A novel NiS nanocatalyst is synthesized by using simple coordination complex as precursors through an economic and straightforward sulfidation method, resulting in a high-performance catalyst for reduction of 4-nitrophenol (4-NP). The NiS nanocatalyst possess dispersed catalytic nanoparticles, high porosity and good electroactivity, leading to provide facile pathways for electron transfer. The as-prepared NiS nannocatalyst exhibits unusual catalytic activity according to fast apparent rate constant (k_app) of 1.413 min⁻¹ and turn over frequency (TOF) of 2.5 × 10⁻³ mol·g⁻¹·min⁻¹. As expected, these structural features bring good catalytic properties to methyl orange (MO) reduction. It is expected this work will presents a practical experiment for using simple coordination complex as sacrificial templates to synthesize nanoparticles for wide applications.
