“…Along with the enhancemento fl aser pulse energy,t he percentage of Ni 3 + gradually increases (Figure 4), and so does the catalytic performance of CoNiPO 4 (L) (Figure 4a nd Figure S15). The CoNiPO 4 (L) produced at the pulse energy of 541 mJ achieves the lowest overpotential, and furtheri ncrease of the pulse energy leads to worse performance, which should be attributed to the decompositiono f phosphate, [43,44] according to the infrared spectrum (Figure S16).…”

Cost‐effective, highly efficient and stable non‐noble metal‐based catalysts for the oxygen evolution reaction (OER) are very crucial for energy storage and conversion. Here, an amorphous cobalt nickel phosphate (CoNiPO4), containing a considerable amount of high‐valence Ni3+ species as an efficient electrocatalyst for OER in alkaline solution, is reported. The catalyst was converted from Co‐doped Ni2P through pulsed laser ablation in liquid (PLAL) and exhibits a large specific surface area of 162.5 m2 g−1 and a low overpotential of 238 mV at 10 mA cm−2 with a Tafel slope of 46 mV dec−1, which is much lower than those of commercial RuO2 and IrO2. This work demonstrates that PLAL is a powerful technology for generating amorphous CoNiPO4 with high‐valence Ni3+, thus paving a new way towards highly effective OER catalysts.

“…It was shown in [26,27] that an increase in the phosphorus content on the coating surface can be achieved by treating it in a nitric acid solution. However, the phase composition and structure of the surface layers enriched in phosphorus are poorly studied [28], and the possibility of obtaining nickel phosphide phases as a result of heating the treated coatings has not been investigated either.…”

Nickel phosphides NixPy are a promising family of binary compounds that have shown much promise in various fields of technology, including energy storage, light absorption and heterogeneous catalysis in the reactions of biomass hydrogenation. The performance of NixPy-containing materials depends greatly on their morphology and phase composition and, in turn, on the synthesis technique. In this work, we have employed the electroplating approach to synthesize a Ni-P coating, which was treated with nitric acid in order to develop its surface area and enrich it with phosphorus. We have employed scanning electron microscopy, X-ray diffraction and 31P nuclear magnetic resonance techniques to characterize the particles separated from the coating with ultrasound for the convenience of the study. According to experimental data, the obtained powder contained a mixture of Ni3P and phosphorus oxides, which transformed into nickel phosphide phases richer with phosphorus, such as Ni5P2 and Ni12P5, after treatment at elevated temperatures. Thus, we have demonstrated that electroplating followed by acid treatment is a feasible approach for the synthesis of Ni-P coatings with increased surface area and variable phase composition.
