Abstract

Engineering and decoration on the surface of metal oxide semiconductor (TiO2) for increasing activity is challenging. Thus a novel method is introduced to determine surface morphology quality subsequently improving the photocatalytic behaviour. TiO2films are fabricated via laser deposition technique at various CdS thickness. Microstructural characterization and optical behaviours are characterized by felid emission scanning electron microscope (FE-SEM) and atomic force microscope (AFM). The hydrophilic property of TiO2/CdS nanocomposite film (NCF) is examined via contact angle measurements. The grain density is found linearly increased with the contact angle. A mutual relationship is revealed between hydrophilic property and crystallization with respect to the CdS thickness. Thus, surface morphology of nanocomposite quality is quantified based on the hydrophilic measurement

Highlights

Titanium dioxide is attractive inorganic solids because of its biologically and chemically inert, abundantly available and cost effective
The aim of the present work is to enhance the performance of TiO2/CdS nanocomposite films (NCFs) surface and photocatalytic activity by controlling the thickness of CdS as doping layer
The grain size of the films doped with CdS to syntheses TiO2/CdS NCFs has a tendency to become bigger at higher CdS thickness

Summary

Introduction

Titanium dioxide is attractive inorganic solids because of its biologically and chemically inert, abundantly available and cost effective. A contact angle method is used as a tool to study surface quality of the nanocomposites films, NCFs. The aim of the present work is to enhance the performance of TiO2/CdS nanocomposite films (NCFs) surface and photocatalytic activity by controlling the thickness of CdS as doping layer. We are presented with a simple and efficient method to evaluate the best surface aggregation of TiO2/CdS NCFs by contact angle method.
