An Electrochromic Nickel Phosphate Film for Large-Area Smart …
2023年1月11日 · In this work, we proposed and demonstrated a large-area nickel phosphate (NiHPO 4 ·3H 2 O, NHP) EC film with homogeneous nanoparticles by a facile and scalable electrodeposition method. As a bifunctional film with electrochromism and energy storage, the NHP film showed large optical modulation with nearly 100% transmittance in the bleached ...
XPS spectra: a nickel, b phosphorus - ResearchGate
The hydrogen evolution reaction (HER) activity of different Ni–P nanoparticles hinges on elemental ratios of nickel to phosphorus and nickel phosphide phases through annealing processes, which...
the formation of nickel phosphide on the surface of a nickel foil was investigated, at temperatures like those employed to form nickel phosphide nanoparticles in the colloidal route. We uncovered that the onset of phosphorus insertion into nickel is as low as 150 °C, much lower than reported in …
Phase and composition controllable synthesis of nickel phosphide …
2017年12月20日 · In this paper, we demonstrate the phase and composition controllable synthesis of nickel phosphide-based nanoparticles (Ni P-based NPs) via a low-temperature phosphidation reaction (250 °C) using NaH 2 PO 2 as the phosphorus source and the as-prepared Ni(OH) 2 precursor as the nickel source.
Electrocatalytic layers for hydrogen evolution reaction based on nickel …
2022年5月16日 · X-ray photoelectron spectroscopy (XPS) is employed to evaluate the phase composition at the surface, highlighting the presence of a top layer characterized by a Ni2P/Ni12P5 ratio significantly lower than the value found in the bulk of the coating. Annealed NiP/P layers are tested for HER in 0.5 M sulphuric acid solution.
High-performance light-driven heterogeneous CO - Nature
2020年10月13日 · Selected as an archetype, Ni12P5 affords a structure based upon highly dispersed nickel nanoclusters integrated into a phosphorus lattice that harvest light intensely across the entire solar ...
Engineering nickel phosphides for electrocatalytic hydrogen …
2023年4月1日 · Among transition metal-based compounds, nickel phosphides (Ni x P y) have emerged as one of the most nascent and low-cost candidates with unique properties and unprecedented HER performances. Motivated by the complexity, tunability and diversity of Ni x P y structure, the doping of Ni x P y emerges as a pivotal and effective strategy to ...
