Abstract: Abstract Alkali-treated zeolite material was prepared by using 0.1–0.4 mol/L NaOH aqueous solution, as characterized by XRD, SEM, N2 adsorption-desorption technique and ammonia-temperature programmed desorption (NH3-TPD). The as-prepared zeolite was found to be an effective catalyst… read more here.
