This review paper provides an overview of inorganic corrosion inhibitors, including their types, mechanisms of action, applications, recent advances, and future directions. Inorganic corrosion inhibitors have been widely used to protect metals and alloys from corrosion in various industries, such as oil and gas, chemical, and construction industries. The different types of inorganic corrosion inhibitors discussed in this review include metal-based, metal oxide-based, phosphate-based, silicate-based, and other inorganic inhibitors. The mechanisms of action of inorganic corrosion inhibitors are mainly related to their adsorption on metal surfaces, formation of protective films, and cathodic and anodic polarization. The paper also highlights the applications of inorganic corrosion inhibitors in different industries and discusses their effectiveness and limitations. Recent advances in the field of inorganic corrosion inhibitors, such as nanotechnology-based inhibitors, green inhibitors, combination inhibitors, and computational studies, are also reviewed. In conclusion, this paper summarizes the key findings of the review and provides a future outlook for the development of inorganic corrosion inhibitors. The review concludes that further research is needed to develop more effective, environmentally friendly, and economical inorganic corrosion inhibitors for various industrial applications.
