The evolution of nanomaterials has been critical in modifying materials at the nanoscale for specialized uses. Carbon nanotubes were initially viewed as promising for electronics, but their inability to discriminate between semiconducting and metallic phases led to the creation of quasi-two-dimensional (Q-2D) materials<sub>.</sub> Molybdenum nanoparticles are utilized as alloy additions in corrosive and high-vacuum environments. Their characteristics differ significantly from those of their bulk counterparts.<sub> </sub>This review analyses the use of molybdenum oxide compounds in electrical devices, sensors, and memory devices. Their fascinating electrical conductivity and programmable characteristics give prospects for developing innovative electronic components. Furthermore, their performance in new technologies, such as flexible electronics and wearable devices, is evaluated. Molybdenum oxide compounds are incredibly versatile and can be used in various applications, including energy storage, electronics, and catalysis. Their essential use for tackling current materials science and technology issues has been discussed. The classifications, structural variations, and basic properties of molybdenum oxide compounds are covered in this paper, which offers a solid basis for comprehending the range of applications for these compounds. This review paper explores the catalytic processes, the challenges, and their critical significance in enabling environmentally remedial and sustainable chemical transformations.
