Abstract

Oxidation of two-dimensional (2D) transition metal dichalcogenides have received great interests because it significantly influences their electrical, optical, and catalytic properties. Monoclinic MoO2 nanowires grow along the zigzag direction of 2D MoS2 via thermal annealing at a high temperature with a low oxygen partial pressure. The hybrids of semiconducting 2D MoS2 and metallic 1D MoO2 nanowires have potential to be applied to various devices such as electrical devices, gas sensors, photodetectors, and catalysts.

Highlights

Oxidation of two-dimensional (2D) transition metal dichalcogenides have received great interests because it significantly influences their electrical, optical, and catalytic properties
Heterostructure of transition metal oxides (TMOs) and transition metal dichalcogenides (TMDs) are emerging as promising candidates for functional devices such as gas sensor, photodetector, and catalyst
Oxidation into MoO3 is common phenomenon in ambient conditions, but metallic MoO2 nanowires grow at a high temperature with a low oxygen partial pressure

Summary

Introduction

Oxidation of two-dimensional (2D) transition metal dichalcogenides have received great interests because it significantly influences their electrical, optical, and catalytic properties. Description Two-dimensional (2D) transition metal dichalcogenides (TMDs) have received great interests because of their outstanding electrical, optical, and catalytic properties. These properties are significantly influenced by oxidation. Heterostructure of transition metal oxides (TMOs) and TMDs are emerging as promising candidates for functional devices such as gas sensor, photodetector, and catalyst.
