Tuning the morphology and size of NiMoO4 nanoparticles anchored on reduced graphene oxide (rGO) nanosheets: The optimized hybrid electrodes for high energy density asymmetric supercapacitors

Highly Sensitive, Wide-Sensing-Range rGO/NiMoO4@CMF Pressure Sensor Based on Biomimetic Mimosa Flowers for Health Monitoring and Human–Computer Interaction

“…The X-ray diffraction (XRD) pattern of NiMoO 4 @CMF sponge obtained using XRD analysis corresponds to PDF#13-0128, proving that NiMoO 4 is successfully synthesized. A weak and broad diffraction peak corresponding to (002) was observed for rGO/NiMoO 4 @CMF at 2θ = 26°, proving the successful synthesis of rGO. Figure l shows the spectrum of Ni 2p, where the two peaks of the Ni 2p 3/2 energy level are located at 856 and 862.4 eV, representing the Ni 2+ and Ni 3+ states, respectively.…”

Validating superior electrochemical properties of Ti3C2 MXene for supercapacitor applications through first-principles calculations

“…The fabricated electrode consistently maintains its low resistance throughout the test, indicating a continuous and stable progression of redox reactions over the course of these 5000 cycles. We have compared our work (stability of fabricated electrode) with already reported literature 53,56,57,[63][64][65][66][67][68][69][70][71][72][73] illustrated in Fig. 8.…”

Recent advances in Ni-materials/carbon nanocomposites for supercapacitor electrodes

“…Using NiMoO 4 /rGO as the (+) electrode in supercapacitors combined with AC as the (−) electrode led to the high-power density. 76 ZnFe 2 O 4 /NiMoO 4 nanosheet/rGO-NF as the cathode and MOF-derived hollow porous carbon as the anode was used in the supercapacitor leading to a high energy density of 58.6 W h kg −1 at a power density of 799 W kg −1 with prolonged cycling. 77 Polyaniline/NiFe 2 O 4 /rGO hydrogel nanocomposites on carbon cloth showed high characteristics that led to the high properties in the corresponding supercapacitors attributed to its well-designed 3D microstructure and diffusion-controlled mechanism.…”
