Gas sensor performances of α-MoO3 belts nanostructured with Pd

Abstract

Molybdenum trioxide (MoO3) due to its unique physical and chemical properties is one of the most attractive candidates for different promising technological applications]. (MoO3 has a unique morphology that resembles a structure of layered graphene. Due to the layered structure and high chemical stability MoO3 is used for such applications as gas sensors, recording or storage materials, lubricants, electrochromism, and fotochromism. Meanwhile, MoO3 is a promising material for catalysts [4], the field emission, light emitting diode, and energy storage elements, etc., because of its electrical and optical propierties. Nanobelts shaped nanostructures of MoO3 are of major interest due to various gas properties and simple integration technology for bottom-up and the possibility of obtaining cost-effective technologies. Their major drawback is the high surface-to-volume ratio.
