synthesis and characterization of nickel metavanadate (ni3v2o8)-application as photocatalyst and supercapacitor

With the emerging newer energy storage applications, transition metal vanadates are booming up as a better catalyst. among all the transition metal vanadates, nickel vanadate nanoparticles (ni3v2o8 nps), are considered as a promising material with electrocatalytic and photocatalytic activity. we herein report circular and ovular structured ni3v2o8 nps by hydrothermal route without using any capping agent. crystallinity, physical structure and morphology of the prepared samples were studied by xrd, tem, and ft-ir spectroscopy. photocatalytic activity of ni3v2o8 nps was studied by decolorizing industrially hazardous dyes such as malachite green (mg) and methylene blue (mb) dyes under ultra-violet light conditions for a regular interval of time (15 min) to 90 min. the experiment shows decolorization efficiencies as 52.43 and 57.66% for mg and mb, respectively. the electrochemical behaviour of the prepared compound was studied, and energy storage capacity (specific capacitance) was elucidated as 193.5 fg-1 with high reversibility property the material. these results indicated that ni3v2o8 is a promising electrode material for supercapacitor and is an excellent photocatalyst. hence, hydrothermally synthesized ni3v2o8 nps are expected to offer significant insight into their multifunctional applications
