Facile synthesis of PVP surfactant-aided MoO3/g-C3N4 nanocomposites improves the performance of photocatalytic dye degradation and electrocatalytic overall water-splitting bustle

This work describes the MoO₃/g-C₃N₄ nanocomposite that has been synthesized via a hydrothermal process and it demonstrates a potential application designed for photocatalytic RhB dye degradation and electrocatalytic overall water splitting. Hence the XRD, FT-IR, UV-DRS, SEM, TEM and XPS characterized the functional electrode's morphological, optical, and structural characteristics. These techniques revealed that the g-C₃N₄ surfaces were effectively MoO₃ nanocrystals without any other unwanted species formation. The MoO₃/g-C₃N₄ nanocomposite demonstrates superior photocatalytic RhB dye degradation under alternating sunlight irradiation up to 88% for 60 min. The Electrocatalytic overall water-splitting performance is evaluated by LSV, chronoamperometry, chronopotentiometry, and EIS analysis which exhibit higher current density, good stability, low overpotential, and small Tafel slop of the MoO₃/g-C₃N₄ nanocomposite than bare MoO₃ catalyst.
