Title: Facile and low cost oxidative conversion of MoS{sub 2} in α-MoO{sub 3}: Synthesis, characterization and application

Abstract

This study describes a facile low cost route to synthesize the α-MoO{sub 3} through a conversion of the precursor MoS{sub 2} in oxidant media. The structure and morphology of the α-MoO{sub 3} were studied by high resolution transmission electron microscopy (HRTEM) and selected area electron diffraction (SAED), X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS) and Raman spectroscopy. The results show that α-MoO{sub 3} was obtained with reduced size, high purity, strongly-preferred orientation and structural defects, which ensures versatility and multifunctionality to this sample. For the purpose of applications, α-MoO{sub 3} was successfully employed in inverted organic solar cells devices as a possible alternative to the PEDOT:PSS in the hole transportation layer. - Graphical abstract: Synthesis process based on low cost oxidative conversion of MoS{sub 2} in α-MoO{sub 3} Display Omitted - Highlights: • A facile route to obtain α-MoO{sub 3} by refluxing the MoS{sub 2} precursor in oxidant media. • High purity and strongly-preferred orientation. • Belt-shaped material. • Enhanced conversion efficiency (PCE) when compared with conventional PEDOT:PSS.
