Abstract : Transition metal dichalcogenides (TMDs), particularly molybdenum disulfide (MoS2) and molybdenum diselenide (MoSe2), have garnered significant attention due to their potential use in electrochemical sensors and batteries. They proved their immense potential in this field because of their unique as well as superior optical, electrical, and physical properties. The review thoroughly examines the influence on electrochemical performance in both areas due to the engineering of MoS2 and MoSe2, achieved with the aid of other TMDs, covalent organic framework, metal oxides, carbon-based materials, and metal doping. The techniques used to synthesize these materials are discussed herein, alongside an examination of their structural properties. Furthermore, an exploration is conducted into surface alterations that enhance their performance. The utilization of engineered MoS2 and MoSe2 in diverse electrochemical sensors, encompassing those designed for the detection of biomolecules, drugs, food contaminants, and environmental pollutants, is emphasized. Furthermore, they exhibited outstanding performance as electrode materials in batteries by demonstrating extraordinary rate performance and extended cycle life most of the time. The text also highlights the potential of these materials to generate innovations in energy storage and sensing technologies while discussing the fundamental difficulties and prospects for their use in these areas.
