CoFeP/NC@CoP/Ni₂P heterostructure for efficient overall water splitting

Abstract

Reasonable design and construction of low-cost overall water splitting catalyst with high efficiency is of great significance to green chemistry industry. Herein, a CoFeP/NC@CoP/Ni2P heterostructure is constructed via phosphiding CoFe-Prussian...

Electrocatalytic Reforming of Polylactic Acid Plastic Hydrolysate over Dynamically Formed γ-NiOOH

“…The survey XPS spectrum clearly displayed Ni and P, with the Ni 2p spectrum showing contributions at 874 and 857 eV for Ni­(II) and satellite peaks at 880 and 862 eV (Figure d). Notably, the peaks at 853 and 870 eV were attributed to nickel phosphorus species, consistent with previous reports. − The P 2p spectrum indicated the existence of two chemical environments for phosphorus species: the dominant peak at 129 eV was characteristic of Ni 2 P, and the second peak at 134 eV represented phosphorus in an oxidizing environment (Figure S4). Apparently, the formation of phosphorus–oxygen bonds was mainly due to the oxidation of the Ni 2 P surface after exposure to air, , in agreement with the results of EDS (Figure S5).…”

Boride-induced phase tuning of defect-introduced MoS2 nanosheets to boost the electrocatalytic hydrogen evolution reaction

“…3f). As reported previously, 44,45 the NaBH 4 treatment led to the incorporation of boron species into the MoS 2 lattice. The resulting increase of Mo oxidation state caused by boron doping induced a phase transition of highly distorted 1T ′ MoS 2 to ordered 2H MoS 2 upon NaBH 4 treatment, which would be responsible for the improvement of structural order in the MoS 2 lattice (Fig.…”

Molybdate intercalated nickel–iron-layered double hydroxide derived Mo-doped nickel–iron phosphide nanoflowers for efficient oxygen evolution reaction

“…For the P 2p spectrum shown in Fig. 3d, the BEs at 129.58 eV (P 2p 3/2 ), 130.28 eV (P 2p 1/2 ), and 134.18 eV are assigned to metal phosphides and the P-O bond [41,42] .…”
