Hydrothermal approach for the synthesis of FeSe2/Ti3CNTx and its applications towards water splitting and energy storage

Different materials were used for energy production and energy storage applications. In this study, MXene was combined with FeSe2 2 to develop a novel and efficient catalyst. FeSe2/Ti3CNTx 2 /Ti 3 CNT x was used for water splitting as well as energy storage. HER and OER were performed to find out its efficiency for water splitting. The overpotential observed by the material is 317.18 mV for HER and 309 mV for OER with a Tafel slope of 149.15 mV.dec-1- 1 and 2.47 mV.dec-- 1 respectively. In symmetrical system testing for water splitting using two-electrode cell, a potential difference of 1.54 mV was observed. Observing the behavior towards water splitting, synthesized material is also tested for energy storage to fulfill the era's demand. Capacitance was determined at different current densities and 232 F.g-- 1 specific capacitance was observed at the current densities of 0.5 A.g-1.- 1 . Good capacity retention was observed and after 170 cycles columbic efficiency became constant which remained constant till 1000 cycles. This approach leads to a new way towards green energy production as well as energy storage.
