“…The high-resolution XPS spectrum of BP is displayed in Figure a. The P 2p region of BP shows two fitted peaks with binding energies of ∼129.00 and 129.70 eV respectively corresponding to the 2p 3/2 and 2p 1/2 signals of elemental P. Additionally, the observed three peaks at 131.41, 133.28, and 134.60 eV could be associated with P–O, PO, and P 2 O 5 , respectively . The BP oxidation can be further confirmed by the O 1s XPS spectrum (Figure S9a).…”

The oxidized phosphorus on the surface of the material corroborates that BP is susceptible to reacting spontaneously with the O 2 in air, which is in agreement with the XRD results as well.…”

The charge-carrier separation efficiency is one of the important factors for a high photocatalytic performance. Herein, a nickel phosphide (Ni2P) cocatalyst chemically bonded to black phosphorus (BP) nanosheets (0D/2D Ni2P/BP) has been synthesized by a facile one-step solvothermal process, using the commercial red phosphorus (RP) as a precursor material. RP is used not only to synthesize BP but also to form in situ Ni2P as a cocatalyst for the host BP photocatalyst. The in situ grown Ni2P on BP nanosheets leads to the creation of a Ni–P covalent bond, which enhances the charge separation as well as material stability. Thus, the developed nanocomposite was found to be efficient toward photocatalytic H2 production at a rate of 406.08 μmol·g–1·h–1 under sunlight with high apparent quantum yields of around 48.45 and 7.90% at 360 and 400 nm, respectively. Notably, the Ni2P/BP composite is found to be more efficient compared to the Pt/BP composite. As confirmed by the comparative study between the chemically and physically loaded Ni2P nanocomposites, the Ni–P bonds enhance the interfacial charge-carrier separation at the interface of BP and Ni2P, which ultimately increase the lifetime of the photogenerated electrons and improve the photocatalytic performance. The obtained results demonstrate that the established in situ one-step solvothermal synthesis strategy can be viable for the scalable synthesis of the developed materials for the large-scale H2 production under solar light.
