Abstract The MoSe2/phosphorus-doped graphene nanocomposite (FL-MoSe2/PG) was successfully prepared through a simple tetrabutylphosphonium bromide-mediated hydrothermal and annealing procedure. The resultant nanocomposite was examined by X-ray photoelectron spectra (XPS), X-ray diffraction (XRD), Raman spectroscopy, high-resolution transmission electron microscopy (HRTEM) and scanning electron microscopy (SEM). The results revealed that the MoSe2 nanosheets were of few-layered (2–4 layers) and defective features and were well supported on the conductive phosphorus-doped graphene to form composite. Additionally, the electrochemical reversible sodium storage performance and electrocatalytic activity for hydrogen evolution reaction (HER) were also investigated. As a result, the FL-MoSe2/PG-based electrode exhibited obviously better electrochemical property than the pristine MoSe2 due to its desirable structure merits.
