The thermal annealing method is regarded as a general and promising method for preparation of carbon-based electrocatalysts. However, this method always suffers from complex and harsh preparative conditions, such as high pyrolysis temperature, protective gas environment, and long synthesis period. Herein, a laser engraving method is introduced for preparation of porous nitrogen-doped graphene layer-enclosed FeNi nanoparticles (FeNi/PNGs), starting with metal organic frameworks (MOFs) as precursors. All the steps were quickly achieved at room temperature and in air environment. Another attractive feature of this method is that FeNi/PNG supported on polyamide (PI) film could directly act as electrocatalytic electrode for hydrogen (HER) and oxygen evolution reaction (OER) without the involvement of dispersion and drop-casting of electrocatalyst ink. The FeNi/PNG shows overpotentials of 132 and 353 mV with Tafel slope of 94 and 80 mV dec(-1) for HER and OER catalyses, respectively. This simple and convenient method could be extended to other catalytic systems with carbon-based materials as electrocatalysts.
