摘要
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.
