 The transition metal tricalcogenides, TMTCs, are quasi-1-idimensional 1D-MX3 type vander walls layered semiconductors, which exhibit unique properties such as variable band gaps, charge density waves, and superconductivity. These materials also display an isotropic optical, thermoelectric, and magnetic properties, making them ideal candidates for use in nano-electronics. In this review, we discuss the synthetic methods used to produce these materials, their physical properties, and their potential applications in photo detectors, energy storage devices, catalysts, and sensors. We also provide an overview of the opportunities and future perspectives for the research of TMTCs, as well as the challenges in both basic research and practical applications.
