Layered transition metal selenides have garnered widespread attention as the potential non-noble metal-based materials to cater diverse energy conversion and storage aspects. Therefore, we implemented an integrated experimental theoretical methodology explore application of molybdenum diselenide (MoSe2) for HER, OER, supercapacitor avenues via employing nanostructural surface engineering performance enhancement strategy. Herein, demonstrated successful execution a laboratory-scale electrolyzer water splitting with low cell voltage 1.54 V at 10 mA cm-2 current rate 50 hrs. This was accomplished using synthesized exfoliated conductive carbon enwrapped MoSe2-E/C material. Further, DFT calculations revealed origin better electrochemical on MoSe2-E (103) plane. Moreover, showcased high capacitance 734 F g-1 (@ 1 A g-1) 472 20 in three-electrode setup symmetric configuration respectively along capacity retention 95.02% density after 2000 cycles. Hence, prepared material exhibited its pertinence rendering distinctive energy-related challenges owing unique structural arrangement.
