Hydrothermal synthesis and characterization of nanocrystalline zinc vanadate (Zn2V2O7) on graphene oxide scaffolds

Hydrothermal synthesis and characterization of nanostructured nickel vanadate for supercapacitor and photocatalytic applications

“…NiVO 3 can also react with H 2 O 2 to produce HO• 2 and •OH radicals by equations (10) and (11), in addition to the photochemical synthesis of •OH [46]. As indicated in equation (12) [47], H 2 O 2 may also accept the photoproduced electrons, preventing the electron hole from recombining and facilitating the production of more •OH radicals. Electronic configurations in semiconductor heterojunctions may be split into three distinct classes: straddling, staggered, and fractured.…”

“…Pseudocapacitive materials, mostly transition metal oxides and electrically conductive polymers, could reach the same energy density as batteries and the same cycle life and power density as EDLCs. RuO 2 , NiO, MnO 2 , and V 2 O 5 are all examples of transition metal oxides with high theoretical pseudocapacitance [12][13][14][15] due to their many oxidation states for oxidation and reduction. For their high theoretical specific capacity and outstanding electrochemical reversibility, vanadium-based materials were among the most promising electrode materials for use in supercapacitors.…”

“…5 Furthermore, the combination of graphene with transition metal oxides can result in unique structural and functional properties, making them ideal candidates for the development of high-performance devices. 6 The synthesis of these composites can be achieved through various methods, such as sol−gel 7 and hydrothermal techniques, 8 which can lead to different morphologies and properties. Additionally, the application of these composites in sensing devices has gained particular attention due to their high sensitivity and selectivity toward various gases and vapors.…”

Synthesis and Characterization of Ferric Vanadate Nanorods for Efficient Electrochemical Detection of Ascorbic Acid

“… 15 Lakshmana Naik and Bala Narsaiah reported that Zn 2 V 2 O 7 can be synthesized by employing a hydrothermal method on the graphene oxide scaffolds. 16 The literature 17 also reports the synthesis of CeVO 4 nanoparticles by using a variety of techniques, such as ultrasonic, hydrothermal, sol–gel, coprecipitation, microwave irradiation, solvothermal, and sonochemical methods. Although the majority of these methods can produce CeVO 4 nanoparticles with precise sizes and shapes, the hydrothermally produced Co 3 V 2 O 8 thin nanoplates were reported to work well as cathode materials for LiBs.…”
