Summary: Hydrogen is an emerging clean fuel alternative, but its dependence on freshwater poses a threat to sustainability. Seawater, an abundant source, can be used as an alternative, but its high salt content causes corrosion and hinders its use. To overcome this, a unique catalyst composed of nitrogen-doped NiMo3P sheets with large homogenous pores is designed. The introduction of N and Ni optimizes surface energies, creates new active sites, and enhances stability, resulting in remarkable performance for hydrogen evolution and water splitting in seawater.

Summary: This study developed a low-cost and high-performance electrocatalyst for water splitting, which is crucial for hydrogen production. By introducing oxygen-deficient CeO2 nanoparticles on (Ni, Co)2P nanosheets, a high-performance hydrogen and oxygen evolution reaction bifunctional electrocatalyst was created. The introduction of defective CeO2 modulated the electronic structure of the CeO2@(Ni, Co)2P/NF interface, resulting in a synergistic effect that promotes the HER/OER reaction in alkaline water splitting.

Summary: In this study, Co single atoms dispersed on N and P co-doped porous carbon nanofibers were designed as electrocatalysts for efficient water splitting. The configuration of Co single atoms was proven to coordinate with 4 N/O atoms. The interaction between doped P atoms and Co-N-4(O) sites modulates the electronic structures, leading to reduced adsorption energies of intermediates during hydrogen evolution reaction (HER) and oxygen evolution reaction (OER). Density Functional Theory calculations revealed that Co single atom with P coordinated with two N atoms exhibited optimized HER and OER kinetics. The atomically dispersed Co electrocatalyst demonstrated low overpotentials for acidic HER, alkaline HER, and OER, along with promising Tafel slopes. This work demonstrates the potential of di-heteroatom-doping transition metal single atom catalysts and provides a novel strategy for their preparation.
