Abstract
In this work we synthesized the Neodymium Vanadate anchored on GQD decorated silver nanowire for electrochemical water splitting HER and OER. The composite was prepared through simple hydrothermal method and investigated the composite's structural and catalytic qualities. The AgNW@ GQD gave the entire composite a larger surface area and greater structural stability. To generate 50mA cm current density and a low Tafel slope value of 107 mV/dec , NdVO4/AgNW@GQD requires 267 mV of overpotential which is low compared to NdVO4, AgNW @GQD and commercial Pt/C electrode. Additionally, composite was used as an anode material in the OER reaction; however, 150 mV (vs RHE) overpotential was required to produce the current density of 10 mA cm current density, while the tafel slope value is 131 mV/dec .In the long-term chronoamperometric investigation, the current density for HER and OER increased up to 87% and 92%, respectively, over 100 hours, with nearly no changes. Keywords: NdVO4, AgNW@GQD, Water splitting, Electrocatalyst, hydrogen evolution reaction
