摘要: The exploration of a highly efficient catalyst for the hydrolysis sodium borohydride (NaBH4) is valuable step toward hydrogen economy. UiO-66 (Universitetet i Oslo) was synthesized via solvothermal method using acetic acid as modulator. material characterized X-ray diffraction (XRD), nitrogen adsorption–desorption isotherms, Fourier transform infrared (FT-IR) spectroscopy, thermogravimetric analysis (TGA), temperature-programmed desorption (TPD), and transmission electron microscopy (TEM). Data reveals formation pure crystalline phase with Brunauer–Emmett–Teller (BET) Langmuir specific surface areas 1125 m2 g−1, 1250 respectively. analysed generation NaBH4. effect NaBH4 amount loading investigated. reaction time decreased an increase or UiO-66. exhibited average rate 6200 mL min−1 g−1. high catalytic performance could be due to its large area acidic sites. results suggested that showed potential catalyze production hydrides.
