Abstract
Electrocatalytic water splitting is an environmentally friendly approach for producing hydrogen and oxygen from water. ZnSe@d-Ti3CNTx nanocomposite was synthesized by a hydrothermal approach. The ZnSe@d-Ti3CNTx nanocomposite was examined with several techniques, including Raman, p-XRD, microscopy, SEM/EDS, and XPS spectroscopy. Electrochemical properties were studied by CV, LSV, EIS, and chronoamperometry. As Ti3CN is a conductive material, to improve its electron transport efficiency, ZnSe was incorporated into it, which not only enhances its electrochemical behavior but also prevents it from restacking. By integrating the features of d-Ti3CNTX MXene and ZnSe nanoparticles, the HER and OER performance of the electrocatalyst is improved at low overpotentials of 270 mV and 232 mV, respectively. The ZnSe@d-Ti3CNTx nanocomposite.kept 84 % of its starting current after 50 h at an applied potential of 1.56 V, demonstrating excellent long-term stability. According to the results of this research, the ZnSe@d-Ti3CNTx nanocomposite has the potential to serve as a highly efficient and long-lasting electrocatalytic catalyst for water splitting.
