“…Among these oxides, MoO 3 is an abundant natural and sustainable material that has gained considerable attention due to its chemistry related to multivalent Mo, high thermal and chemical stability, and redox chemistry resulting from its high reduction potential and electrochemical activity [2][3][4][5]. Due to its large band gap and optical and electrical properties, MoO 3 is considered a potential and appropriate material for various technological applications in the fields of photocatalysis, adsorption, gas sensing, battery electrodes as anodic and cathodic materials, recording material, electrochromic and photochromic materials, organic solar cells, and organic light-emitting diodes as a buffer layer and as a catalyst for the electrochemical reduction in several ions [6][7][8]. Interestingly, MoO 3 and MoO 3−x oxides have been used as hole injection/extraction interlayers in organic solar cells in order to modify the anode contact due to their high work function and their ability to exchange charges with several semiconductors, which requires the energylevel alignment of the materials.…”

Molybdenum trioxide is an abundant natural, low-cost, and environmentally friendly material that has gained considerable attention from many researchers in a variety of high-impact applications. It is an attractive inorganic oxide that has been widely studied because of its layered structure, which results in intercalation ability through tetrahedral/octahedral holes and extension channels and leads to superior charge transfer. Shape-related properties such as high specific capacities, the presence of exposed active sites on the oxygen-rich structure, and its natural tendency to oxygen vacancy that leads to a high ionic conductivity are also attractive to technological applications. Due to its chemistry with multiple valence states, high thermal and chemical stability, high reduction potential, and electrochemical activity, many studies have focused on the development of molybdenum oxide-based systems in the last few years. Thus, this article aims to briefly review the latest advances in technological applications of MoO3 and MoO3-based materials in gas sensors, lithium-ion batteries, and water pollution treatment using adsorption and photocatalysis techniques, presenting the most relevant and new information on heterostructures, metal doping, and non-stoichiometric MoO3−x.
