- Abstract
The preparation of high-efficiency electrocatalysts for the oxygen and hydrogen evolution process (OER and HER) using an easy, green, and facile preparation method is crucial for the effective and economical use of clean energy sources. We report here an eco-friendly phytic acid (PA)-assisted phosphidation strategy to synthesize a novel Cu 3 P decorated on N-doped carbon (Cu 3 P-NC). Its synthesis involves precipitation of rode-like microstructured Cu-based aspartic acid frameworks (Asp-Cu MOF), chemical etching of Asp-Cu MOF to form PA cross-linked Cu complexes, and a final pyrolysis step to get Cu 3 P-NC with abundant Cu 3 P nanoparticles loaded on N-doped carbon matrix. The Cu 3 P-NC catalyst demonstrates catalytic performances with low overpotentials of 116 and 310 mV at 10 mA cm−2, small Tafel slopes of 61.2 and 69.2 mV dec−1, for HER and OER respectively, and high catalytic durability in 1 M KOH. The as-prepared Cu 3 P-NC electrocatalyst offers a new viewpoint on developing multi-functional electrocatalysts in the water-splitting process using environment-friendly substances such as amino acids. [Display omitted] • The Cu 3 P-NC is fabricated as promising electrocatalyst in OER and HER. • The synergistic effect among Cu 3 P NPs and NC improves electrical conductivity. • The Cu 3 P-NC exhibits a favorable prospect for development of electrocatalysts based on amino acids.
