Abstract
The Ni2P nanowires were simply synthesized via a rapid one-step hydrothermal approach, in which deionized water, red phosphorus, nickel acetate, and hexadecyl trimethyl ammonium bromide were used as the solvent, phosphor and nickel sources, and active agent, respectively. The as-synthesized Ni2P nanowire clusters were composed of uniform nanowires with length of about 10 μm and diameter of about 40 nm. The Ni2P nanowires exhibited enhanced electrocatalytic activity for both hydrogen evolution reaction and oxygen evolution reaction This work provides good guidance for the rational design of nickel phosphides with unique nanostructures for highly efficient overall water splitting.
Highlights
We report a facile one-pot synthesis of Ni2P nanowire clusters using the hydrothermal method and the as-prepared Ni2P nanowires exhibit enhanced electrocatalytic activity for both hydrogen evolution reaction (HER) and oxygen evolution reaction (OER)
The orientation of most nanowires is in the same direction as in Figure 2A, and there are numerous hump-like particles on the surface of the nanowires in Figure 2B, exposing a large number of active sites during the electrocatalysis process
The as-synthesized Ni2P is composed of nanowire clusters with a uniform length of about 10 μm and a diameter of about 40 nm
Summary
Growing energy demands and worsening environmental issues have motivated a large amount of research into developing efficient energy conversion/storage systems for sustainable alternatives (Tan et al, 2020; Ji et al, 2021), e.g., Li-ion batteries (Chen et al, 2016; Zhang et al, 2017a; Li et al, 2017), supercapacitor (Wang et al, 2020; Zhao et al, 2021), water splitting (Wang et al, 2016a; Wang et al, 2016b; Swierk and Mallouk, 2017), and fuel cells (Debe, 2012). We report a facile one-pot synthesis of Ni2P nanowire clusters using the hydrothermal method and the as-prepared Ni2P nanowires exhibit enhanced electrocatalytic activity for both HER and OER.
