“…In the XRD pattern for pure GNP, a single high intense diffraction peak can be observed at 26.41 as 2q with an inter-spacing of 3.35Å, corresponding to the XRD peak of the (002) crystalline plane of the graphene nanoplatelet. 33 In the XRD pattern for GNP@PANI nanocomposites, peaks corresponding to both GNP and PANI are visible. This result demonstrated that graphene nanoplatelets and polyaniline existed also, whereas an interaction was created between graphene nanoplatelets and polyaniline.…”

“…However, only during the last few years researchers have looked into MoO x nanowire/ fiber preparation. The liquid phase approach is a traditional method for synthesizing various MoO x nanowires; typical synthesis approaches including the hydrothermal/solvothermal method, vapor deposition, and sonochemical strategy are mostly introduced for synthesis methods [19][20][21][22]. Ghorai et al [23] designed bismuth molybdate (α-Bi 2 Mo 3 O 12 phase) nanowires using a pyridine intercalative sonochemical route.…”

Transition metal oxides are found to have overwhelming applications in energy, electronics, catalytic, and bio-and micromechanical systems. A recent report emphasized the current advancements in molybdenum oxide (MoO x) nanowire synthesis and the corresponding surface-functionalized nanostructured materials based on our previously reported investigations. The preparation of the nanowires and their applications were systematically summarized. MoO x nanowires combined with substrates exhibited remarkable performances for high energy storage and power densities with high stability. In addition, the review concluded the future advancements of MoO x nanowires.

“…These results are attributed to a synergistic effect between PANI and metal oxides. [8][9][10][13][14][15] There are several proposed mechanism for the explanation of this synergism. One of them of is the creation of a conductive network between Ni(OH) 2 and PANI particles.…”

This study has been conducted for investigating the contribution of polyaniline (PANI) to the electroactivity of nickel hydroxide (NH) by using a combination of electrochemical, structural and morphological characterization techniques. NH, PANI and nickel hydroxide/PANI composite (NHP) electrodes were produced on nickel foam substrates. Electrodeposition and chemical bath deposition methods were used for the preparation of NH and PANI, respectively. All the electrochemical experiments were conducted in alkaline solutions. NH and PANI were used as reference materials and exhibited properties in accordance with the literature. Namely, for NH electrode capacity decayed by cycling because of the phase transformation from α to β-Ni(OH) 2 , and particles growth from 350 to 850 nm. Also, flower-like structure of the as prepared Ni(OH) 2 faded after 2000 cycles. On the other hand, PANI electrode although exhibited a decrease in the conductivity because of its degradation retained its capacity over cycling because of swelling and shrinking that led to an increased surface area. Composite electrode consisting of PANI and NH resulted in an improvement of capacity retention. At the beginning of cycling capacitance of the composite electrode was 0.64 F/cm 2 , capacity decreased to 0.47 F/cm 2 after 500 cycles then, continuously increased and finally reached to 0.54 F/cm 2 after 2000 cycles. Presence of PANI in combination with NH, limited the particle growth and contributed to the preservation of flower like structure of NH. Contrary to both NH and PANI electrodes, charge transfer resistance of NHP exhibited a decrease with cycling indicating a synergy between NH and PANI in addition to morphological changes.
