Two-dimensional (2D) metal oxides have aroused increasing attention in the field of electronics and optoelectronics due to their intriguing physical properties. In this review paper, an overview of recent advances on synthesis of 2D metal oxides and their electronic applications is presented. First, the tunable physical properties of 2D metal oxides that related to the structure (various oxidation-state forms, polymorphism, etc.), crystalline and defects (anisotropy, point defects, and grain boundary), and thickness (quantum confinement effect, interfacial effect, etc.) are discussed. Then, advanced synthesis method for 2D metal oxides besides mechanical exfoliation are introduced and classified into solution process, vapor phase deposition, and native oxidation on metal source. Later, the various roles of 2D metal oxides in widespread applications, i.e., transistors, inverters, photodetectors, piezotronics, memristors, and potential applications (solar cell, spintronics and superconducting devices) are discussed. Finally, the outlook of existing challenges and future opportunities in 2D metal oxides are proposed.
