Abstract
Supported NiCo2O4 catalyst (NiCo2O4/zeolite) was prepared by homogeneous co-precipitation combined with a sintering method. The NiCo2O4/zeolite catalyst was characterized by XRD, BET, FESEM coupled with EDS, and XPS. The results indicated that NiCo2O4 microspheres produced excellent growth on the zeolite, constructing porous structures. Moreover, the NiCo2O4/zeolite catalyst exhibited high activity for NaBH4 hydrolysis (experiment showed that the zeolite carrier had no catalytic activity for NaBH4 hydrolysis); the hydrogen generation rate was as high as ∼6219 ml·min-1·g-1. Furthermore, the kinetics of NaBH4 hydrolysis was systematically studied by changing the temperature, the NiCo2O4/zeolite catalyst dosage, concentrations of NaOH and NaBH4. According to the power law model, the overall kinetic rate expression of NaBH4 hydrolysis using NiCo2O4/zeolite catalyst was Additionally, the NiCo2O4/zeolite catalyst was highly recyclable which demonstrated its durability , making this material suitable for practical applications in PEMFC and portable devices.
