Synthesis, Characterization and Photoelectrochemical Application of two Dimensional MoS2 and WS2 Nanosheets, Ph.D. Dissertation Sharif University of Technology ; Zaker Moshfegh, AliReza (Supervisor) ; Moradlou, Omran (Co-Advisor)
Abstract
In this research, Synthesis, characterization and photoelectrochemical application of two dimensional MoS2 and WS2 nanosheets have been carefully investigated. And finally, based on theoritical and experimental analysis results, the mechanisms of the observed photoelectrochemical (PEC) activities were suggested.The ab initio density functional calculations about Mo1-xWxS2 monolayer deposited over a TiO2 (110) substrate revealed a shift in band position of the Mo1-xWxS2 in favor of photoelectrochemical water splitting. Moreover, increase of W concentration in Mo1-xWxS2 could improve the charge separation and increase the effective mass ratio leading to an extension of the electron–hole...
