Construction of interface-engineered coral-like nickel phosphide@cerium oxide hybrid nanoarrays to boost electrocatalytic hydrogen evolution performance in alkaline water/seawater electrolytes
Fabricating a functional heterogeneous interface to enhance catalytic performance is quite significant for developing high-efficiency electrocatalysts. Herein, a coral-like nickel phosphide@cerium oxide (Ni2P@CeO2) hybrid nanoarray on nickel foam was designed via selective-phosphorization of nickel hydroxide@cerium oxide (Ni(OH)2@CeO2). Benefiting from CeO2 as the “electron pump,” it leads to electron transfer from Ni2P to the CeO2 side, and induces electron redistribution in the interface boundary, thereby optimizing the H* adsorption free energy in the hydrogen evolution reaction (HER) process. As hypothesized, the water molecules will preferentially adsorb on the CeO2 side due to its better affinity for oxygen-containing species, and will readily break down into OH* and H* at a lower energy barrier. Subsequently, benefiting from the lower H* adsorption free energy of P sites, the generated H* will migrate to the Ni2P side through the spillover process. Contributing to the synergistic effect of double-active sites, the Ni2P@CeO2/NF electrode exhibits brilliant catalytic performance for HER with 62 mV to attain 10 mA/cm2 and exceptional durability over 100 h in alkaline solution at ~ 100 mA/cm2. Meanwhile, attributing to the similar interface electron redistribution effect, the precursor Ni(OH)2@CeO2/NF likewise displays excellent oxygen evolution reaction (OER) electrocatalytic performance, which only requires 229 mV to arrive at 10 mA/cm2, even better than benchmark ruthenium dioxide (RuO2). Hence, the assembled Ni(OH)2@CeO2/NF||Ni2P@CeO2/NF system only needs 1.53 V to achieve 10 mA/cm2 in alkaline solution. Moreover, the electrolyzer also presents brilliant electrocatalytic activity and stability in alkaline natural seawater electrolyte with higher reserves on earth.
Graphical Abstract
“Electrons pump” effect of CeO2 ensures that interface-engineered Ni2P@CeO2 hybrid nanoarrays prepared via selective-phosphorization treatment present superior HER catalytic performance
期刊介绍：
Advanced Composites and Hybrid Materials is a leading international journal that promotes interdisciplinary collaboration among materials scientists, engineers, chemists, biologists, and physicists working on composites, including nanocomposites. Our aim is to facilitate rapid scientific communication in this field.
The journal publishes high-quality research on various aspects of composite materials, including materials design, surface and interface science/engineering, manufacturing, structure control, property design, device fabrication, and other applications. We also welcome simulation and modeling studies that are relevant to composites. Additionally, papers focusing on the relationship between fillers and the matrix are of particular interest.
Our scope includes polymer, metal, and ceramic matrices, with a special emphasis on reviews and meta-analyses related to materials selection. We cover a wide range of topics, including transport properties, strategies for controlling interfaces and composition distribution, bottom-up assembly of nanocomposites, highly porous and high-density composites, electronic structure design, materials synergisms, and thermoelectric materials.
Advanced Composites and Hybrid Materials follows a rigorous single-blind peer-review process to ensure the quality and integrity of the published work.
