Abstract

Under ambient pressure, an aqueous solution may not enter the nanopores of a hydrophobic ZSM-5 zeolite, which imposes difficulties to cation-exchange treatment. In the current study, a high-pressure cation-exchange technique is developed. With a relatively short treatment time, the degree of hydrophobicity is significantly increased.
