The unique characteristics and diverse applications of 2D transition metal phosphides have aroused significant interest. In this paper, we successfully prepared 2D NiCoP modified ZnCdS composite. The NiCoP nanosheets were successfully obtained by phosphating layered double hydroxide (LDH) precursor. The results show that the ZnCdS-8%NiCoP has the highest photocatalytic performance among all the composite photocatalysts with the H evolution rate of 1370.1 µmol h, which is 17.9 folds higher than obtained with pure ZnCdS. Detailed analysis reveal that NiCoP nanosheets functions as an excellent electron acceptor, speeding up the directed migration of electrons. Furthermore, the rational mechanism of photocatalytic has been presented based on density function theory (DFT) calculations, which is well congruent with experimental results. Our research offers a simple, environmentally benign, and scalable technique for making highly effective photocatalysts, as well as a novel perspective on transition metal phosphides rational design.

Hydrogen production via seawater electrolysis is regarded as a promising avenue for utilizing sustainable energy. However, developing an efficient electrocatalyst with low overpotential and high chloride corrosion resistance remains a considerable challenge. In this research, a heterostructure NiCoP/Ce-NiCo LDH catalyst was fabricated by a simple hydrothermal-phosphorization-electrodeposition method.

Developing highly active and robust bifunctional electrocatalysts for overall water splitting is of great significance for the production of green hydrogen energy. Herein, heterostructured CoP/NiCoP nanoparticles that are encapsulated one-to-one in nano caves of soda-biscuit-like ultrathin carbon nanosheets (CoP/NiCoP/CMS) are prepared, using melamine-formaldehyde sponge (MS) that grew Co/NiCo hydroxides as precursor and phytic acid (PA) as phosphorus source. Especially, the PA-induced blowing behavior during pyrolysis not only transforms the 3D networks of MS into 2D ultrathin carbon nanosheets of CMS, but also achieves the uniform one-to-one superconfinement of hetero-nanoparticles within both the intralayer nanocaves and interlayer spaces of the carbon nanosheets.

Efficient hydrogen (H) generation from electrochemical overall water splitting (OWS) is key to a sustainable H economy. Low-cost transition metal-based catalysts, such as Ni- and Co-based phosphides, have gained attention for the hydrogen evolution reaction (HER) and oxygen evolution reaction (OER) due to their excellent corrosion resistance and high electrical conductivity. In particular, bimetallic Ni and Co-based phosphide catalysts are considered highly efficient electrocatalysts for OWS due to their abundant adsorption sites and low adsorption energy for hydrogen species.

Efficient and cost-effective photocatalysts are crucial for solar-to-H conversion. Here, we report a highly active photocatalyst with uniform 0D ZnSe nanoparticles modified by 2D bimetallic NiCoP nanosheets. The optimized 2D/0D NiCoP/ZnSe heterostructure achieves a H evolution rate of 4271 μmol g h, significantly surpassing pristine ZnSe and the monometallic phosphide counterparts NiP/ZnSe and CoP-CoP/ZnSe.

Water dissociation in anion exchange membrane water electrolysis (AEMWE) faces significant energy barriers, posing a challenge for reducing cell voltage. Herein, we engineered CoP nanosheets by doping Er and hybridizing with NiCoP to optimize local electronic states and accelerate HO dissociation during the hydrogen evolution reaction. The resulting Er-CoP/NiCoP catalyst achieves a low overpotential of 154 mV at -500 mA cm in 1.
