Abstract
Herein, we report the synthesis of Cr incorporated ZnO sheets arrays microstructures and construction of photoelectrode through a direct aerosol assisted chemical vapour deposition (AACVD) method. The as-prepared Cr incorporated ZnO microstructures were characterized by transmission electron microscopy, scanning electron microscopy, energy dispersive X-ray spectroscopy, powdered X-ray spectroscopy, X-ray photoelectron spectroscopy and UV-Vis diffused reflectance spectroscopy. The Cr incorporation in ZnO red shifted the optical band gap of as-prepared photoanodes. The 15% Cr incorporation in ZnO has shown enhanced PEC performance. The AACVD method provides an efficient in situ incorporation approach for the manipulation of morphological aspects, phase purity, and band structure of photoelectrodes for an enhanced PEC performance.
Highlights
Another way to improve PEC water-splitting performance by reducing electron recombination is to design new complex structural architecture of photoelectrode
The as-fabricated Cr incorporated ZnO thin films were characterized by powdered X-ray diffraction spectroscopy, field emission scanning electron microscopy (FESEM), energy-dispersive X-ray spectroscopy (EDX), transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS) and diffused reflectance spectroscopy
The morphology of as-fabricated thin film microstructures was explored through FESEM and TEM
Summary
Another way to improve PEC water-splitting performance by reducing electron recombination is to design new complex structural architecture of photoelectrode. The absorption edge of ZnO appears at 391 nm that shifted towards higher wavelength with increasing Cr content i.e. 400 nm for 15% Cr incorporated ZnO, resulting in the decrease in band gap of as-fabricated thin films.
