a major advancement in energy storage, since two or three times more charge per ion can be transferred as compared with lithium. However, their application is limited because of the lack of suitable cathode materials to reversibly intercalate multivalent ions. From that perspective, vanadium pentoxide is a promising cathode material because of its low toxicity, ease of synthesis, and layered structure, which provides huge possibilities for the development of energy storage devices. In this mini review, the general strategies required for the improvement of reversibility, capacity value, and stability of the cathodes is presented. The role of nanostructural morphologies, structure, and composites on the performance of vanadium pentoxide in the last five years is addressed. Finally, perspectives on future directions of the cathodes are proposed.
