Fabrication and Electrical Characterization of Graphene and Graphene-MOx Hybrid Nanostructures for Gas Sensing Applications, Ph.D. Dissertation Sharif University of Technology ; Iraji Zad, Azam (Supervisor) ; Akhavan, Omid (Co-Advisor) ; Gholami, Mohammad Reza (Co-Advisor)
Abstract
In this project, two types of graphene obtained from chemical and chemical vapor deposition (CVD) methods were studied for gas/vapor sensing applications . In chemical method, oxidation and exfoliation of graphite was performed in liquid phase. AFM, XPS, Raman spectroscopy and Uv-visible spectroscopy were indicated that single layers synthesis of graphene oxide (GO) sheets was formed successfully. Reduction of the GO to reduced graphene oxide (RGO) was chemically done by hydrazine as a conventional reducing agent and melatonin as a green alternative. Photocatalytic reduction and hybridization of GO with TiO2 was also studied. TEM, SEM and AFM analyses confirmed nucleation and growth of TiO2...
