“…The essential kinetic and thermodynamic conditions to realize a single semiconductor is still elusive [8]. Photoanodes based on Si and III-V semiconductors have exhibited record STH efficiency value up to 19.3 %, but these materials suffer from poor stability [9]. These semiconductors satisfy a bunch of mandatory conditions, but they are associated with high manufacturing costs.…”

“…Moreover, long-term device durability is compromised due to poor stability in PEC conditions. Earthabundant metal oxides, such as ZnO, TiO2, WO3, α-Fe2O3, and BiVO4, exhibit outstanding properties and can be viable options for PEC cells [9]. They have low processing cost, high stability, low minority carrier diffusion length, high recombination, and low light absorption.…”

In this paper, Au plasmons and their synergistic effects with ZnO nanorods (ZNs) have been investigated for photoelectrochemical (PEC) water splitting application. Au plasmons and ZNs are deposited electrochemically. Au modified nanostructures have absorption in the visible region as plasmons enhance charge transfer and inhibit charge recombination. ZNs modified with Au (deposition duration 60 s) has a photo-current density of 660 μA cm -2 , at a bias of 1.0V/SCE. X-ray diffraction and scanning electron microscopy were used to study the structure and surface morphology of fabricated photoanodes. UV-Visible absorption and Photoluminescence spectroscopy were used for optical characterization. We have recorded current-voltage measurements and photo-conversion efficiency measurements to substantiate our observations of the synthesized photoanodes for prospective application in PEC splitting of water. We have also carried out Mott-Schottky, and electrochemical impedance spectroscopy analysis. The analysis reveals that Au modified ZNs based photoanodes are a better proposition than their bare counterparts for PEC water splitting application.
