N2 - A two-phase synthesis has been introduced to investigate the formation of NiCo2O4 nanoparticles at the interface of hexane-water, which was facilitated by Bryophyllum pinnatum (Lam) Oken leaf extract (BPLE) as hydrolyzing and capping agents via the high-speed stirring method. As a result, the morphology of NiCo2O4 was observed in the nanosphere with an average particle diameter of 25.84 nm. Furthermore, the catalytic performance of NiCo2O4 nanoparticles was investigated in the reduction of 2,4,6-trinitrophenol (TNP). Surprisingly, NiCo2O4 nanoparticles achieved a catalytic performance with a percentage of 96.03% within 24 min. The superior efficiency of catalyst could be attributed to the effective electron relay between 4-NP and BH4− ions at an optimum concentration of TNP. Additionally, NiCo2O4 nanoparticles exhibited high stability in four consecutive cycles. This work suggests a novel method for the preparation of NiCo2O4 on a nano-scale as a promising catalyst for eliminating water pollutants.
